In the very first episode Nolan seemed to go back and forth about Mark getting powers. And when mark finally did, Nolan’s response at the dinner table was disappointment/unhappiness until Debbie kicked his leg.
Might be a dumb question and I might be overlooking somethin obvious, but could someone shed some light on that for me?
Probably not. Even though Viltrumites are generally assholes they usually love their kids and want the best for them. If Mark never got his powers, the hundred years of waiting for Mark to die would have just been a blip of a vacation for Nolan. There’d be no point in telling Mark that Viltrumites are evil conquerors because it would just hurt him, and it’s easy enough to wait him out.
