I meant with the names since Kindaichi referenced the family tree riddle (whose solution is related to their names), but I didn't realize that the watch itself was important too. :O
I meant that upon meeting Kindaichi in person, Yukimura probably thinks Kindaichi is probably as stupid as he looks, which is what a lot of people's first impressions of him kind of tend towards. XD
I'm surprised by the disappointed comments because I thought the author made very clear from the beginning that only those who fight dirty wins. Right up until the end, the characters all had a choice to walk away, but the ones who still vied for vengeance end up with a "Sword of Damocles"...
Honestly, Yukinobu-sensei could have just left this hanging and I would not even mind waiting years for him to revisit this series again since I enjoy the episodic nature of it, but this hard-nosed ending is so final!
