After have watched episode 111 of the anime, there are few things that keep on bothering me.

Spoiler:

Comparing GF's Arrancar form at the end of chapter 25 of the manga with his Arrancar looks when he reappears in episode 110 of the anime, how come that they do not match or look alike?

Isshin in his Shinigami forms has tied around his left shoulder a white and sleeveless jacket. It looks similar to the ones that Shinigami Captains wear. That and coupled with the lessons he taught GF about how Captain Shinigami can control their zanpakuto's sizes, can it be that Isshin is a former Captain?

I know since the incident with the Shrieker Hollow in episode five, that if a Hollow was already rotten when human and has its mask split or slashed to death by Shinigami then goes to Hell.
Does that means that GF will be going to Hell also, even though it never happens onscreen?
