Imagine you’re a normal fucking human, suddenly a superhero shows up, you marry them. He ends up being a fucking world conquering tyrant, and then you go on a little bit later and still fucking nail your job as a real estate agent? That woman has more grit than any human should.
I don’t think she has to lash out at Mark in order for it to be realistic at all. She loves her son and he literally almost got beaten to death, there are plenty of real people whose low points after something like that wouldn’t involve taking it on their son who just went through arguably worse. It’s obviously fine to prefer to comic version over the show version, or vice versa, but to act like it’s a difference in levels of realism seems silly to me.
