I don't think Asami would want to intrude on whatever verbal lashing is taking place so I'd assume she'd pull Mako into the kitchen before he tried to do what Korra did, was stick her nose where it shouldn't be to begin with. I assume Bolin's speech is gonna have to do with her stepping up and standing on her own two feet, being an adult, the leader the city and world expects from her, and that while he supports her, he doesn't want to be around just to give her a boost. And that she violated Tenzin's trust in her and that Tenzin has every right to be upset with her and that she should have done the right thing and left or spoken up sooner, than remain in hiding. And he'd probably encourage her to go out more and make friends, see parts of the city and help give people hope, etc.
