The arms mentioned in Straker's letter to Brack are the mannequin arms, which are being sent to Panama for an avant-garde sculpture designed by Brack and sponsored by Straker. Brack himself is airlifted to hospital to recuperate from his injuries, and never gets the chance to admit to Ruby that he was the motorcyclist who paralysed her father. Nevertheless, although she will always regret her missed opportunity, her single adventure with the Doctor has given her hope for the future again.
