Just some not-so-normal people in a laundromat
It was a common thing for Martin to do, teleport to a city that sounded mildly interesting and go exploring. Manny had been going with him for walks around Boston to get more used to being around people and crowds, and he tried from time to time to walk the less crowded streets himself sometimes, which was what he was up to now. Seattle had had a demon infestation apparently some time back, which meant it was a prime location for some exploring, maybe he'd even find some demons to hunt!

After walking around, hands in his pockets, on the mostly emptier streets during the day, Martin saw some crowds up ahead and frowned, slightly worried. He had no idea what the crowd, a rather small one honestly, was there for, it could've been a protest or a group going to a game of some sort, but it still made him uncomfortable. Rather than attracting attention by teleporting away in the middle of the street, Martin noticed someone exit a nearby door and he hurried in before the door could shut. 

Hands still in his pockets, he surveyed the place. It was annoyingly loud, the sounds of a bunch of washing machines going at once tended to be, but it was rather empty which was good. So Martin hopped onto one of the laundromats many machines and decided to wait for the crowd outside not too far away to pass by or disperse.
