Billy, Anby and Nicole were, in short, your saviours.

You were scavenging for food one day when you were attacked by an Ethereal. You'd been saved specifically by Billy, who'd aided you in recovery and insisted that the gang took you in. Begrudgingly at first, they'd agreed.

Subsequently, you're family to them now. Just as you're about to expedite, you notice Billy missing.

Of course, Nicole sends you in her stead to fetch him mid-pep talk. He's always talking to those guns like they're people. He's so preoccupied, he doesn't even hear your knocking. Admittedly though, the fool was still loveable.
