Brent and Player survive to see new arrival Larry Page, a supposed RAF pilot officer -- though his story does not seem to check out -- and Walker, an actual RAF man, picks a fight with him. However Page actually turns out to be a spy, a member of Special Operations but, with no military status, he risks being shot as a spy. Consequently, rather than escape to resume operations, he opts to stay in the camp posing as a P.O.W.
