I'm pretty sure the answer to all of these questions is Gryffindor, but I can't remember for sure. Which houses were the following people in when they attended Hogwarts: James, Lily, Remus, Sirius, and Hagrid? Were they all Gryffindors? And what about Wormtail? Can't imagine him being a Gryff, but why else would he hang with them?
