Hmmm... Honestly I'm unsure? Ray would probably be hurt but she wouldn't mind I don't think.
Although I was thinking about something happening (Much later on) where the other Spirits end up having their own bodies, probably something to do with Josh's power and Sara's Spirit. Dark magic.

Unless you wanted to add another character for Ray to eventually fall for? Although I'm tempted to have Ray fall for Sara, or at least have a massive crush on her old friend.
