Okay, as much as you hate Trish, you cannot blame her for that situation.Trisha is basically functioning on the level of a toddler, always has and always will so throwing tantrums and getting physical are completely the norm. I believe that Trisha thinks because she is a female (I know non binary now) but believes she can't physically abuse anyone because she presents as female.
Also she made Moses get rid of his cats that he loved because they were taking up too much time, they even gave a kitten to Shane and Shane's dog killed it... So basically Trish is the worst human.
