It's been a bad month for Gary, between his own dreams, Mike's revelations, the messy relationship with Karen, and the disaster of a dinner with Cecilia. He's out walking in what's mostly a last-ditch effort to disconnect from everything, praying he doesn't meet anyone he knows--if he doesn't, he's decided to lock himself in the studio for a week.
He looks rumpled and exhausted and cold, and if you offered to buy him a coffee he would probably not say no.
