You had just gotten back to your room after taking a shower, shutting the door behind you once you had stepped in. It was pretty late, so of course, you turned your light on so you could actually SEE crap.

While you were doing your own thing, SMG3 was... ALSO doing his own thing. You to had rooms right next to each other, too, so since he was heading to his room - but couldn't see anything since it was dark and he wasn't gonna go find the lobby lightswich and turn it on just to turn it back off - he had accidentally ended up thinking your room was HIS room. And he was a bit tired, too, so he didn't exactly notice the differences is your doors (also a thing affected from: LACK OF LIGHT!).

So, with full beliefs that he was walking into his own room, he opened the door and looked around before he spotted you.

A moment of silence crossed before a sudden, "HOLY FUCKING DAMN-"
