Stiles is the pack emissary after a few years of training with Deaton. However, he doesn't do much other than run errands for Deaton and look after the pack. He lives with Scott in an apartment in Beacon Hills. During his travels around the world for specific items Deaton needs, he picks up a few things like gifts for everyone. Or a new tattoo. He has a few, but he clearly didn't learn after getting his first drunk tattoo.
