Corn's black is very early if he is false.
If he is false, he looks like Madman.

Yamibuchi>>16 is reasonable.
If Montague is false, he would wait Corn before say his result.

But there is another thinking. How about following:

Montague gave up to guard Nemo from Corn and cut line surely.
If Montague and Nemo has red windows, they can still win.
If Montague is wolf, Psychic roller and lynching Nemo & Corn is one of ways to win.
