Gabriel thinks about this for a moment. "It's my experience that souls will return to wherever they came from. The souls of humans originate in Heaven and return to either Heaven or Hell upon death. I've never heard of an alien soul going to my Heaven or Hell when it dies, so it must go somewhere else. I know aliens have souls because of what happened to Wes, but..." He shrugs. "I can't tell you anything else about it or begin to speculate about your galaxy."
