On the flight back home after the events of S10E4 "The Itch," JJ finds herself haunted by Jane's words. With each case, a piece of JJ is left behind. She fears that one day, there will be nothing left of her. Episode tag, with allusions to "200." JJ-centric, with eventual team/friendship fluff.

The last thing Rossi had bought on for, when he'd returned from retirement, was the mentoring of an FBI oddball, a freak of nature, a socially inept, brilliantly gifted, geek. Nerd. Dork. "Nope, not for me. He's somebody else's problem." Until the book project. Set in Season Five.

JJ has discovered that sometimes even the best excuse cannot cover up the truth. And when the person who learns the truth of her circumstances is none other than Erin Strauss, will their friendship pave the way for a relationship with the man of her dreams? JJ/Erin friendship.
