"Maybe the reason all your relationships fail is because you are already taken". The words of Christian's shrink, referring to Christian's love for his partner/best friend/idol Sean.
In an article Ryan Murphy stated the the show was inspired by his desire to display a loving heterosexual relationship between two men. I do not believe the psychiatrist's comments were meant to imply that Christian is gay. Rather that their male bond and love is so strong he is unable to commit to anyone else in that capacity.
So most of the episode focused on putting Christian in awkward sexually tense situations with Sean and watching him squirm. Ranging from, Sean demanding Christian to hold his testicles to Christian lovingly embracing his drunk/emotional/crying partner. Of course Christian got his obligatory emotionally vapid sex, first by joining in on some quality mother/daughter bonding and next with the aforementioned shrink. Who saw that one coming.
Next week, Christian confronts Kimber.
