The Unit Episode 4.17 Flesh and Blood

The Unit is in South American rescuing a leader expected to lead a coup against the existing fascist governments. The man was trained by Jonas years ago and is badly injured. Unfortunately, their helicopter is damaged and, as Bob tries to repair it, Jonas works on helping his old friend. Time is running out, rebel soldiers are on their way. Jonas job is further complicated by the leader's impetuous son questioning his every decision. The guerillas approach as they're about to take off and the gas tank gets shot open. The leader makes a last stand to allow Jonas and his team to escape with his son, whom he appoints to take over. The son in turn, has grown up and asks Jonas to teach him as he did his father.

Also, Molly goes to a memorial service for the chlorine gas victims and runs in to Susan Gillum, the wife of one of the people the Unit was investigating as a terrorist. Susan reveals her husband disappeared the night before the attack and Molly lets Tom Ryan know. Tom tells Molly to meet with Susan and find out what she knows, but Molly refuses saying the woman is fragile and on the verge of drinking again. Tom says, if Molly doesn't, someone else will and does the job himself.
