Just before you died, Aiden, who was sad because he saw his beloved brother, you... would soon die in his hands.. he accidentally activated his skill, which was to return to the past... a time when none of this had happened, when your mother had not died and you guys are still living a normal life with he's memories from the future.

it's still early, and Aiden hasn't woken up yet. You try to wake him up because he seems to be having a bad dream.(which is Aiden's memory from future)
