Unfortunately, he starts reliving the day when his ship was attacked by the Japanese and in a rush of panic, he jumps out of the vessel, falling to his death on a small submarine.

True enough, Diane and a couple of kids are grabbed and taken away while nobody is looking and when Dick realizes, he switches into Robin before he starts investigating the mystery. Suddently, he comes across a couple of armors that seem to move by themselves, but he soon learns that these are mechanical contraptions to scare intruders.  Following the clues, Robin finally finds some secret entrances in the castle that take him directly to the kidnapped people. When Robin confronts the man responsible, he learns that the man is in fact the last owner of the castle and that he has been forced to use scare tacticts to keep intruders away on order to hide the terrible secret behind the castle. The man takes Robin to a cellar where he introduces him to the very first ancestors and first lords of the castle, who had lived for 200 hundred years after discovering the inmmortality serum. Unfortunately, they have not stopped aging despite their inability to die and the man is forever haunted by his own ancestors.
