____________ has the chance to get the most definitive proof of a traitor ever seen on the show

I won’t include Matthew because it seems he’s more interested in becoming a traitor than catching them, But Harriet has certified traitor catcher potential, and she could be about to get the best proof found in the show.

I don’t remember whether Matt was allowed to keep the paper that they’d written on or forced to keep it up, but either way he got a great look at one of Stephen or Rachel’s handwriting as a traitor. We know Harriet is very clever and was actively thinking of ways to trick the traitors. But by actually getting a strong example of their handwriting (whether it’s kept or not) is the strongest proof of whether someone is a traitor at the round table. Obviously this is dependent on whether she’d be able to match them but it could be very promising
