I'm afraid Mrs. Hall may be in for some horrible news. In the episode when she met her son at the train station, her son's hat had H.M.S. Repulse on his hatband. The Repulse along with H.M.S. Prince of Wales were sunk by Japanese air attacks on 10 December 1941. 513 crewmembers of the Repulse perished. The good news is that over 1000 survived.
It will be interesting to see where the writers take this. The timing of the storyline would put this just before Christmas in season 5. Can we hope for a happy ending for Mrs. Hall and her son?
