Now that I think of it, there's actually a way we can know whom Tom chose... Only everybody should agree to it, otherwise it doesn't work.

At the moment Tom works alone, but it need not be so. We the village could decide by vote whom Tom tries to drive away. If the one who got the most votes (or, in case of a tie, reached the biggest number first/last) is still alive the next day, we know she isn't the BW.

Everyone should say what they think of it, and if even one person thinks it isn't a good idea, we don't do it (who knows, that person might be Tom himself).

Although hmm there are also a few problems. Firstly, the BW might have stunned Tom. Secondly, it doesn't tell us anything about the person's allegiance, only that she isn't the BW. Still, I think it's worth discussing.
