With John coming to a stop, Doc passes him this time, trudging through the snow in even paces. They'll wear themselves out wandering aimlessly in the snow, but it makes sense to at least walk to the end of the street and look around before they expand their search to include the trees and the rocks along the beach.

He comes to a slow stop when he realises he's starting to leave John behind, unaware of why he's stopped. He doesn't see Zed behind or anywhere near the building Constantine is staring at.

"Come along now son. Don't want to be losing you too." Why he's talking to John like he's addressing the twelve year old on the inside, he can't say for certain. Only that there seems to be quite a few impulsive folk around here.
