Bolin hopefully is more manly and less oblivious by that point so he can shut Opal down himself. Ha.

That gives me the most interesting of images. XD I assume Meelo will volunteer as Robin or something and the adults will insist he not. But if there are more air benders, Tenzin can be training them while Lin does tend to the city and visit Tenzin and his young wards. She'll be so proud and happy for him. But also for Aang cause she got along with him.
