...Season 4, episode 62. titled, "Go! ". They also 키스 in the movie, "Trouble in Tokyo", but that doesn't count as an episode! (plus ROBIN X STARFIRE FOREVAH ^_^)
oh yea! and she learns any language through lip contact, so thats how she learned japanese in trouble in tokyo. But they do 키스 out of 사랑 in trouble in tokyo
Starfire kisses Robin to learn English, in the episode GO! They 키스 in Trouble In Tokyo, at the end, and finally become an official couple. In the GO! version, they don't kiss, though in the episode 'Dreams', Robin dreams of it. In the episode 'Puppets, Whaaat?' Robin makes the puppet of himself and Starfire 키스 three times.
Yes, in "Go!"(Episode 62) they do but that's only because Starfire needs to learn English. But in Teen Titans: Trouble in Tokyo (the movie) they 키스 after the battle with Brushogun's main ink monster.
