 Having failed to mention it earlier, Albert confirms that Robdal earned the nickname "The Frog" because he was a frogman in the Royal Navy.Consequently, he buried the gold at sea to hide it from the authorities and intended to recover it at an opportune moment, but was killed before he could do so.While Del vows to find the gold, Rodney once again asks Albert about his resemblance to Robdal; Albert just dismisses it as rumours, but does acknowledge that he and Robdal do look a bit alike.
