Gregor is an elderly man who is also riding the train but doesn't seem to like traveling through the cursed forest as he is very supersitious of it.
After Josh had exited the restroom, Gregor told Josh about the message that Kate has left for him. The train was later derailed by Ernst, fortunately he along with most of the passengers were able to escape and took refuge in a nearby cave. The other survivors decided to venture into the forest, however Gregor chose to stay in the cave. He is eventually seen again when he saves Josh from being killed and they try to escape together. Gregor inspects a puddle of fresh blood, hoping to find some survivors nearby, however he was killed when he was sliced into two by a guillotine trap.
