(Yep, that's me! Thank you so much! Also, I'm already planning this out lol I'm totally writing it, I hope the OP doesn't mind that it kind of spiraled into Mental Health and How Much The Defenders Don't Have It. It'll definitely fit the prompt, though.) Omg I love all of this! And yeah, I see Matt's mood disorder as unipolar depression, but I can see it as bipolar too. And I agree with you that there could very well be some 'he's still young, he can be less fucked up than we are' going on there.

(Also, if you want to keep talking about this, you can also shoot me an email lol, especially since I want to know what you see of bipolar in Matt. Anyone can email me if they want! I feel bad for sorta hijacking this thread. I'M GONNA FILL IT, OP, DON'T WORRY.)
