Quote #7
EDNA: Well, I assumed you knew, darling. Why would he keep secrets from you?
HELEN: He wouldn't. Didn't. Doesn't.
EDNA: Men at Robert's age are often unstable. Prone to weakness.
Humorously (or not, depending on your perspective) Bob's lies make Helen think that he's cheating on her. And is it that a ridiculous thing to assume? All she knows is that her husband has been lying to her for months. Seems like it'd make sense.
Quote #8
HELEN: [crying] I am such an idiot. I let this happen, you know. The new sports car, the getting in shape, the blond hair, the lies.
In a way, Bob is having an affair, just not with a person. Instead, he's having an affair with himself—or, rather, a superhero version of himself. He basically swiped right on his own selfie.
Quote #9
BOB: I'm sorry. This is my fault. I've been a lousy father. Blind to what I have. So obsessed with being undervalued that I undervalued all of you.
After his family rescues him from certain death, Bob realizes just how wrong he's been. About everything. By focusing so much on his anger at his place in the world, he's neglected to think about the feelings of the people closest to him.
