Samantha "Sam" Manson
Maddie Fenton (Mom)
When Danny chases the ectopus into the pool room, the door handle continually switches sides.
When Danny is explaining the situation to Tucker he says that he got hit in the face with a rock. But since he was intangible as well as invisible, it just passed through him.
When we first see Sam and Gregor sitting at a table eating spaghetti, Sam is sitting on the left. But when we see her a little while later at the same table, she is sitting on the right and Gregor is on the left.
When the Guys in White walk out of a store in the mall, each of them is carrying one bag. After their ghost alarm goes off, the second Guy in White isn't carrying a bag anymore.
It seems a bit hypocritical that Sam got upset that Danny was spying on her. She basically did the same thing during Danny's brief romance with Valerie in Flirting With Disaster.
If Gregor claims to be a vegetarian, why is he eating a burger at the Nasty Burger? (note: that might have been a veggie burger, Sam gets them there from time to time)
The Guys In White tell their boss that in Hungary, black is the new white. However, according to Gregor white was the new black, not the other way around. And the Guys In White wouldn't have known that--they weren't nearby when Gregor said this anyway.
The Guys in White said that Mr. Lancer assigned an assignment on the purple-back gorilla, but Mr. Lancer didn't assign it; Danny just did it for extra credit to bring his D grade up. Furthermore, it was Sam's idea to do it on the purple-back gorilla.
Danny says that Gregor has white hair like the Guys in White, but the Guys in White are bald.
In the parking lot when Gregor kissed Sam, Danny had on a plain face, was standing up and was next to a purple car before the commercial. But after the commercial, he has a shocked face and he's crouching on a blue car.
When the Guys in White shot Danny at Amity Park Mall, Danny's ghostly glow was missing. After he landed in the parking lot, his ghostly glow was back.
Danny didn't need a dime to get into the bathroom. With everybody freaking out, he could have gone intangible and phased through the door.
Gregor wears his sunglasses at night for no apparent reason.
At the beginning, Gregor was wearing two earrings but during the episode, the number of earings he was wearing keeps alternating from one to two.
For a moment after Sam discovers Danny was spying on her, and Danny is talking to Tucker, the red part on his collar is missing.
Danny's hair is blasted askew by the Guys in White carrying a bazooka, but in the next scene his hair returns to normal.
Gregor: Hey, Same, you want to...
Sam: (interrupting) Whatever it is, yes!
Gregor: (laughing) His fly was down entire time! (more laughing) What is fly?
Tucker: (Talking about his ringing cell phone) I have to take this.
Sam: (Annoyed) So do I, apparently.
Gregor: This place is too crazy for me! I'm going back to Michigan!
Tucker: Don't you mean Hungary, Gregor?
Gregor: (Running away) My name is Elliot!
Mr. Lancer: Ah...the perfect way to spend lunch; Shakespeare by the pool, and dry white toast!
(The pool explodes)
Mr. Lancer: Hunt for Red October!
Gregor: (To Danny) Oh, by the way. Cool shirt.
Danny: Not too much red messing up the whole white thing for you?
Gregor: It totally works for you. I could never pull off such a look myself.
Danny: Really? (Short chuckle) Thanks!
Guy in White #2: (About Skulker) Target ghost obtained.
Guy in White #1: True, but his suit is hard-wired. If we can access it's database...
Guy in White #2: It may help lead us to our primary objective.
(An image of Danny appears on their computer screen)
Guy in White #2: The punk known as Danny Phantom.
Guy in White #1: (After his boss discovers his suit is filthy) Uh, did you know in Hungary, black is the new white?
Tucker: You think that "pssh" thing would help me pick up girls? (Sees Star & Paulina walk by; turns his beret around) Excuse me, ladies!
(Tucker walks off-screen; "Pssh" is heard, a scream, then a loud slap)
Sam & Danny: That's a no. (They laugh)
Gregor: (To Danny; about Sam) You like her more than just friends?
Sam: (About Gregor) He's not my boyfriend. I dumped as soon as I found out you were right about him being a phoney. Apparently, that is the only way a guy could like me.
Tucker: That's not true.
Danny: That's totally not true! There's a million reasons why a guy could like you. I mean, you're smart, you're fun, you're cool, you're pretty--(Cuts of abruptly after catching himself; Sam blushes) Why am I still talking? I am such a spazz. Still friends?
Sam: Pssh. The best.
Gregor: (To Sam) I like you, and I would like to go steady.
Sam: With me?
Gregor: Yes, you, and not your losing friend Tucker.
Sam: It's "loser."
Gregor: So you agree.
(Danny's on the phone with Tucker)
Danny: Anything to report?
Tucker: I bought a gory book at Skulk and Lurk, I shot two under par at the golf course, and Sam's got a kicking new surrond sound.
Danny: I meant about Gregor!
Tucker: Thanks for letting me tag along; hope I'm not in your way.
Sam: Of course not. You asked to tag along. (Starts yelling at nothing thinking Danny's somewhere) Unlike some people who'd better not be here right now!
Sam: (After learning of Danny's motives for spying on her) You think the only way a guy could like me is if he's in on some plot to get you? Ego much?
(Tucker is wearing his beret forward)
Danny: Would you wear this thing right?
Tucker: Gregor thinks it's cool.
Danny: Who cares about Gregor?
(Sam turns the corner)
Sam: Hey, guys.
Tucker: Give you three guesses.
Danny: (After waving to Valerie; Tucker has told him to let it go) Yeah, I know, but it's not easy. I mean, do you guys realize what it's like to like someone you can't be with?
(Sam spits out her soda)
Tucker: Do ya, Sam? Huh? Do ya?
(Sam tosses her soda towards Tucker's head)
Danny: (Spying on Sam and Gregor on their date while eating a plate of spaghetti) If they share a strand of that spaghetti, I'm gonna hurl!
Gregor: (In Nasty Burger; after seeing ghost fly by) A ghost?
Sam: Welcome to Amity Park!
Black Man in White: A prepubesant spector operating freely? Unacceptable!
Danny: Hey! I have totally hit puberty! (Reaches in his shirt and pulls out a white chest hair) See that? Totally a chest hair.
Gregor: (To Tucker) Shouting angrily into the sky? Very Euro-Goth.
Guy in White # 1: (To Mr. Lancer) The Purple back Gorilla research we traced goes back to an assignment YOU set back a while ago.
Mr. Lancer: And what makes you think I want to cooperate with the feds?
Guy in White # 1: Because ghosts pose a constant threat to your student body.
Guy in White # 2: And because we're with the government and have access to your tax records...
Mr. Lancer: What do you want to know and how fast do you want to know it?
Sam: (To Gregor) You're goth? But....you're wearing white!
Gregor: In Hungary, white is the new black.
According to the Guys in White, Danny's ghost powers are at a scale 7.
The name of this episode refers to how Danny temporarily betrays Sam's trust out of jealousy.
We learn that the Amity Park is not in Michigan; Gregor (Elliot) proves this.
Title picture: Gregor (Elliot)'s face with Sam and Danny in his glasses; Sam has tiny hearts; Danny looks jealous; Guys in White are flying next to Gregor (Elliot)
When the Guys in White shoot Danny, he does the defensive trick that Jack Plasmius did in "Masters Of All Time."
Look Hard: When Sam, Gregor & Tucker are at the Nasty Burger, there is no soda next to Gregor's tray. Right after the close-up on Tucker switches back to Gregor & Sam, there is a cup of soda.
When Danny defends himself from the missiles, he does the defensive trick Vlad did in "Bitter Reunions," where he made that shield.
It is hinted that Danny might think of Sam as "more than a friend" because every time the subject of Sam and Gregor is brought up, Danny gets depressed or angry. One that stands out is when Gregor and Sam kissed and Danny became really sad and declared that his life was "worse" now.
Apparently, the owner of Skulk and Lurk must have lifted Sam's ban from "Lucky in Love."
It is revealed that Tucker reads graphic novels, which are issues of comic books collected in a single volume.
Sam gets a new surround sound system for her home theater.
Sam being an Ultra-Recyclo Vegetarian resurfaces in this episode.
Opener: A tiny ghost comes flying by, then Skulker appears to capture it, and scare a man who was watching. Right after he attacks, Skulker is attacked himself by the Guys in White, who capture his ecto-skeleton. They decide to use it's technology and data to capture their prime target, Danny Phantom.
We learn that Danny's Body Hair (chest hair) changes to white when he changes to his ghost form.
It is shown that one needs a dime in order to use the restroom at the Nasty Burger.
Apparently, Jack and Maddie believe it's absurd for humans and ghosts to hang out and be friends.
Main Villain Bio: Guys In White: A duo of ghost hunters from a secret government agency. They first appeared in "The Million Dollar Ghost" as minor threats towards Danny. After stealing Skulker's ecto-skeleton, they have developed technology that make them more dangerous to Danny than before.
Apparently, Maddie and Jack don't belive there is any connection between Danny Phantom and Danny Fenton.
Apparently, Danny gets offended when people say he hasn't gone through puberty yet.
Look hard: After the theme song, while Danny, Sam, and Tucker are walking through school, you can see the two girls who helped pick up Danny when he fell down the stairs in "Beauty Marked."
Danny is again asked if he likes Sam, and again he stammers and doesn't respond.
Look hard: When the Guys in White are walking out the store in the mall they pass the Abyss store, in the window is a sign for a Fleecy-Tee sale. But this shirt should no longer be in the store, since it was mentioned in "Parental Bonding", that the shirt was discontinued.
At the beginning of the episode, Danny says, "You guys don't know what it's like to like someone you can't be with?" Then Sam spits out her drink. That can show her liking for Danny. Because she can't be with him. Then Tucker says, "Do you Sam? Huh? Do you?" That shows mostly that Sam likes Danny.
Jazz and Dash do not appear in this episode.
At one point during this episode, Sam seems to become confused with her feelings between Danny and Gregor.
Gregor kisses Sam in this episode, marking Sam's fifth kiss; the first being with Danny, second being with Dash, third being with Tucker and fourth being with Danny again.
At the end of the episode, we learn that Danny thinks that Sam is smart, fun, cool, and pretty.
Gregor's real name is Elliot and he is really from Michigan.
Danny doesn't catch a ghost with the Fenton Thermos in this episode.
1) Someone shouting at the sky (at Danny) & Gregor (thinking they're just randomly shouting at the sky) making a comment about it
2) Danny thinking Gregor is with the Guys in White
3) Someone saying what black and white in Hungary is like
4) Tucker wearing his hat backwards and getting himself hurt
5) Someone speaking fast and calling themselves a spazz when talking to someone they like
6) Someone going "Pssh"
7) The Guys in White calling Danny "prepubescent"
Danny is using his battle cry "Going Ghost" less and less during the series. He never used it in this episode.
One of the times Danny was fighting the Guys in White he used an ecto shield. This was first used in "Bitter Reunions" by Vlad. This was the first time Danny had ever done it like this.
Valerie must have gotten a promotion at the Nasty Burger because in "Life Lessons," she was in the Nasty Nat costume and now she's working the cash register.
Main Villain(s): Guys In White
If you don't count the Guys in Whites' picture of Danny, this is the fifth episode Danny doesn't appear before the theme song.
The Guys in White are the second people in the series to use taxes to get someone to trust them. The first was Bertrand in "Doctor's Disorders."
Title Screen Caption: "Double the romance!Double the terror!"
In this episode, it is revealed that Casper High has a pool.
Tucker's ringtone on his cell phone is a polyphonic version of the theme song.
This is the second time Skulker's real ghost form leaves the ecto suit.
We learn here that Danny has chest hair.
This episode is set chronologically before "Kindred Spirits."
A Match Made in Space: Name
The book shown, A Match Made in Space, is similar to the phrase, A match made in Heaven.
Book Author: Edward Gorey
Edward Gorey was an actual writer whose stories frequently delved into the whimsically macabre. They were usually short and fully illustrated, ranging from The Gashlycrumb Tinies - a book in which 26 children, each one's name starting with a different letter of the alphabet, meet their demise in a different way - to more serious, grown-up tales.
Gregor/Elliot: Wearing sunglasses when it's dark out
This may be a reference to the Blues Brothers movie, when Elwood says, "...it's dark, and we're wearing sunglasses."
Danny: If they share a spaghetti strand I'm gonna hurl!
This is a allusion of the movie The Lady and the Tramp, who, shared a piece of pasta that led to thier first kiss. Danny was expecting this to happen
Mr. Lancer: Hunt for Red October!
This refers to the book "The Hunt For Red October" by Tom Clancy which follows the adventures of a Soviet submarine captain and a CIA analyst.
Book: A Match Made in Space When in the Goth Book Store, The Book "A Match Made in Space" is shown. This is the book George McFly had written at the end of Back to The Future. This reference also seems to coincide with the fact that David Kaufman, the voice of Danny, played Marty McFly in the 1992-93 television series of Back to the Future.
Episode Title: Double Cross My Heart
The title is likely a fusion of the two phrases, "double-crosser" and "cross my heart and hope to die."
