She doesn't make very many mistakes, actually, though she does make them. She had her warm up, and it was even on a song that's based on this one, and she is very much trying her best. It's extremely stressful, though. She is probably the most anxious he's ever seen her, even beating out when she first arrived and literally feared she was about to die. They are not following the (read: her) standard piano playing procedure!!! Usually she'd read over the whole thing and maybe quickly practice the hardest parts before putting it all together instead of just, just. This!!! Duet with a guy who knows this song like it's his own heart, because in a way it kind of is, no time to breathe you're in the deep end and and and and.
It's fine. This is fine. She does not need any redos, she is fine she will make her damn tutor proud and she will awkwardly fill in for this lonely man's twin and if she flubs a little then then then it's his own damn fault, okay!
When the song is concluded she lets out a breath she didn't know she was holding. In sort of a nervous whine. She eases up from her hyperfocus to look at him and. Yep he's. He's crying. Um.
