So wouldn't it stand to reason that Ichigo's Id(or his hollow side, whatever you want to call it) has always been there, but subdued until brought to the surface during the pit? I'm just bringing this up because I see a lot of verbage saying he didn't have a Hollow inside of him until after the pit, which if I'm correct on the above, that's not true.
