"Babysit Klee?" Kaeya asked for the third time you explained it.

Albedo asked you to babysit Klee since he had somewhere to go, Jean was busy too, so Kaeya was the last option to get help from.

Well, although Klee was just a kid, you couldn't handle her yourself. She's quite... deadly.

"You need my help, huh?" He once again spoke, but now, in a smug tone.

"It's unusual for miss 'I-can-do-anything-so-I-don't-need-your-help' to ask for assistance." He added with a smug smile.
