Dot reminisces about the war and Reg Cox being an air raid warden. Dot and Jim do some war songs. Finally, they get the all clear and are let out. Dot suddenly realises that it’s 15 years to the day Reg Cox was killed, and Pauline remarks that she’s probably right, and it was her Arthur that found him. Peggy tells Mark he's reminded her where her home is, and now decides that she doesn't want to move to Portugal after all. They tell Dan, and Frank adds nastily that they'll get Dan out. Dan says no chance, and Frank replies, "Then it's war." (thetvdb.com)
