@RaijinslayerWell, if he knew about the experiments during the war that would probably not fly in Tiger's book or at least I would think not.
Hmmm not really sure, maybe as a commander pushing Tiger too hard? I mean we all know that Blood can't really do compassion well so if Tiger was at a breaking point and was looking for comforting words that could go wrong. Not because Blood meant too but just kind of saying the wrong thing?
I highly doubt that Aquamarine being hurt or in everyone during the wars eyes killed by Bloodstone would have been the reason but maybe.
Can't really think of any other theories at the moment
