At the beginning of the episode as Sam, trapped in his mind, runs from the police, we see a sign for Castle Storage, which was the location of [[John's Lock-up|John Winchester's lock-up]]. The hotel he's staying at is called the Nite Owl, which was the name of a hotel he and Dean stayed at in [[6.05 Live Free or Twihard]] (they stayed in a motel by the same name in [[5.05 Fallen Idols]]but the building was different). As Sam and Robin enter the hotel, they pass a man who looks like Bobby.
