"We only visit one person on our list like this, the rest are 'side missions'.The subway trains were Grim being lazy.Gwyn will lead the thirteen survivors..We usually only visit possible..Candidates.As the world's population grows, there aren't enough reapers to handle all of the people, and some of the older reapers retire, so we're constantly needing new people..We look for unique people..Mostly of looks. Eyes are a common thing to look for. Gwyn and Grim were born with their odd eyes..They're both special though, they had reaper fathers or mothers, but their other parent still lived, or was given more time so they could have birth or raise the child..Their eyes came from that immortal parent.But, say..One of the new guys, he died recently, one of his eyes goes completely in the other direction of his other eye, and I think we have a couple with one eye being a different color than the other..You see where I'm going with this." Fate smiled, then took another bite of his chili. "You don't have to, no one HAS to accept unless they're the son or daughter of one of us, but it's one reason I chose you.."
