[Doc nods] Yes -- he's lucky that, like me, he stumbled across some of the kinder residents of that Chicago when he arrived. I ran into it while Marty and I were trying to escape Arcadia and our Keepers.

[Marty grumbles] Yeah. . .kind of a kick in the teeth for both of us to get out, but only me to make it back home. I thought for ages Doc had died or gotten lost -- and couldn't figure out which was worse.

[Doc, immediately] Getting lost. Trust me.
