If Nolan thinks of Marks mom as a pet, yet had sex with her and made a child with her, then what is the standard for pets on Viltram… Either theirs just a bunch of random species of people who are kept as pets, or they have normal pets(for them) and… um… do things… with. them…
He was comparing their relationship to one a human might have with a pet relative to their lifespans. He doesn’t view Debbie as a literal pet.
I thought when Nolan said Debbie was more like a pet to him, that he meant it in the most literal way possible
