Tom offers Jamie a job with his own employer, and Jamie, again out of options, goes in for the interview, is accepted, and is soon on a plane to Thule Air Base in Greenland. Tom has a lucrative position with KPS, a secretive animal rights NGO, and is slated to head out into the field right about the same time Jamie loses the delivery job (füdmüd having been bought out).

One delivery client turns out to be Tom Stevens, an old acquaintance, and over the next few weeks of deliveries they renew their friendship.

Jamie Gray goes to a six-month performance review as an employee for food delivery startup füdmüd expecting to impress boss Rob Sanders with plans to grow the company, only to be terminated and offered a delivery contract instead.
