The doorbell rings and Eric opens it and finds Christopher there, the guy who he found cheating with Jessie. But after talking to him for a couple of minutes he finds out that Christopher is actually a sex therapist that Jessie hired to find out how to get closer to Eric.
Eric learns that Jessie has a bunch of intimacy issues which stems from his past relationship with Spencer, which fucked him up in the head. He doesn’t want the same thing to happen between him and Eric, so that’s why he hired Christopher.
That’s when Eric decides he wants to help Jessie too.
