Quote #4
"Will you promise to always protect her?" [Eve] asked. She wasn't asking me. She was asking Denny, and I was merely Denny's surrogate. Still, I felt the obligation. I understood that, as a dog, I could never be as interactive with humanity as I truly desired. Yet, I realized at that moment, I could be something else. I could comfort Eve when Denny was away. I could protect Eve's baby. (6.20-1)
This moment between Eve and Enzo is about two things. First, Eve might be suggesting that she won't always be around to protect her daughter, so she's asking Enzo, and by proxy, Denny, to do it for her. Second, Enzo steps up to the plate here, realizing that while he can't take control of being human, he can take control of his own life, in whatever small way he can, and do what Eve asks of him.
Quote #5
"No one could force Eve to do anything Eve didn't want to do," Denny said. "I certainly couldn't." (29.104)
This interaction that Denny has with Maxwell and Trish after Eve's death shows that Eve has always been in charge of making her own decisions, especially those decisions related to her health. We see her time and again realizing that something's wrong with her but refusing to seek help. This decision was a way for her to take control of her life, even if that decision leads to her death.
Quote #6
"My daughter, with a mechanic—no, with a customer service technician. Where did we go wrong?"
"She's always made her own choices," Trish said.
"But at least her choices made sense. She majored in art history…She ends up with him?" (15.21-3)
Aside from showing how judgmental Tweedle Dee and Tweedle Jerk Face are, this also indicates how much they want to push their own perspective of what is "good" for their daughter onto her. Maybe they just need to butt out, eat some demon peppers, and leave Eve alone.
