It's weird that he saved his past self... like, how can your future self save you, if you can't get out to become your future self? I'm sure that there is a weird theory to justify it, but it seems off..
I gotta say, this arc does flesh out Kon as a character..

I'm wondering how long this arc still has to go.. the manga can't be far enough now, right?
Luckily this arc has this "we're powerless" vibe to it, like with the last parts fo the Aizen arc.. Even the captains realised they were too weak and got in serious mode when it comes to training.. I'd love to see a few episodes of that..
