so matt as daredevil has got to have a lot of random bruises and aches. like, even after the body armor, that really can't help the unprotected parts of his face or blunt trauma, or knives that don't just go in that certain angle.

and karen starts getting suspicious bc matt's never that clumsy in the office? and he's used every excuse under the sun until they all sound pretty bullshit, but he's blind so karen doesn't even imagine he's out fighting crime every other night.

so she confronts a (thoroughly confused, almost offended at the insinuation) foggy.

your choice how that ends up just so long as karen fully believes it and is conflicted and matt is completely clueless that anyone pays that much attention to how much he's injured, because that's pretty average to him, after his dad, and after all of this.
