Plot

The BAU investigates seemingly random fatal explosions throughout Kentucky and Tennessee.

With Kristy on mandatory bed rest due to her pregnancy, Matt is in charge of minding the kids, their time which he wants to make different and special, and according to Rossi at his own risk. That home duty means that Matt is working from home as the rest of the team heads to Memphis, Tennessee to work on their next case, it where the latest - the third - mail bomb has exploded, each bomb in different cities in the eastern part of the country. While the first two bombs killed their recipients, the latest victims, mother and daughter Rhonda and Sophia Kirkman, survived but are in critical condition. The team discovers that the "mail" was not delivered by any official means and was probably hand delivered by the unsub. In piecing together the bombs, they discover each was encased inside a photo album, and without any spring loaded mechanism to detonate the bomb, the unsub was probably within sight not only to detonate the bombs via remote control but to watch each bomb explode, making the targets personal and not random, despite Garcia not being able to find any common bond between the victims. Rhonda's parents, Fred and Laura Kirkman, who made the trip to Memphis from their home in Michigan, may be able to provide that tie between the separate bombings. The question to discover the identity of the unsub becomes what his endgame is. The case hits home for Matt in light of his child care duties and the imminent birth of his and Kristy's fifth child.—Huggo
