Ok, I know that whenever someones playing against Gryfindor, Slytherin goes for the other team. But I also thought (not to be rude to ANY ravenclaws, cuz I'm an ex-Ravenclaw) that maybe Ravenclaw is the only house that Slytherin likes. I think that because Ravenclaw is for the smartest witches and wizards, so they are a bit snobby, and Slytherin is really[i][u] snobby, so in a way they are alike. Also, you never hear of Pansy making fun of the Ravenclaws, once our twice, you'll hear from another student she's teasing Hufflepuff and Gryffindor, but never Ravenclaw. And then at the Triwizard Tournament, Slytherin and Ravenclaw got together and rooted against Harry. Some where voting for Krum, but the others had the badges saying "Support Cedric Diggory".
