Ash has the power to communicate with ET's, a gift he needs to be stripped of by the end of the day or risk succumbing to its side-effects completely. This power is beginning to make him one of them - incredibly calculating, but devoid of any human emotion. He gains valuable time by ingesting prescribed sleeping inhalers which keep the symptoms at bay, but are quickly losing their effect as he grows more and more tired. In turn, he downs sachets of coffee to offset the inhalers, while trawling through the city meeting old acquaintances. It's through these human connections that he collects the pieces of the past that keep his emotional muscle working (a photo, a song, a piece of jewellery). By the end of the day his hope is to find a former interfacer like himself, rumoured to live in the city and that has rid herself of the gift permanently.
