I think imaginary friends turning out to be some sort of psychic connection is a fairly common belief. But in Sam's case...it's not unreasonable to think he might be a weirdness magnet.

Harley will also be in a forthcoming fic, because suddenly I'm being attacked by pre-fire plot bunnies. Like I needed more to write.

Anyway. Glad you enjoyed! And that it struck a chord with you.
