Well, here's the thing: while I don't know for certain if S-K has 'a building' in Seattle, this doesn't mean they aren't active in Seattle. This may actually be a mark of Gold Snout's exceptional intelligence; so many major corporations have major presences in Seattle, he uses the city as an intelligence-gathering locale, while denying them a convenient place to sneak someone into HIS back pocket - he can have specialists against each corporation in less-tangled environs, instead of having to defend against everyone all at once in Seattle.
My advice: allow SK to NOT have a Seattle presence, thus making the sprawl a comparatively safe one for your dear one.
