Lets Play a Game - World's Collide (Patreon)

If you, like me, don't feel like celebrating living in a dystopian nightmare OR you are lucky enough not to live here, I thought we'd play some games over the next three days. I'll even pick some winners.

Pretend the Mulvaneys are the Mulvaneys but Necessary Evils is Omegaverse. Which characters are the alphas, the betas and the omegas?? Which omega gets knocked up accidnetally and which gets knocked up on purpose? Bonus points (there's no points) for telling me your rationale.
