Hi Chibi Halo!
Yes, I – Da7e – do think that. I think I mention it out-loud on Episode 3 of the podcast, but the way Amon knocks Korra out before she flashes back looked odd to me. It’s my opinion that Amon is responsible for triggering the flashback and that he did so to accelerate Korra’s training.
I think Amon plans to defeat only a full Avatar, which Korra isn’t at the moment.
Here’s a picture of a Chibi Halo 2 ODSTs.
