Just have to add a thing to this, it actually hasn't got anything to do with the fact that they're missing their feet. But the two skeletons that are lying with their arms around eachother, their names are Esi and Sundaresh. You can read about them in the grimoire cards; Ghost fragment: Vex 1-3 [spoiler]Well, I'm 99% sure it's them[/spoiler] And Dr.Shim is in those grimoire cards too. My point with this is that everybody should read the grimoire cards! It's very intresting!
