In Season One, the story went something like this: Dick Whitman enlisted in the US Army and was drafted over to Korea. Once there, he and his commanding officer, Lieutenant Don Draper, were under attack when attempting to build a field hospital. As the only survivors from the group, and surrounded on all sides, petrol covered the ground when Dick accidentally dropped his lighter, killing the real Don Draper. Or at least that's what we thought before last week's penultimate episode. It was sort of dropped in on the sly, but the audience is now left wondering if what unfolded really was an accident. At a charity event for POW veterans in Oklahoma, Don is pressed on his experiences of the Korean War. Naturally he's a little reluctant to share until the others get in on the act. When he learns one man killed and ate a group of German soldiers, despite them surrendering, his tongue is loosened up a bit. This time though, the story looks a little different. Rather than an accident, he suggests he killed him on purpose, blowing him to smithereens. It's almost impossible to know what was really going through his mind when it happened, but if he did kill Don Draper, he's not only a murderer - he was lying to his widow Anna along.
