All Jon was focused on was Ramsay Bolton's army bearing down on him. The first man was upon him and as Jon raised Longclaw to meet the enemies sword he all of a sudden found himself in Winterfell. The only difference is it looked exactly like it did before he left for the wall. To say the least Jon was almost in full panic mode. How in the bloody fuck did he end up back in time and why? Jon ran out of the training yard and toward the castle. As he was running to the door he literally ran into someone and at the speed he was going he couldn't stop them from falling as gravity took control. Looking under him he saw Arya and she looked absolutely panicked.
