This is the 13th episode of the series, and the name of the episode is "13". (edit) We see Sam's cat purse for a second time. The first time was in "Parental Bonding." (edit) The name of the episode comes for the fact that 13 is a bad luck number and Johnny 13 has the power to create bad luck. (edit) This marks the first time Danny's ghost sense goes off while in ghost form. (edit) In this episode, Jack creates an invention called the "Fenton Genetic Lock" and he says that the only way to open the Fenton Portal is for someone in the Fenton family to place their thumb on the lock. However, the lock was destroyed by the end of the episode. (edit)

Sam: (To Danny) If you need us tonight, we'll be at Tucker's, darkening his outlook on the world. (To Tucker) Won't that be fun?
Tucker: Yeah. It'll be... wait, what are you gonna be doing at Tucker's? (edit) Sam: (Referring to being a techno-geek) So, maybe your first thing was your best thing.
Tucker: Yeah... (Suspiciously) Hey, you never really wanted me to go Goth, did you?
Sam: Duh. Goth's my thing. (Holds up PDA) And I believe this is yours.
Tucker: (Takes PDA and kisses it) Oh, baby, I missed you! (edit) Concessions Kid: (To Tucker & Sam) One super large popcorn. (Gasps; to Tucker) I know you. You're Bad Luck Tuck.
Tucker: (Takes popcorn) And you're Minimum Wage Stan, but you don't hear me broadcasting it. (edit) Danny: The weirdest part is my parents and I were actually on the same page! I'm not like them! Am I?
Sam: Let's see. You're stubborn, overprotective, your last name's Fenton, and you hunt ghosts.
Tucker: Only thing you're missing is the hazmat goggles and the wonder gut. (edit) (Jack is trying to open the door using brute force)
Maddie: Jack, calm down. Try being a little more gentle...
(Danny & Johnny 13’s Shadow phase through the door; Maddie turns the lock slowly; door falls off its hinges)
Maddie: See?
Jack: Well, hey, I loosened it! (edit)

It is hinted that Danny can take off his costume when he says, "Hey! Easy on the ghost ink! I just got this suit cleaned!" It is confirmed later in "King Tuck" that it can be taken off. (edit) Near the end of the episode, Jazz has on the ring and Kitty & Jazz have switched places. When there is a close-up of Kitty, she has no pupils. (edit) When Dash answers Kwan while he is mimicing Tucker at the carnaval, Dash's eyes have no pupils for a few seconds. (edit) Tucker’s bee stings are gone in the next scene where he, Danny, and Sam are walking home from school until Danny’s ghost sense goes off and spots Jazz riding with Johnny on her motorcycle. (edit) Johnny doesn't have a ghostly glow until the end of the episode. (edit)

Johnny's bike: Appearance
Johnny 13's motorcycle seems based on a Harley Davidson motorcycle. (edit) Johnny 13: Shadow

The Shadow's power of everything he comes in contact with breaks, is similar to Teen Titans villanous Jinx who also gimmick is bring bad luck. (edit) Johnny 13: (Appearance and Name)
Johnny 13 may be based on Ghost Rider, who's powers including a gravity defying motorcycle (and the first Ghost Rider's real name is Johnny Blaze). (edit) Episode Name: 13
The episode's Title "13" refers to the number 13. the number 13 is associated with bad luck. (edit) Ghost Figure: Appearance
Watch the two brief cameos Ember has. Standing behind her is a figure that, white cloak aside, looks remarkably like the elephant-nosed spy from Star Wars who gave the location of Luke, Obi-Wan, and the Falcon away to the Stormtroopers. (edit)
