Yikes, things are starting to get trickier... I think that after a week Lin could get Tenzin back up to speed and then the case of new benders is emerging, and she can reason with him about the case of benders being afflicted and normal people getting them, believing they're strongly related. We CAN say that Republic City is essentially rebuilt due to the efforts of Asami's company and the benders/nonbenders working together. After a week of time I think Asami should reveal her ability before Borra and Masami go their separate ways. This gives Korra and Bolin something to think and talk about while they blow off some steam at the stadium, as well as Korra getting to the point where she wants in on the investigation with Lin and Tenzin since this is going to involve the Avatar eventually. I think this should be Mako and Asami's second or third date, there's no chance they haven't gone out again after the amazing evening they just had. Korra will have positive feelings about it because she likes Asami, but with Bolin will likely wonder why they wanted to keep it from them that entire week. So I'm thinking Lin and Tenzin/Grandchildren said goodbye to Katara, and then the children head back inside while Lin talks to Tenzin about the case since he's ready to continue. The Borra Masami group we can say either already revealed Asami's gift and are talking about it, or already did and are now at the stadium/date.
