I don't think Zakiyah is an awful person or anything, she actually seems pretty nice and caring. She was obviously a complete bore and non-entity in the game, but I feel like we didn't get to see much of her personality, she was irrelevant until her showmance.
Paulie was definitely wrong to bring Da'Vonne's child into the argument, but Da'Vonne also has no business speaking about Paulie's relationship with Zakiyah which again is a personal thing.
However, no matter what Paulie said she still should've sat the **** down and controlled herself instead of getting up in his face like she did.
