Apparently, Technus survived the satellite explosion in "Flirting With Disaster". (edit) The Fenton Portal is destroyed when Danny used it to make him human again. The portal overloaded and then exploded. (edit) This is the first time Danny and Sam have kissed with Danny still in ghost form. (edit) This is the third time in the series that Danny decides to get rid of his ghost powers. The first time was in "Identity Crisis", and the second one being "The Ultimate Enemy". (edit) This is the third time in the show and the first time in the season that Danny sounds heroic. The first time was The Million Dollar Ghost and second was Identity Crisis. (edit)

Danny:(To Sam) Could you pass me a corndog?
(Sam angrily shoves a corndog in Danny's mouth and storms off)
Danny: Sam, you don't have to be mad, the corndogs are made of tofu!
Sam: It's not the corndogs, you're not you anymore. You're just... a normal kid, and a selfish one at that.
Danny: How am I selfish, because I'm protecting the ones I care about the most.
Sam: Don't you get it? You had a chance to change things, a chance no one else had, but now you're just... one of the crowd again.
Danny: What's wrong with that?
Sam: Everything, you got to fight ghosts while other kids fought acne and you don't seem to care too much what you gave up.
Danny: I care, it's just that I care about you and... my family more.
Sam: When you had your powers, I knew this town was protected from evil, but now... who knows where we're headed.
(You see the Masters Blasters getting a citizen to pay for their work)
Sam: I'll always be your friend Danny and I'll always be there for you, but I can't live my life just sitting on the sidelines, I'm surprised to see that you can.
(Danny takes a bite out of his corndog, then gags and spits it out)
Danny: Tofu! (edit) (Danny is considering getting rid of his powers)
Jazz: Danny, what are you thinking?
Danny: Give me one good reason I should keep my powers.
Tucker: You're the target of hundreds of evil ghosts! Oh, wait that's bad. I'll get back to finding something that rhymes with "Phantom". (edit) (After Danny gets rid of his powers, he faints)
Sam: Danny, can you hear me? How do you feel?
(Danny places his hand on Sam's and opens his eyes a little)
Danny: (Weakly) Human. (He faints) (edit) (Danny and the others fly into the ghost zone through a portal in the mouth of a billboard)
Tucker: Now I know how my chili-cheese fries feel! (edit) (After Danny gets rid of his ghost powers)
Tucker:: Did he just do what I think he did?
Jazz: You mean step back into the Fenton Portal, remove his ghost powers, and revert his DNA profile back to that of an average human?
Tucker: I was going to say go un-ghost, but that works too. (edit)

One of the news articles reveals that Danny has a Florida-shaped birthmark, accompanied by a picture. But the birthmark is never visible any time his uniform is blasted off. (edit) Throughout the episode, Vlad goes into space in his ghost form with an air helmet. But at the end, he isn't wearing one, and is still alive. Does this confirm that ghosts don't need preservers in space? (edit) Look Hard: In the scene in which Danny tried to punch Vlad in the Fenton's Ghost Lab, Vlad grabs Danny and picks him up by the shirt. When his legs appear, you will notice the white ghostly outline on his legs. (edit) Look hard: When Danny says to the ghosts after they are freed from the net, "If ours goes, yours goes too. I have a plan.." you can see two medusas. (edit) Apparently when Danny re-activates the Fenton Portal, some Ghost DNA is left in his streak of white hair. (edit)

The Tower that was use to make the planet intangible is based on the towers used in the DC Comics' limited series, 'Crisis on Infinite Earths.' The towers were placed on various earths of different dimensions and were used to merge all of the earths into one. (edit) Danny & Sam: "Come back scene".
The scene towards the end of Phantom Planet, where Sam gives Danny his ring back and tells him to promise, is very similar to one in a video game by Disney and Square Enix, Kingdom Hearts. In the Kingdom Hearts scene, Kairi gives Sora her good luck charm and tells him to promise to come back. They also both take place before the male lead heads into some world-threatening situation, either Sora going to fight Ansem, or Danny helping stop the asteroid. (edit) Episode: Subplot.
The storyline is similar to a Kim Possible episode at the end of the third season "Team Impossible". A team of three agents try to get Kim's career out of busness, beat her three times she tried to save the world, Kim tries to outsmart them and then thinks she should quit, then ends up beating them anyway. (edit) Danny: Give me one good reason I should keep my powers?
This is similar to Spiderman 2. Peter's powers disapear for some reason, so he becomes a normal teenager again and when the world is in trouble, he gets his powers back. (edit) Danny: Atomic batteries to Power. Turbine to speed.
When Danny starts powering up the Fenton Jet before going through the Ghost Portal, he says, "Atomic batteries to Power. Turbine to speed." This is the same startup sequence used by Burt Ward as Robin in the 1966 live action Batman TV series. (edit)
