Apparently, Cyborgs age faster than everyone else. Cyborg would have only been 30-something, but looks like he's 60.
Beast Boy's transformations: Frog, turtle, bear, lion, seal, pig, chicken, meerkat.
20 years in the future, everyone has gotten either fatter or taller, though Raven stayed relatively unchanged.
Since Robin in the Teen Titans follows the same path as the Robin in Batman Gotham Knights, eventually becoming Nightwing in the future, Robin is actually Richard "Dick" Grayson (which is confirmed in #47 of Teen Titans Go).
The helmets on the guards frozen by Warp alternate appearances from the time where they are frozen to the shot of them twenty yearts later; the guards frozen by Warp clearly have full face helmets on, but in the future, the mouths of the frozen guards are visible through entirely different helmets.
Nightwing's lair has a display stand of old former costumes, just like the Batcave. In the establishing scene, we see grinding gears, just like in Slade's hideout.
After the future Teen Titans defeated Warp, why didn't any of them thaw out the policemen that were frozen in time? They were completely forgotten both by the present and future gang.
When Warp freezes the Jump City police, they are wearing the same helmets in "Divide and Conquer." When it shows Warp 20 years later attempting to fix his vortex regulator, the policemen are wearing different helmets.
Throughout the entire part of the episode where Starfire is in the future, Raven's eyes are always glowing, except after the scene where Starfire is asking if this was really their future.
Raven's age, accent, or size hasn't changed at all in this episode.
The cave where Nightwing takes Starfire looks almost exactly like Slade's old hideout from "Apprentice" pt. 1 and 2.
If Starfire wasn't in the past to help stop the end of the world ("The End (1)," "The End (2)," & "The End (3)"), there is a very high chance there wouldn't be a future to go to! Really, when you think about it, the powers they got from Raven would be most likely less powerful, and there would be a big difference in the way they'd have to do it.
Without his time machine, Warp gets older. Shouldn't he be getting younger, as he went BACK in time, not forward?
When Raven touches her beeper, her clothes are white. When she appears to fight Warp, her cloak is white, and her clothes are black.
Future Cyborg: I can tell you where to find BB and Raven.
Starfire: And Robin?
Future Cyborg: We lost touch a long time ago. If you're looking for him, you're on your own.
Future Raven: (Slowly, menacingly) Nobody hurts my friends!
Future Beast Boy: (To Starfire) Look, after the Titans broke up, I tried the whole solo-hero thing, but I got my butt kicked, a lot. So, now, well... I am in show-biz now...
Warp: Valuable in the past, priceless in the future!
Robin: But for the present: keep your filthy hands off it!
Warp: You cannot defeat Warp! I am from the future!
Cyborg: (After he shoots Warp) Boo-ya! (Warp is unharmed) ...Huh?
Beast Boy: Well, Raven's not giving me back my nail clippers!
Raven: How ELSE am I supposed to keep your toenails off the coffee table?
Starfire: In my world, Rekmas means "The Drifting," the point in which close friends begin to drift apart... and their friendship begins to die...
Robin: We're not going to drift apart, Star. I promise. We'll all be friends forever.
Future Beast Boy: (Looks at Nightwing's long hair) Dude, that is SO not fair.
Starfire: (To Warp) You have also become old.
Warp: (Annoyed) That's what happens when someone steals my vortex regulator!
Cyborg: (Arguing with Beast Boy over the GameStation) Come on, Beast Boy! Gimme that thing!
Beast Boy: DUDE! I'm in the middle of a game, Cyborg!
Cyborg: Yeah, my game 'cause it's my turn!
Beast Boy: Give me the controller!
Cyborg: NO! Give it to me!
Beast Boy: IT IS MY TURN!
Beast Boy: You mean I'm going to be bald?! (Tears some of his hair out)
Future Beast Boy: (Looks at a baby Warp crying) Okay, I am NOT changing any diapers.
Robin: So, Nightwing, huh?
Robin: (To Cyborg & Beast Boy) KNOCK IT OFF! I can't work with you two acting like idiots!
Raven: Great, Robin. More yelling will definitely stop all the yelling.
Nightwing: It's good to see you again.
Nightwing: I haven't used that name in a long time, they call me Nightwing.
Future Cyborg: Yo! Who's up here blasting my - Star? (Drops his weapon) Starfire, I don't believe it. You - you haven't aged a day.
Starfire: Cyborg, what has happened? Why are you -
Future Cyborg: Old? Well, that's what happens to folks when they go away for 20 years.
Cyborg: (To Beast Boy) You're gonna pay for that you little grass stain!!!
Raven: So, is it too late for this festival of friendship thing?
Cyborg: HAPPY BLORTHOG!
Beast Boy: I thought it was Blort-hog.
Raven: (Getting blown by Cyborg's shouting) I feel like a wind chime.
Starfire: Raven? Raven, it is I, Starfire, your friend!
Future Raven: (Slowly) No such thing.
Starfire: Please, Raven, I -
Future Raven: Just another figment. Don't even look.
Starfire: You must listen! I am here because I'm -
Future Raven: I'm never coming back! Go away! (Moves away from Starfire) It has to go away. Just like before. Just like all the others.
Starfire: Your mind... without friends you must've - (Starfire tries to touch her, but Raven blocks it)
Future Beast Boy: Wait... these bars aren't to keep me in, they're to keep those maniacs out!
Raven: Robin? Could the music be any louder? I can still hear myself think.
Starfire: (Holding the Clock of Eternity) History said it disappeared... but history was WRONG.
Robin seems to have grown massively in terms of height. Based on that and several of the character animations, we can assume that at the present day, Cyborg would be probably 6'5-6'6, Starfire 5'11, Robin 5'7-8, Raven 5'4 and BB 5'3.
Nightwing looks a lot like Aqualad in this episode.
Based on the appearance of the future in this episode, it is factual that the Titans, without Starfire, defeated Trigon in "The End (3)."
If you watch carefully, the battle sequence against Warp was almost the same, except that Warp's attacks fail, and the Titans attacks generally hit. Note that:
1) Warp fires a beam at the banister the Titans were on
2) Warp throws back a starbolt Starfire threw
3) Robin/Nightwing deflecting a beam with his bo staff
4) Beast Boy charging at Warp in lion form
5) Cyborg firing the cannon at warp's chest and proclaiming "Boo-yah!" after, and finally...
6) Robin/Nightwing and Warp throw projectiles at the same time and they collide
In the comic book series, Warp did not have the ability to travel through time. Instead, he was able to create dimensional warps from one place to another, like teleporation. He was also a part of the Brotherhood of Evil in the comics.
Villain Debut(s): Warp.
Beast Boy says that after the Teen Titans disbanded, he became a solo superhero, yet in the comics, he joined Titans West, and later Titans L.A. under the name of Changeling.
Opener: Starfire awakes at the tower to celebrate her Tamaranian holiday, Blorthog, with the others, but they ignore her and continue bickering with each other.
When the Titans battle Warp for the first time, the battle music they played was a remix of the battle music from "Apprentice (2)."
It makes sense that Cyborg is the only Titan who lives in Titan's Tower after the team split up, since it's his father who built it.
Future selves of the Titans:
Robin: Nightwing, still crime fighting. Long hair, more gadgets. Fights with tonfers.
Cyborg: Aged. Battery-powered. Can't leave the tower. The "Hey, you kids! This is a private junkyard! Getcher own fender" old protective guy.
Beast Boy: Carnival attraction. Bald. Laughingstock.
Raven: Has gone insane. Is in the "Padded Cell" type room. Very, very seclusive. Wears a white robe.
In this episode, White Raven is shown, yet in the episode "Nevermore" White Raven is a mixture of all sides of Raven's personality, and here White Raven is the future version of Raven.
The Nightwing presented is closer to the Batman Gotham Knights version than the comics version, the nightwing bird on the chest and long hair being the primary similarities. The Batman-like utility belt and metal gauntlets are unique to this version of Nightwing.
Blorthog is a Tamaranian holiday that Starfire celebrates, it is a festival of friendship.
Kids' WB! airdate: October 2, 2004.
In the beginning, you can see that Starfire has a Mumbo alarm clock.
Beast Boy tells Starfire he's in show-biz now. In the comic books, he actually worked as an actor, playing the role of an alien in the TV series Space Trek 2022, until it was cancelled.
The Dark Knight Returns
The design of the kids watching Beast Boy perform in the future is an allusion to the "Mutant Gang" kids from Frank Miller's The Dark Knight Returns.
Costume: Under Glass
The way Robin protects his original costume is similar to the way the Power Rangers Zeo protect their Mighty Morphin' Power Rangers costumes.
Robin's Uniform: Jason Todd
The way Nightwing guards his costume under a glass is the same way Batman keeps the costume of Jason Todd, the second Robin.
Clocks: Yellow Submarine
When Starfire and Warp are flying through the portal in time, the clocks are just like the ones in Yellow Submarine.
Episode Title: How Long Is Forever?
The title is a reference to a story by sci-fi author, Philip K. Dick.
