Mark is the hospital chaplain of the St. Jude's Hospital. He visits Mitchell at the hospital, after Mitchell has been attacked by Herrick. The hospital rang him at home. They do it everytime when a hospital employee is admitted. He came at 3 o'clock in the morning since the hospital workers told him that Mitchell is going to die. So he is going to say a prayer for Mitchell but is disturbed by the vampires Anthony and Gareth who come to the hospital to kill Mitchell. Mark and George scare them away by saying bible verses.
Mitchell comes to Mark, after he found out that Lucy has betrayed him and after he has done the Box Tunnel 20 Massacre. Mitchell is completely different, the vampire in him is really strong. Mark realises this. He says that Mitchell isn't that person anymore that George looked at when he was dieing. He says that he can save Mitchell. Mitchell however only wants to see Lucy. Mark refuses to hand out the contact details. He says to Mitchell that the man George wanted to save earlier, is still in there somewhere and that Mitchell needs to find him. When Mark accidently mentions Lucy's surname, Jaggat, Mitchell suddenly realises that she is the one that George and Annie are going to. He goes to the CenSSA to save them.
