I’ve always thought she’s looked like a “functional” coke head. That jaw is often swinging or she looks like she’s chewing the inside of her own mouth. She also acts quite fidgety and erratic at times.So, what exactly is Mary on?
Not only has her speech changed (she's lost the ability to enunciate or control her lower jaw) but she's also become mega-quick and aggressive no matter what she's saying.
Maybe it’s not coke, but she’s defo on something.
