Timeline wise I'm placing us somewhere after the Grand Fisher showed up but before Uryu was dumb by using the Hollow bait. Something that is going to REALLY piss Nero off. I'm thinking thats when my character will meet Ichigo and then Hana discovers his ture nature... when he obliterates the Menos with a cero that easily overpowers the Menos's. Then he encounters Byakauya when he's trying to caapture Rukia, gets his Gigai killed. Says his line and then decides to let them take Rukia back as he's more concerned with getting Ichigo taken care of.

In case you didn't read the post I mentioned it in his 'lne' is him standing over his Gigai that was just killed and saying 'You killed my Gigai.'
