Mr. Kimbley said he'd bet money on Fulbright being a Communist when we played chess yesterday. I agree with him - he tried to use that message as evidence to cast suspicion on Mr. Kimbley and didn't back off until Tohsaka confessed.

The timing is suspicious, too. If you're a Citizen trying to catch a Communist, it'd make more sense to make a case for why somebody should be considered a suspect early on and not when somebody just made a convincing argument that narrowed it down to two people, one of whom was later proven to be a Communist.
