I don’t need to hear any of your bullshyt rationales. I’m in it now, I’m compromised, but I will not have my children living in a house where dealing drugs and hurting people and killing people is shrugged off as ‘shyt happens!’
Skylar realized she fukked up, that she played a role in the situation, but that doesn't mean that she has to be cool with her children being in a position of danger.
Walt won't even acknowledge that there's danger out there. He doesn't think it exists. He's too far gone to realize that and won't until it's too late.
And like hex said, she didn't realize how deep Walt was in the game. She think he's a chemist when he's trying to run an empire.
