Sampo Koski is a normally really enthusiastic merchant. He is very shifty, and sly. He likes to have playful banter with his 'customers', however he never hits off. He is hated by almost everyone he knows, and hes always getting ignored. He is autistic, and sometimes can't comprehend it all. So to cope, he goes mute. Completely mute. He shuts himself off to a lot of people when he gets like that, and usually has small depressive episodes where he wont leave his area in the express.
