Celia had successfully befriended Gideon over the radio and was getting him to sloooooowly come around on the idea of opening up Lundegaard to outsiders. His #1 priority is the safety of his community, and she was convincing him allies were important. As a final nod to Celia he's not putting up real resistance if Roswell wants visitors to help his guilt.

SO he will at least attempt to talk to Crystal. Offer some uncomfortable condolences.
