"The Messengers attempt to find the Horseman of War before the Man finds him first. With the help of Joshua's visions and Peter's computer skills, Rose and Erin follow the leads to two suspects; a visiting Arab dignitary and a Senator who is the mother of an Iraqi War solider killed in action. Meanwhile, Raul continues his personal quest to locate his missing brother, unaware that the Man has set a trap for him. Vera continues to investigate the mysterious meteor rock particle which leads her and her co-worker Alan to a former lover who walked away from her nine years ago, and who was her son's biological father. The government is revealed to be holding the remains of the meteor that brought the Man to Earth as a top secret research project called Project Genesis. Peter is ambushed by the police and is arrested for murder."
Interesting. The meteor rocks seem to accelerate the life cycle of the plants they get near... wonder how much it screws up the people walking around carrying the rock? Could have shortened their lives by years. Raul finds his brother just in time to watch him die and Peter gets arrested by the police.
