The shadows are all of the ghosts that went to ghost hell imo (and probably balled up parts of ghosts torn in half when going into the light. I guess a lot of teenage boys are missing hands in the light?) And the thing that talked to Melinda at the light in the end of season 2 was most likely a shiny thing I want a plane crash to kill Delia. And Aiden, holy crap is he creepy looking. At least...
