This is an alley next to an abandoned warehouse and an old store.

There are electric lights shining from the mouth of the alley, piles of smelly trash half-blocking the way, rats, and a chain-link fence at the far end.

There is a fire in an old barrel, with two people warming themselves over it. There's the dull roar of traffic and city noise, audible but indistinct.

There is also a figure in a hoodie and gym shorts, holding a backpack close, sprinting down the alley towards him and fully willing to shove right past him if he doesn't get out of the way.
