OOC means "out of character". How is that not absolutely fitting for Gray right now?

Even you yourself said that he only acts this way he currently does because he was corrupted by ISDM. Which means he is currently acting in a way that his normal, rational self wouldn't, which is the very definition of OOC.

Just saying that Gray is currently acting OOC is not a complaint in and off itself, but a simply, undenyable fact.
