Cure
A number of corpses found in DC morgues have paper slips in their throats with coded messages on them.
Provides examples of:
- Arc Words: "We are the cure!"
- Archnemesis Dad: The UnSub's true target is his father, who he despises for cheating on his mother and for moaning about how hard her terminal cancer has been on him.
- Call-Back: JJ comments that the email she gets from Barnes reminds her of the email she got back in Season 6 that was the beginning of her involuntary transfer to Pentagon.
- Shout-Out:
- Would Hit a Girl: The UnSub's only female victim is the woman his father left his mother for.
