lol I don't think Keigo is gaining some powers, though I thought the same originally. Matsumoto was messing around with him anyway.

As for what Hachi said to Inoue about a few pins being missing, he could have been talking about how two spikes should be there for Tsubaki, rather than there being more little critters.

And I also think some Espada are due for promotion after what happened to Grimmjow. Unless of course Grimmjow has the same regeneration ability as Ichigo, which seems unlikely at this point.
