Meanwhile, Nollette sneaks into the cryogenic facility and tampers with Grable's storage unit, thawing his remains. Roland returns to the lab and is in the process of pushing the prototype engine to mach 15 when Nollette enters. Nollette admits to stealing Grable's work and prepares to shoot Roland, but is distracted by some equations. Roland strikes him with a computer keyboard and drags him into the wind tunnel. The agents arrive in time to convince Roland not to kill Nollette. At the same time, the rising temperatures in the storage unit kill Grable. Roland is removed from the care home, to be taken to a psychiatric institute for testing. However, as he leaves he stops to comb his hair in a style reminiscent of his brother, raising the question of whether he is actually free of Grable's control.
