With the books definitely. It’s such a weird line at that moment that it can’t be anything else. Someone guessed that it contained some kind of star maps that would help Mark find Viltrumite or maybe allies

With Marks help. Also he must be a pretty powerful Viltrumite, they seemed to have a great deal of respect for him. He referenced being one of the lucky few chosen to take over a planet telling me he’s quite strong even among his race

Right that’s always it. An unlikeable female character is only objected to because of sexist men on the Internet. As though it’s actually impossible for a female character to be objectionable selfish and wrong

From describing Debbie as a pet to explaining that their offspring is almost 99% Viltrumite I think the goal wasn’t to start a family, it was purely to produce Mark. I think it’s a long-term strategy. Nolan could have conquered Earth himself (maybe) but having a second loyal Viltrumite makes it that much easier. We see that in the alternate universe… He and Mark are just doing it themselves. Also why he told Mark when he was pummeling him that he can always have another kid, as in another soldier. Marks brother was probably a back up plan…
