Now that the worst of 001’s mess is cleaned up, the team moves on to a more normal mission and Mac gets a new partner, FBI Agent Yates. Neither is thrilled with the situation. They are ordered to protect a TV pundit who spreads fake news and has latched onto the Travelers as a good source of inflammatory rumors to keep his fanbase riled up. Some fans take the rumors too seriously and pull off a tragic attack on a candidate for Congress and his wife.
The Travelers and their significant others continue to deal with the fall out from the kidnapping. David, Kat and Jeff have been through multiple traumatic experiences, some at the hands of people they trusted and care about. The memory inhibitor might work for a mind wipe, but, as we were already seeing with David and Kat in episode 1, the physical, muscular memories of fighting back during an assault are still carried by the body. And, as Carly tried to point out, for David and Kat, the erased 24 hours is just the tip of the iceberg, as far as evidence that something is wrong and that their partners have changed.
