You're killing me already! *sobs on the floor*

I think it would be better if Tenzin did cross the line first. Lin wants to respect him, his memory of Pema, and the kids. And I know by then she and kids will be close and used to each other, but part of Lin will always feel like an outsider when it comes to happiness. I just hope by then, she lets herself accept it without trying to talk Tenzin out of it. I know from experience that the more you like someone and want a future together, that when it actually happens, it throws you off and you find yourself doubting how real it is and if the other person has wanted it as much as you've dreamed about it.
