Sure, Flynn doesn't realize he is appealing in many ways to people so he will definitely be like: uhhh? time to fight?

It's sure to be a fun time. Also, Flynn works well with just about anyone here, but in his own world he's just called an upstart knight for a long period of time. Now he works with the Emperor closely so no one really says anything anymore.

He likes Hijikata though, he reminds him of a certain someone.
