Reichu: Shinji staring vacantly at his left arm… I think this shows that even though his memory may be "muddled," he apparently has the vague sense that something did happen to his (or EVA-01's, rather) arm.
thewayneiac: Yes, this is more of a wrist stare then a hand stare, but I think we should count it in our hand stare count. And like I said, each one seems to nearly always be in a different context than the one before it.
