- August 20th, 2012
I'm basing this on what I think are their inherent character traits, even if the Glee drama has them shifting all over the place.
Rachel-- Slytherin: incredibly ambitious and selfish, obviously. Even when she's trying to be nice (get Sam to stay in Glee 2.02, help Kurt win the election), she's cunning.
Finn-- Hufflepuff: good-hearted, honorable. He's really not brave enough and too much of a people pleaser to be in Gryffindor, but he always has good intentions and wants to do the right thing, even when he wimps out or fails spectacularly.
Kurt-- Gryffindor: brave, chivalrous. He's also manipulative and cunning, so Slytherin is an easy sell, but in the end he often sacrifices his own ambitions to protect his friends/family (blowing the high note in Defying Gravity, supporting Blaine as Tony). He's also the bravest character-- he stands up to large bullies, and he is completely honest about who he is regardless of what others expect from him. Kurt is all about taking the high road, no matter the costs to himself.
Santana-- Slytherin: cunning, manipulative. She's constantly scheming and messing with other people's drama to achieve her own goals, which is not to say that she can't be a good person also-- blackmailing Karofsky into dating her helped Kurt and New Directions.
Brittany-- Ravenclaw: inquisitive. I think she is goodhearted, and a hard read (no one is ever sure when she's joking or serious, understands or is clueless), so Hufflepuff could be a good fit, but no matter how off-base or how ridiculous the question seems to others she never stops asking. She is always attempting to understand the world, albeit in a magical way on a different plane from everyone else. It's just that people rarely answer her or take them seriously (again, hard to tell when she's joking) or understand what she's saying.
Mercedes-- Gryffindor: fierce. I'm not sure about this one, because I still feel like I don't *get* who Mercedes is, but I don't sense like she fits anywhere else, and Kurt needs one other person in his house.
Artie-- Ravenclaw: intelligence. I guess this goes with his whole nerd image.
Tina-- Hufflepuff: goodnatured, nice. People are rarely on bad terms with Tina since she is a team player and overall supportive. She could be in Ravenclaw, but I'm not sure there's much indication of that besides being on the Brainiacs. I think she gets good grades because she wants to do what she's supposed to do, not because she loves knowledge/learning.
Mike-- Ravenclaw? He has dance intelligence and creativity wth choreography and is on the Brainiacs, but I can't remember him being mean to someone for any purpose so maybe he's Hufflepuff? However, I guess I can't remember him being nice to anyone either, really.
Quinn-- Slytherin. Even after dealing with harsh consequences, she grasps on any way to get ahead and be on top. Even all the studying she does to get into Yale, I think is mostly so she can get out of Lima and not be a loser. She wants success above all, even if she has to fake being wheelchair bound to get pity votes for an inconsequential Prom Queen title.
Puck-- Hufflepuff. He's a toughie, but I think he's happiest with people who rely on him and expect things of him. His whole character development revolves around being the id-driven badboy, acting regardless of consequences-- as a Lima Loser of a deadbeat dad this is what other people expect of him. However, Lauren, his healthiest relationship, doesn't let him get away with any crap, he loves her for it and is happiest when trying to please her. He wants to be a good father for Beth, even if her mothers don't expect anything of him he knows Beth will eventually expect it of him. I think this is a case where (like Neville), he's sorted into a place he strives to fit, not where he's most obviously suited.
Sam-- Hufflepuff: good-natured, honorable. He maintains good relationships with his exes, no matter how badly it ends, and never holds grudges. He gives Kurt his word and in his book "that means something."
Blaine-- Hufflepuff: good-natured, honorable. His main goal is for everyone to like him. He's not brave enough for Gryffindor.
Lauren Zizes--Gryffindor: brave, nerve. She's ambitious, I suppose, but not manipulative. Well, she looked up the whole Lucy Caboosey thing, but she still doesn't seem like a cunning schemer, just a get-shit-done kinda gal. She's more likely to just tell you to your face that you suck and how you can improve, matter-of-factly and without malice, than plot ways to make you fail. She's always completely in being herself, which is brave.
Becky-- Slytherin: ambitious. She's a bitch and wants to be on top, regardless of how it affects others.
Jesse St. James-- Slytherin: ambitious, cunning, manipulative. Crazy boy version of Rachel.
Will-- Hufflepuff. Emma--Gryffindor. Sue--Slytherin. Beiste--Ravenclaw.
