In this episode of Criminal Minds, the following happens. We open with Emily going to a bar to meet a friend. We learn that another friend of Emily's named Matthew has died. Apparently from a heart attack. But they believe that he was murdered and so Emily agrees to look into it. She returns to the BAU and Hotch agrees that the team will look into it as a case, as there appears o be a pattern and a second victim. We quickly learn that Emily's friend had a drug problem and due to this he had nose bleeds (thorough using cocaine and other medications which are illegal). Soon a 3rd victim is reported and Morgan, Emily and Reid go to investigate the crime scene. Emily admits to Rossi that when she was 15 she got pregnant and Matthew helped her get to a clinic where she had an abortion. Matthew helped her throughout it and he started questioning the bible. He also started taking drugs and Emily blames herself for it.
They soon learn of the priest who is committing the exorcisms which is leading to the deaths of men and they learn that he has diplomatic amenity. Emily questions him but they have to let him go. Hotch sends Emily home for a few days, but Rossi takes her out on a little trip. They go to see Matthews's parents and his father admits that he was in the room with Matthew during the exorcism. His mother says that Matthew was never troubled until he met Emily. We learn from the parents that John (the fiend Emily met in the bar) was not told from them about Matthews's death. We then see that John is next in line for an exorcism. Emily and Morgan go there and find the priest performing the exorcism. As Morgan takes him out of the room, he splashes both of them in holy water. We also learn that John was the father of Emily's baby (at least I believe so after what I saw). At the very end of the episode we see Emily walking, and her nose starts to bleed. But why? Is she now sick? Is she doing drugs? Hopefully all will be explained in next week's episode.
