You know that show on cartoon network errrr teen titen or something i have a question about that?

well i don't really watch that and i guess when i terned the tv on (after a long day) it was on cartoon network (just a few seconds ago) and i saw it and i just got in to it. it was an episode where some girl named terra (at the end) she terned to stone and the goth girl said " well figure out how to reverse it. " and the adult said " ya someday" (after goth girl said well figure out how to reverse it.) well i am wondering if that some day was well already happened where they tarn her back to a person well let me know by!
