Remi tracks down Aaron's immunisation records, which are inconclusive, then suggests she run a test for the antigens, which will indicate if he has been immunised.
Aaron is grateful to Remi for going above and beyond but remains embarrassed and remorseful over sleeping with David's stalker, Logan, which he begs her to keep a secret from his family.
