Absolutely Salubri, sorry i just re read what i put and it's not too clear on the Captain point. I would definately say him being a former G13 Captain is the strongest possiblity however him being there just before Hitsugaya left if what i find ridiculous. Rukia for one would instantly recognise Isshin the first time she was in the house.
