Rein’s thrilled that there’s a new young kid for him to dote on, even better that he’s Hanzo and McCree’s! (visiting excuses galore) h’s heartbroken when Hanzo tells him how they came to have tiny Lucio, which ends up with the poor boy getting even more hugs, (Rein’s arm is at thick as Lucio’s torso easily) but Lucio has another member to his new snake family, and while Hanzo and McCree are always teaching him important life things Rein just takes him to goof off and play (he brings many snacks)
