Oh, I could see how you mistook what you saw the other day for cannibalism, but that was Zod attempting to seduce Tes with all his super alien charm. He thinks so little of her, of humans, of women, that that is all the game he assumes he needs.
He's lying, and she's revolted.
but they both got enough at stake to pretend they don't want to vomit for a little while.
Murdering his stooge the week before that was so foreplay.
If Zod wasn't being written as a romantically thumb tied clumsy ass, it could be going somewhere.
We've met his wife.
She obviously wore the pants.
