I love it but I hate the fact that Kanan and Mari don't seem to be into each other. Like, what's the point of a poly relationship if you're not gonna be all over each other?
Well I think its an easy explaination here.
And that's Mari and Kanan wanted to make Dia feel better, they'd probably be more over each other, if Dia was feelibg better.
Also, seems Mari didn't get to do her usual foreplay, since Kanan told her to drop the teasing.
