This has been bugging me for awhile re: Karen Wheeler.

In Season 3 when Karen goes to apologize to Billy about not showing up for their meet up at the hotel he has already turned into the possessed Billy and he turns around and hits her with a lot of force - presumably unconscious. Why didn’t he take her to the monster to become zombified? The scene cuts to black after she is hit and then it’s just not mentioned again. Doesn’t make sense.
