Quote from Erin in Episode Three
Father Peter: What if this dog you saw, Erin, what if it didn't simply look like your dog... What if it actually was your dog? Erin: Right. Maybe. But as I think we mentioned, Toto's dead. My ma saw him get hit by an army Land Rover and buried him in our back garden, so probably not. Father Peter: [stands up] A beloved animal returning from the dead, now, we've seen this before. Orla: Ooh, ghost dog. Father Peter: No, not ghost dog. Resurrected dog! Don't you see? Toto was sent back to lead you to that chapel! To that statue! Because you're special, Erin. You have been chosen. Erin: Oh, Peter. It's all just so overwhelming. Sister Michael: Hmm.
