Grace manages to get Carl, and the home manager, to agree to his spending 10 days on the road with the young woman, now 23. Grace at 5ft 2inches, feels she has prepared herself for this time and Carl, at 6ft 6inches, appears to pose no threat to her, in her obsessed mind at least. But when they step out of the home to get into the car, Carl inadvertently displays full use of his supposedly disabled left arm. He also appears more lucid than he has ever been.
