Felix makes a few mistakes this time, because he's listening to her too much and it's distracting him from the focus he needs to get this right. They're small, though, and few, and with Annette singing along it feels more right. Practicing it without the singing made it sound sort of empty, even when he sang along under his breath to make sure he was getting the timing right.

But this... This is perfect.

His mind is already turning to the places where he could have done better when she's doing her best golden retriever impression, and his brows lift, but he nods.

"All right. I need to work on the muscle memory so I don't let your singing distract me."

(Felix, that's not why she wants to do it again...)

...then he realizes what he's said and his face flushes. "Um...because I'm not...used to coordinating it with someone else. Is why I got distracted. That's all."
