Two recurring characters are introduced in an episode that teaches the odd-couple plastic surgeons a few lessons about moral boundaries. Patti D'Arbanville plays Wallis Forsythe, a pornography mogul who meets Christian at a party and agrees to send some business his way. And Joey Slotnick plays Merrill Bobolit, a hack surgeon who's more successful than Sean and Christian because of his willingness to take on any client. Forsythe's easy money and Bobolit's sleazy competition inject a dose of conflict into Sean and Christian's partnership--as if it needed any more of it!
