Beetee absolutely does love Kadi but tries not to show it too much, because she's already enough of a terror. She pulls pranks at school like spiderwebbing his entire office with string or assembling a miniature particle accelerator in the janitor's closet. So he tries to be very Srs Bsns but doesn't totally succeed.

Kadi's actually a bit overwhelming for Eibhlin I think--where Rokia rolls with just about whatever Eibhlin proposes, Kadi pushes back harder than Eib's used to. So at first she's like "woah there, how do I deal with someone who won't let me be in charge?" but they figure it out.
