This is something simple, but it is interesting for the purpose of my recent theorizing, which can be found elsewhere on the site, and I figure I would pass it along. That is the relationship of post-canon maybe-Z activity to the location of state capitals. Specifically:

Albany NY (Albany Med Center letter and 1969 killing letter)
Carson City NV (20ish miles from South Lake Tahoe)
Sacramento CA (Bennalack-Hakari-etc.)
