I wouldn’t be surprised if Betty has more offspring. When she cried about not being worshipped on Mother’s Day weekend, she made a point of saying “you’re my only son.” Not only child. I certainly could be wrong about the significance of that.
When Angela was wearing that bank-robbin’ mask, she said it was because she had an abscess on her mouth or something. Ugh, she seems so dirty to me that I imagine an infection somehow related to all of the medical shenanigans.
