I'm waiting for more detailed spoilers too, but nothing. D:
It was a surprise to read that Shunsui need help immediately after Stark's release. D: I don't want him injured, noo. *cries* If he is injured, I expect judicious clothes tearing to make up for it, Kubo! Okay, then i would forgive him. XD
I hope we see their bankais soon, it's about time!
And i'm happy to see Jyuu's helping him, i knew they will fight together. :3
