Starliar

"Starliar" is Teen Titans Go! Season 1, Episode 9b, and the 18th overall episode of the series.

Summary
When Starfire is the only Titan invited to the Titans East Annual Dance Party, Beast Boy teaches her how to lie so that she can spare the other Titans' feelings, but her lies turn all of the Titans against each other. Meanwhile, when Starfire forgot to feed Silkie, so he goes into a feeding frenzy and entered each of the Titans' rooms and ate their stuff.

Plot
Beast Boy, Cyborg, Raven, and Robin are all practicing their dance moves for the upcoming Titans East party. When Robin asks what time the party starts, Raven suggests checking his invitation. However, the Titans realize that none of them were invited to the party. They find this odd because they were the life of the party last year, at least from their perspectives. This leads to a flashback of that time where they actually ruined the party in multiple ways, which include accidentally hurting people and playing spooky music that freaked out the guests.

Starfire reveals to Beast Boy that she was, in fact, invited to the party, and plans to inform the others of her popularity. Beast Boy knows this would hurt their feelings, so he tells Starfire to lie to them. She doesn't understand lying, so Beast Boy tells her how to do it. He claims that as long as she winks, they'll know she's just kidding. This of course, is not true.

Starfire then lies to the Titans. It all turns out good until the lies go wrong, and the rest of the Titans get mad at each other. So, Beast Boy and Starfire must then choose between going to the Titans East party, or admitting to the Titans that they had lied. Beastboy and Starfire decide go to the party, under the assumption that everything will be fine. As they're dancing, you can see sadness on Starfire's face, showing that she seems to feel bad about lying to the other Titans.

When they come back, Cyborg, Raven, and Robin were seen fighting with each other brutally, and had destroyed much of the Tower. They continue to fight until Starfire tells them to stop. Starfire admits to the Titans that she lied, and they forgave her and each other. Starfire feels so bad, that she says she will leave the Titans because of her actions. Robin stops her from doing so, dismissing the trouble she'd caused. The episode ends with Starfire winking at Beast Boy, after telling him that she meant everything she had said. This clues in that Starfire was possibly lying about being sorry in the first place.
