for those who asked about "nuQuinn"/"Sam's female blond anorexic friend"
Her name is Molly West and she's one year younger than Sam, what makes her sophomore when he transfers.
Her history: when she was in middle high and when he was freshman, she was perfect. Like, cheerleader, popular, good grades. Under big pressure, which eventually lead her into depression and eating disorders, a little like Sam in McKinley. Eventually it came into the point where her body and mind stopped handling it, she started to get sick and distance herself from everyone. She eventually lost her strength, she wasn't able to cheer anymore, her good grades were gone and so was her beauty. By the time 2nd year started, she had no more friends or position or anything and she became a weirdo and outsider, like Quinn during her pregnancy. lol so everything clear with nuQuinn thing. Guidance counselor started some kind of sessions with her, it wasn't helping much, but that's how she met Sam. They became friends and Sam didn't use her as a beard. She was like the 2nd person he came out to and definitely the closest friend in this school. They stayed in touch after he left, I guess she went to college to California and they were visiting each other from time to time.
Her looks: small and thin with triangle face shape, nicely shaped lips, like perfect heart-like notch on her top lip, blond, long hair she wears like Quinn in late S2 or Cobie in sixth season of HIMYM or Cameron in 4th season of House or something. IDK. Dark, brown eyes and dark eyebrows. Not so good complexion due to problems with eating, but it gets better with time, she also gains a little weight, but she never stops wearing long, big, baggy sweaters and tshirts and thick tights or loose jeans. Just her style, I guess. She can pull that off.
Her character: at first sight she seems like a total bitchy ice queen, but when you get to know her better she turns out nice, sweet and kinda bubbly. During her friendship with Sam she also becomes very touchy-feely (well, Sam hugs people a lot, doesn't he?). She gets very easily irritated though and it doesn't take much to make her start grumbling or self-pity. She's not exactly patient either, BUT, she knows Sam has a secret and trusts him and waits for him to be ready to revel it to her.
I talked about her also here and here.
