In season 1 when Samson didn’t end up in a coma I wondered how they were going to handle the Omnipotus attack, since that attack while Mark was a on Thraxus is what starts the chain of events that eventually leads to Mark and Cecil’s falling out and mutual distrust of each other (but honestly I don’t think Mark could have helped with Omnipotus that much), which is kind of a huge part of the story.

Now I get what the show is doing though:

(Prediction for the next episode/important comic spoilers. read at your own peril)

!It’s now clear they’re going to do the First Sequid Invasion/Lizard League Nuclear Takeover while Mark is away. Mark isn’t super vital for the Sequid storyline at this point (at the very least Immortal or Bulletproof are more than capable stand ins for him). But when Mark comes back Cecil can hit him with the “your job is to protect this planet. If you had been here I wouldn’t have had to devote as many heavy hitters to the Martians and had some more boots on the ground to handle the Lizard League. But because you disobeyed my orders, Rex is in the hospital, and Kate and Rae are dead.”!<

I shouldn’t have doubted. The writers clearly have a handle on things.
