He could go back to his body and follow Jenna around, and she happens to go to the FBI building where Jamie and Laurel encounter each other again? 

I guess it also depends on when/how you want him to figure out how to communicate with her?

Trying to figure out what the FBI will do with Laurel right now. They're not going to fire her, obviously, and I'll have some people talk Laurel out of resigning. Maybe she's aken off active duty while the legal issues are happening and assigned to see a therapist, but then we can have Jamie convince her to bend the rules in order to get them in on the action.
