Rashid's pills
I guess no one can really know unless they say it, but I was wondering if I might have missed it mentioned... what kind of pills was it that Rashid was giving Brandi? because that might have had a lot to do with the way she was acting. It could have been something that made her paranoid, out of touch with reality or lose a bit of her morals. It honestly did seem like she was a totally different person in the begiinning of the movie... she had a good job that took a lot of patience, kindness and selflessness and she did it so well that the residents favored her and she was in the running for a promotion. By the time the accident took place she seemed like she couldn't really make any moral decisions or understand what was actually happening. If anyone heard it mentioned or might have an educated guess depending on what the pill looked like or it's symptoms, I'd be really curious to know.
Buzz! Your girlfriend! Woof!
