'You're my brother', and a fairly recent one, when they're working on the route they plan to herd the walkers from the quarry along. Daryl is carting something back and forth in a wheelbarrow, and he stops to talk to Rick and convince him that continuing to recruit new people is in their best interest. He makes his point so quietly, no fuss, and then he says: "Your call", and what he really says is 'I trust you to make the right decision'. Love that moment so much.
