The stars of Supernatural, which will be making its Season 11 premiere next Wednesday, decided to welcome the casts of Fox's Lucifer and The CW's Legends of Tomorrow (all 3 shows produced by WBTV) to the Vancouver studio they had occupied all to themselves for so many years.

Supernatural stars Jensen Ackles and Jared Padalecki put together a welcome banner -- with their charming mugs on it -- that reads: "Welcome FRESHMAN CLASS of LUCIFER and LEGENDS OF TOMORROW from your friends at SUPERNATURAL." And on Thursday, all three shows got together and took a photo underneather the banner.
