When Challenger discovers the wreckage of a World War I transport plane, he's captured by its pilot, Lieutenant Drummond. Drummond has been stranded for five years since the crash, protecting the plane's cargo—a crate of iridium ingots stolen from the Royal Navy. Challenger is astounded to see the iridium because it had been intended for his secret wartime research. The sight of it prompts him to remember the night five years earlier, when he was questioned about the theft by two British intelligence agents working for MI5.

His explanation falls on deaf ears, and Kim gives the ring, which she now considers tainted, back to him. To make amends, Greg surprises Kim with a brand-new replacement engagement ring. Or rather, a brand-new carbon copy of her original engagement ring -- which an insulted Kim also gives back, because it reminds her just as much of the other woman as the first one did. After a third failed attempt to pass the same ring off to her, Greg goes and gets her a different ring he personally designed himself. But her
