My thoughts on this chapter:
1) bankai?!
2) do the outers have something to do with the shadow world that will appear "in 7 months" (I guess it's less now) or does crow came back in time, as well, or ... what the heck. I feel like Desir had mentioned something about the outers and the shadow world but I can't recall. (hehe, outers with inside info?)
3) oh yay, new brats students to break in.
On that note, they made it a big deal for crow to appear on the battlefield and then... time skip? What happened on the battlefield? Also that kind or lord or whoever that's an outer but sent a large force out, how did it play out? Or are they waiting for the bigbigbig shadow world to appear?
