Patrick watches David the whole time, quietly handing back the other two leashes to the volunteer as he gets back to his feet, knowing that there's a decision that's already been made, and he's more than happy to go along with it. "Great," he says. "In that case, show us the paperwork we need to fill out and we'll take Henry."

He gives David an encouraging, warm smile, squeezing just above his elbow as he leans in to kiss him. "I can take him," he promises, sliding his fingers over the leash to gently tug it towards his own hand, feeling very proud of David for taking him for so long.
