Maternity, e1.7 he's taking blood from Liv's love interest. But he's not wearing gloves during the blood extraction nor when bandaging him up. And he did the blood draw one-handed. This seems VERY cavalier & dangerous when he clearly knows there is a blood-born pathogen that creates zombies (or at least some unknowns). Not only is this unprofessional and unscientific, but takes you immediately out of the feel of the (otherwise great) show.
