Mikey seemed less like he was resentful, and more like he was mourning a terrible personal loss. I actually rather like that Mikey tends not to be a resentful person, because then the displays of anger he does have appear all the more dead serious. It's relatively easy to push a character like Raph and make him snap at someone&mdash;short tempers are sort of his thing. But someone like Mikey doesn't do that without some serious personal baggage that's been hard earned through real longsuffering.

Wouldn't surprise me if many versions of Mikey quietly struggle with bouts of depression. Knock the wind out of his sails and he'll quickly try to get back up and keep going. If he appears really knocked down and has trouble getting back up again, you know he's seriously hurting on the inside.
