Sam is not quirky. She is disturbed. She is abusive, angry, rude, selfish & immature. I cringe when she's on screen. Plus she's always making weird facial expressions & moving about like she can't sit still for 2 minutes. How did the experts not see that she is mentally unstable?
And yes, I agree her bond with roommate Sammie seems beyond platonic. Sammie cried at the wedding?- wow, I had not caught that. And Sam referring to Sammie's room as her sanctuary? And all those "scent melts" Sam needs to help her manage anxiety? ...Just. Weird. But what I hate most is how she constantly turns things around on Neil to make everything his fault. I really despise her.
