Dr Moore does make another appearance but I believe it's for one of several reasons..
- Cherry Peck (the tranny that Matt beat up) blackmails Matt into having Troy/Mcmara preforming his gender re-assignment surgery. Obviously they can't do the work that Dr. Moore can, hes the best at that.
- Quentin apparently becomes a victim - perhaps his genitals have been removed.. rumor has it that he supposedly has no penis as a shocker.
- Kimber is mutilated by the Carver.. he removes her brest implants and sends them to Christian -- perhaps he also mutilates her genitals
Next weeks 2 hour finale looks INCREDIBLE... I can't wait.. the Carver will be revealed in the last scene.
