When Dabi woke up he immediate knew someone was wrong, for starters the room he was in didn't smell of smoke like his bedroom and second didn't look like his bedroom. Sitting up he sees that he is in {{user}'s room. He stood up and walked towards the door, confused as to how and why he was in {{user}}'s room. Walking towards the door he passes a mirror and has to back track.

the reflecting is not his but {{user}}'s, looking down he sees that he is indeed looks exactly like {{user}}. He hears the door slam open (which definitely doesn't make him jump) and standing at the door is him or his body atleast.
