While Neal continues to work on the codex and romance Rebecca, Peter's ongoing grief about the death of an agent under his command comes to a head when his ex-girlfriend, Jill, comes to town. Both were at Quantico years ago, but split up for reasons unclear to Peter. But Jill needs his help to finish buying a codebreaking MacGuffin before private military contractors or a rouge state can get their hands on it. It all seems innocent enough, but Peter's wife Elizabeth doubts Jill's good intentions. Will any of this connect back to a carjacker using a stolen FBI badge?
