It’s the episode in which the gang goes to Tamarand because Starfire suddenly announces she’s BETROTHED. As you may have guessed, Robin calmly flips a shit for most of the episode.
It turns out, however, that even though Starfire’s sister, Blackfire (yeah, I know…), told her that she must marry a gross alien in order to save her planet, it’s all a devious scheme!
The Titans and Starfire (who kicks some butt in this episode) prevail and Tamarand is saved. And Robin’s heart is not broken.
The End.
(They had some very Disney princess moments in this episode for Starfire… I mean look at that balcony! It’s totally the one from Aladdin!)
