Mafia 44. Time of Troubles

The princess blocked. Because
1) it was a date
2) she had a night watch earlier, and the blacksmith's block was absent.

It's foolish. After last night, it would be foolish to use a block and completely expose the peaceful players.

And how could he protect?

His night watch blocks and protects simultaneously; he goes after the princess, so it makes no sense for him to use a search. This means he used a block and clearly not on Plesen, since he died. And the main question arises: Where is the blacksmith's block?
