*sigh* I'm on the road right now, but If you go through the posts I made and look at the text in bold, it'll answer your questions.
I'll have Sagisō respond once I get home, though I'm sorta conflicted on how Sagisō should react. Since Kai is waiting for the team mates to respond, Sagisō could praise him in the way one would reward a pet, but it'll no doubt devolve into a fight right there on the spot and Sagisō isn't that condescending so it's also out of character...
Still weighing the options for other possible responses.
