[Lapis hardly ever stopped by the hotel unless Steven was there so if she had received an invitation she didn't know about it.
So she happens upon the concert purely on accident, but stays when Connie begins to play. She didn't know much about human music, but this was... nice. Especially the sadder notes.
She stays even after Connie starts packing up, standing closer to the tree. It's a little before most everyone has left that she speaks up.]
