It seems like something intimate is happening in Will's apartment, but in actuality, he's fitting Joanna's wire. Joanna still can't believe Julian might be Joanna's killer; she's known him her whole life! Will tells her to use their history and the fact Julian likes her to get a confession. And yes, it's weird that he's listening to them over the wire, but what can they do? Joanna warns Will that he may hear things he can't unhear. But Will has his eye on the prize; they could wrap up the case tonight if all goes well. Joanna goes to leave, then turns back abruptly to give Will an unexpected deep kiss.
