19. Desperate Remedies

Complete story — includes the ending

A representative from the U.S. fails to negotiate a release of young girls who had been kidnapped by Boko Haram and returns with Marburg fever. Elizabeth arranges with the government of Cameroon to send in medical personnel to contain the outbreak, under the protection of Cameroonian forces. A man claiming to be sick blows himself up inside the medical station, killing 7. Doctors try an experimental drug on the American negotiator and cure him, but there are only three doses remaining. Elizabeth sends the now-healed negotiator to obtain the release of the schoolgirls and protection for medical teams by offering the head of Boko Haram one of the doses, as he is now deathly ill. Henry's team discover a tunnel between the compound where they believe Hijriyyah is and the gas station where an informant saw Disah. They attempt to kill Disah with a drone missile, but the plan is leaked and Disah escapes. U.S. troops use the tunnel to capture Hijriyyah.
