I don't see Tenzin being completely down for more than a couple weeks because this dispute with benders killed his wife who had never done a criminal action in her life. He'll have moments of weakness remembering that he wasn't able to take care of her, but the longer he hides away the more painful it will become. If we skip an entire month, we'd need to fill in a ton of blanks as far as the relationship development of everyone else is concerned.

So: I vote one week, or at least no more than two. What about youuuu?
