SPOILERS FROM EPISODE 22
So... Am I overthinking it or is the "Who killed Robin?" case paralleling the Clash?
Robin is killed, the one who found her body is one of the suspects, and the murder weapon is his -> The one-eyed sleeping beauty is found by Rui who is one of the suspects and his touch of death is basically the murder weapon.
The oldest of the three mice brothers died -> Zenji died, he was the oldest brother (and it's suspected there was a third brother).
Humpty Dumpty fell from the wall -> No one fell to their death... Yet. Because remember that the very first scene of this game is one of the ghouls falling from a burning building.
That and MC being dressed as a witch while being cursed by the Kyklos... And the culprit who killed Robin is a witch who has been cursed by the Kyklos.
Am I just overthinking this?
