Yiddy - To be honest, I don't know for sure. I still haven't finished watching Part 2 in the anime, and I don't remember seeing it in the manga (which wasn't nearly as stylized). I just scalped it off of 4chan.
In regards to Nell, I'm sick of waiting for her to do something. There's a chance it might happen with Noritora, but Halibel and her Fracciones could easily step in too. So I'm just going to wait for Kubo to surprise me.
