In Aspirations, I felt bad for the Gang when Sedusa said that she was using them and I felt so bad when Ace had a tear run down his face. It's pretty obvious that Buttercup still hasn't gotten over what happened in Buttercrush. She can deny all she wants, but she wants to be with Ace 'cause she loves him!
Yeah...true 
^w^
^w^I remembered a few years ago on YouTube that there was a video of Buttercup/Ace and that it shows Buttercup singing "I Won't Say I'm in Love" from Hercules. She doesn't actually sing it, but the song form the movie plays and some videos of her with Ace play.
Yep.
