Sing a song.

"Sing me something," you tell her.

"But... but I can't sing!"

You shake your head. "All gypsies can sing. Come on, indulge me. Sing me The Summer Rose, it's my favourite."

She's visibly **** to draw any more attention to herself, but she's also under magical control, so she can't really stop herself from serenading you with a cracked and warbling version of The Summer Rose, an old ballad about a pretty but foolish princess who is tricked by a goblin into riding seven times around the town without any clothes on. You've always liked it, and a few times you've made people re-enact it. When she gets to the lyric about how the princess' cheeks were red as a summer rose she blushes and folds her hands between her legs, drawing a laugh from the crowd. She shoots you a dirty look and soldiers on with the ballad as bravely as she can.

Pretty fun. What else could you have her do?
