(May be OOC, I tried!)

Dewey stays at a table near the corner of the base, chair angled to face slightly outward. It gives him more space and makes it easier to watch the room. A boarded window behind him allows a small amount of light into the otherwise dark area, catching specks of dust that float in the air whenever Dewey moves a disassembled part or tool on the table. It'd probably make him cough if he was less focused on his task.

He has a short break for once, free from the group's latest mission. There's hardly anything better than getting to sit and fix up his pistol; he's rather delighted.
