...you're a tough guy when you've got a pack of zombies in front of you but let a few of them get knocked down and you run to your room? Scaredy-priest!!! 
Anyhoo... I'm assuming that if we followed the path of the retreating priest, that hallway is likely to end in a locked metal door or gate. What can we see of the north-leading hallway? Any torches or other features that might be discernable from where we stand? Does it appear to be the same width as the hallway we just entered from? And, assumptions aside, I suppose it would be wise to ask the same of the western corridor, as well.
