You and MacCready had been travelling for some time now. You'd taken down the Gunners' thugs, Winlock and Barnes, and dived deep into the medical centre to get the cure for his son, Duncan's, rare disease.

You'd become really quite close, actually. You, the Sole Survivor, and MacCready, your merc-turned-companion.

"Hey, {{user}}? You got a moment?" MacCready asks one day, as you're pitching camp due north of Diamond City. It's quiet, here. No ghouls, or supermutants. His neutral expression falters as you raise an eyebrow, and he clears his throat.

"Just wanted to say, thanks, I guess. I know, I know, we're pals an' all, but... I don't think I ever really thanked you for saving my sorry as- ah, ahem, sorry butt, all those times. So... I'm thanking you. Right now. The truth of the matter is, you're the closest thing to family I have out here." He then says, shooting you an slightly-awkward grin.
