He needs a long chapter or two conversation with one of the captains where they basically stand at the door of his cell begging for his help and he does his best Anthony Hopkins impersonation, sans the fava beans... *slurp-slurp*

Nel: Unlikely. For one, she should already be right there. Her (re)appearance would be a huge letdown. Also, no reason for her to pull sword on Urahara.

Random new character (or random old character who should be dead/not there): Unlikely from a storytelling standpoint, but always possible with Kubo. Right before the end is always the best time to (re)introduce more characters for Ichigo to eventually outshine.

Random Zero Squad Member: NFW. I am convinced we will never see any Zero Squad Member. We have been trolled. The Squad is a lie.

Halibel: IN ICE PALACE LOCKED UP

Isshin: Unlikely. If Kubo hasn't forgetten about him, he should be back in the real world trying to get Ryuuken to get off his fat Quincy ass and finally do something in this series. Also, no reason to pull sword on Urahara. For that matter...

Either Ishida: Nope. Slashing people in half is just not their style.

Ulquiorra: Nah, he's down in Hell watching Twilight for the 9001th time...and probably enjoying it...

Grimmjow: Even chance. Stealing Urahara's kill like that (and denying us the chance to see Ol' Cloghat use Chad and Orihime as bait while he lines up another snipe) is right up Grimmy's alley, as is the threatening move toward Urahara. Of course, it really wouldn't make much sense if it is him, since none of the remaining ex-Espada, other than maybe Halibel, should have been able to one-shot this guy without going Resurreccion, but that's never stopped Kubo before. On a personal note, I've always thought he was wildly overrated, so I hope it's not him.

Gin: Better than even chance. Likely, even. Random bisection: check. Attack out of nowhere: check. Causes captain-level shinigami to shit bricks on demand: check. Yeah, sure, he's supposed to be dead, but we're in Hueco Mundo. Where was he going to go? Detroit?

Fixed bolded
It is soo Grimmjow
