Seriously, Meiling should get a kiss from Sakuya and a raise on her pay from Remilia, for that.

On one hand, you got the fact that Sakuya understood that mess that Meiling got into, because of that she thought of her as a good guard.

On the other, after Meiling's "joke"... yeah, she thinks that Meiling is a very good guard. "Too good" for a guard.
