Meanwhile, Gavin receives cryptic texts from an unknown source threatening Olivia's safety, and Henry meets a media consultant interested in propelling his political career. A jealous Brian questions Louise about her rendezvous with Dr. Evans while she was recovering from her elevator accident, and one of Gavin's most crucial personal possessions is missing by the end of the evening.
