Summary
After the Young Justice heroes easily take out the H.I.V.E. while the Teen Titans make silly jokes, Robin makes the team become more serious.

Plot
This episode starts with the H.I.V.E. Five stealing radioactive tubes from a storage area, however the Titans arrive on the scene to stop them. Robin declares it is the final battle, and tries to give an intimidating speech. However, he keeps getting interrupted by the other Titans making farting sounds. He finally gets fed-up and orders the other Titans to stop, but they say he's too serious and continue with their silliness. Robin reminds them that they are the last line of superheroes, and asks if they can't be serious then who would be. Right on cue, some of the Young Justice Heroes fly in and easily take down the H.I.V.E., while the Titans watch in amazement. Aqualad attacks Mammoth with a water dagger, Miss Martian stretches out her hands to punch Gizmo and Jinx, while Superboy takes out See-More and Billy Numerous, which impresses Starfire.

After the H.I.V.E. get apprehended, Robin greets Aqualad and shows his respect for them. Aqualad halfheartedly greets him back, and asks to be excused, as there was an emergency in the SN-1885 quadrant. Robin nervously pretends his team should head there as well, however Aqualad mocks him by asking if it was on their way to "a pie eating competition". At the mention of "pie" Cyborg and Beast Boy come over and begin singing "I Love Pie", before Robin shoos then away. Aqualad then exclaims how the Teen Titans bring disgrace upon real heroes. Robin desperately tries defending his team, and states that even they did things differently, ultimately they both had the same goal of capturing bad guys. Aqualad looks over at Starfire and Raven, who break Jinx out of her manacles so they could go on another Girl's Night Out. Aqualad then declares that superheroes are supposed to teach important lessons about life. Robin sheepishly states the Titans also did so, but Aqualad jeers by asking if it was lessons like "books are dangerous", or whether "burgers or burritos were better". Robin protests that there is nothing wrong with being a bit silly, but Aqualad states the Titans couldn't be serious even for one second. Aqualad then ends the conversation and departs in disgust.

Back at the Titans Tower, Robin makes an effort to becomes more serious, and brings up his dead parents, much to the other Titans' shock. Starfire suspects Robin is acting this way due to feeling outclassed by the Young Justice Team, who she says are "real heroes". However Robin declares the Titans are real heroes too, only they had forgotten their true purpose due to spending to much time fooling around, even Raven. Raven denies this, but Robin reveals he knows what Raven had been hiding, and the scene switches to Raven doing a stand-up comedy routine with Robin in the audience unamused by it. Robin reaffirms that Raven isn't funny no matter how hard she tries, but he looks up to see all the Titans making silly faces. Raven tries to get Robin to admit they're a bit funny, but he angrily denies it, and says they could be so much more than their current two-dimensional state. Robin approaches Cyborg, and tweaks his curiosity by asking if his condition as a half-human, half-machine caused him to become conflicted over his identity. Upon hearing this Cyborg begins to think deeply and becomes more serious for a change. Starfire worries that being more serious could fracture the team, but Robin assures her that it would only make them stronger. Starfire still does not understand, to which Robin explains it is because she's an alien. The Titans finally agree to become more serious, and the "Serious Song" commences where all of the Titans undergo transformations into more serious appearances, including Silkie.

In the next scene, a computer display showing the time in 24 hour format, accompanied by the words "Breakfast time". The scene cuts to the kitchen, where the Titans indeed are eating breakfast in a serious fashion. Robin asks if anyone would like to sing a song about pie, but Cyborg says he can't as he is too conflicted to sing. Beast Boy also adds that he feels so emotionally complex, and Raven remarks that they should've gotten serious years ago. Robin is now satisfied that his team is no longer a disgrace. Suddenly, the crime alert rings, and the Titans gather around the computer to discover the H.I.V.E. Five are about to launch a satellite capable of destroying the world. Robin declares that they must be stopped or the world will be destroyed. Starfire embraces Robin and is about to tell him something, but he pulls away, saying there isn't time before ordering the Titans away with a very serious: "Titans, Go!".

The Titans gather at H.I.V.E.'s Arctic launch site, just as they're finishing preparations for their rocket. The Titans all notice and point out how dark it is, but Robin assures them that the night only made the situation even more serious. Cyborg contemplates using his cybernetic eye to see in the dark, but reconsiders as he's still strung on losing his humanity. Starfire tries again to tell Robin something, but he still brushes her off. Beast Boy then announces that it was an honor serving with the other Titans, in the case they don't return. Robin finally signals the Titans to attacks with the command "Show time!". The H.I.V.E. are about to begin their launch countdown, when the Titans show up and Robin orders them to stop. Gizmo is shocked by how serious the Titans look, but still taunts them before starts the countdown. The Titans briskly take down all of the H.I.V.E., but fail to stop the launch in time. Robin decides the only way to stop the rocket is using "serious firepower". Cyborg proceeds to transform into a gigantic artillery, and attaches to Beast Boy in Tyrannosaurus Rex form. The other Titans jump on top, and they unleash a massive laser burst that destroys the rocket. After their accomplishment the Young Justice team arrives. Aqualad is impressed by the Titans work, explaining they had come to clean up the Titans' mess, but there was no longer any need since the they had it under control. Robin points out that Aqualad had misjudged the Teen Titans, however Aqualad voices concern that the Titans had become too serious. However, the Titans have another "life and death" emergency to attend to, and they depart from the scene, with Robin feeling "this is only the beginning".

Back the Titans' living room, Robin is surprised that Aqualad said the Titans are "too serious", but he is dismissed by Beast Boy. Cyborg drank all of Beast Boy's orange juice, and Beast Boy demands to know why. Cyborg bluntly states that he was thirsty, but Beast Boy refuses this excuse because his name was on the carton. He finally declares that if he can't trust Cyborg with juice, he can't trust him at all, and Cyborg reciprocates the sentiment. As Robin attempts to defuse the situation, Raven urgently exclaims that her inner demon is feeding on their anger. Starfire cries from everyone's anger as the dysfunction reaches a climax as all of the Titans scream at each other, causing Titans Tower to explode. As the Titans all go their separate ways, Robin admits that, though he thought being serious would bring the Titans together, it has instead driven them apart. It seems the episode is about to end on a sorrowful cliff-hanger.

However, this scene cuts to the same computer screen from earlier with the printout, "Next week on Teen Titans Go!". The final scene shows all of the Titans back in the Tower, acting all silly again, while Robin ashamedly shakes his head.

Trivia

 * This episode aired one year after "Birds".
 * This is the second crossover episode of the series. The first being "The Best Robin".
 * This episode is the first one to have two previews available before the release date.
 * Aqualad technically breaks the fourth wall when he calls Robin out, as he addressed many of the real-life complaints by older fans that Teen Titans Go! was too silly and not as serious or mature.
 * Aqualad (Kaldur'ahm) is voiced by Khary Payton, who also voices him in Young Justice.
 * This is the first time Robin's parents have been mentioned, and it is confirmed that they are dead.
 * However, it is possible he is referencing Batman's dark, brooding nature, as Batman's parents are also dead.
 * This is the first time Raven has willingly joined in the other Titans' silliness.
 * It is interesting to note that, although Raven found Robin's jokes funny ("Uncle Jokes", "Hose Water"), Robin does not find Raven's jokes funny.
 * This is the first time ever that Starfire advances on Robin, while he pushes her away.
 * Raven's "serious face" changes throughout the episode, starting off with a prominent chin, before it becomes skeletal thin.
 * Beast Boy's "serious face" also has two variations with the first one occurring during the transformation during a one second frame at the scene were they show all the Titans singularly in serious form.
 * This is the first (and only) episode to show a "next episode" preview, even though it's a false one.
 * This episode is likely poking fun at those who complained about Teen Titans Go! having a much more light-hearted tone than the original series.

Continuity

 * This is the third episode to reference events from past episodes, the others being "Books", "Be Mine".
 * Aspects from several previous episodes are referenced in this episode:
 * Cyborg and Beast Boy begin singing I Love Pie from "Pie Bros".
 * Starfire and Raven free Jinx and are about to have a third "Girl's Night Out".
 * Aqualad also references "Books" and "Burger vs. Burrito".
 * This is the third time the Titans break up, the others being "Super Robin", "Staring at the Future".
 * The Titans being silly on the couch is very similar to what they did in "Más y Menos".
 * The location where Raven is doing her stand up routine seems to be the same one Robin was at during the "Uncle Jokes" song.
 * The Titans' "serious faces" are similar to Robin's handsome face in "The Mask", as well as Beast Boy and Cyborg's faces in "Caramel Apples" when Robin gives them inspirational speeches.
 * This is the second time Cyborg has been concerned over his humanity, the first time was in "Real Boy Adventures". Technically it was brought up in "Tower Power" and "Man Person", but on those occasions he seemed to enjoy his loss of humanity.
 * This is the second episode of Season 2 to feature See-More being the driver, the first being "Money Grandma."
 * This is the second episode to use different animation other than live-action animation, with the first being "Dreams".
 * In the episode "Books", the Titans make similar faces to their serious ones after finding a comic book.

Errors

 * The H.I.V.E. were able to launch their rocket despite being captured by Young Justice.
 * Superboy is able to fly, despite being overwritten by Lex Luther's Human DNA.
 * It is unknown how Aqualad would be aware of the events that happened in the episodes Books and Burger vs. Burrito, as both of those things took place within the Titans Tower. And even in instances where they were outside, spectators would have no idea what was going on unless they were close enough to hear what the Titans were saying.

Running Gags

 * The Titans engaging in silliness.
 * The Titans being serious.
