The Postman (No. 173)

Wu is gone and the FBI needs to be able to show their workmanship in solving cases so the task force can continue. Red has expunged himself from all records so even though they are so effective, there is no record and nothing to hand a subcommittee. Red throws them a bone, a man who was convicted of a murder he didn't commit and sought revenge when he was out. He is an engineer and develops a weapon to deliver a deadly chemical agent. The fun part of this episode is that it is not based on previous activities by the group. Of course, Reddington is on call and is needed to close things out. Satisfying ending with a little positive payback.
