If we pick the wrong one today both Menel and Eonwe are dead tomorrow and, as Rikae said, we have three people left who can be a thing. If Kitanna dreams of A, and I dream of the connection between A and B, we can pin it down for certain.
If A is guilty we have it.
If A is innocent and B is different from A, B is guilty.
If A is innocent and B is the same as A, C is guilty.
By the blessings of symbolic logics, we can no longer lose.
