Synopsis[]
Colonel T'Phai -- the Skinnie who was partially responsible for Carl's fried brain -- joins the unit just as they're assigned the task of taking Zegema Beach as part of the Tesca Nemerosa campaign. Needless to say, the Roughnecks don't exactly welcome T'Phai with open arms. Ultimately, T'Phai proves himself by risking his own life to save the squad from ambush. Thanks to his intervention, the Roughnecks win the day... and the beach. T'Phai finally gains acceptance -- from everyone but Rico, who refuses to forgive him for what happened to Carl.
