There are many reasons she didn’t go to the Barbie movie. For starters, her driver/caretaker Jade is long gone. Even if she could get Jade to drive her, the Barbie movie doesn’t strike me as man-voice Jade’s butch style. Once outside the cinema she’d also have to have the capacity to waddle to the correct theatre, stand in lines, and then waddle down to her allotted seating. Then there is the issue of her having to go out to a crowded cinema in the first place, where she can’t hide. She’d also need to pre-book gold seating to be able to fit in the seats, which I imagine would be in short supply in the early release days.
I very much doubt she could manage a cinema anymore unless she was in a bariatric wheelchair, and that means making a real spectacle of yourself if there are steps that staff need to use the special wheelchair stair machines to get you up and down. She definitely couldn’t do it on her own, and has no friends or family to help her. All she has is a pissed off ex-girlfriend who probably can’t wait for her replacement to arrive.
