They didn't have time, I guess. But if they didn't have time to make a convincing romance, they should have focused on friendship building. Korra's Team Avatar is dogshit compared to the old group. And we still don't know what the fuck happened to Sokka, and Suki didn't get an appearance either. The fuck, man. And Ty Lee! I LIKED TY LEE DAMN IT!

It won't be an evening at home then. A walk through the park? Something light, where they can get some air and privacy. With so many people going to the game, the park may be nearly empty at that time of night. And like you said, they catch wind of the attack and race there to check on the others.

Oooh. Do you want to reveal it out of Asami's temper being flared because of Mako? Should she burn him on accident because he didn't expect it (and neither did she)?
