Season 2 Ep 1 Michael receives a letter from the pillar man to send. It's labeled " Mr. David Burton Sydney Australia "
Season 2 Ep 3 The TV in the background plays as follows: Broadcaster: "Resurrection, that's the claim in Australia. As witnesses described a man previously believed dead, emerging from a cave in Wanneroo, outside the city of Perth." Witness Interviewed: " walked out covered in mozzie bites, saying he'd just been in a hotel! " Reporter:" The man, identified as David Burt---" TV turns off
Later on in the episode, the publisher talking to Laurie references: "This nut in Australia says he went to the other side and can't die"
In Season 2 Ep 8 "International Assasin" While Kevin is on the otherside, talking to Paddy on the bridge, Burton shatters the car window, drags Kevin out of the car, and wraps a rope around his neck. He questions what Kevin is going to do to Paddy. When he tells her he's going to throw her into the well. To which Burton responds that he shouldn't and gives him a dilemma Burton: "Cross or Jump?" Kevin: "Why would I jump?" Burton: Because you don't want to hurt a child Kevin: She's not a child... Burton: yes she is, and if you do this it'll change you Kevin: None of this is real Burton: Friend... this is more real than it's ever been Kevin takes the rope off his neck and David Burton tell Kevin where the well is. Before he goes, Burton whispers some thing into Kevin's ear.
Up to this point, what he says is one of the biggest secrets of the entire show
