Galileo is the 2nd Impostor along with Purple. Though Galileo doesn't kill. Instead enjoying the trips. Feeling Good to be alive. Innocent. He doesn't worried about the fakes or the bodies in his wake. He is childish one. He loves taking pictures with his camera as well. He loves Purple. He doesn't care if Purple is killing. Galileo doesn't even notice the killings or bodies in his photos. He remains Joyful all the way through. Well maybe a little paranoid sometimes.
