Given that it was behaviour you cited, I expected you to broadly describe the scenario, and then point out the town games where he was in the same situation and had a different reaction. If we are going to use meta, it must be established that it's scum meta and not just player meta. For context, in Game of Thrones Mafia, he was very preoccupied with questioning suspicion on him, so I feel like there is room for variation here. If you want to justify his lynch because you feel that he is not carrying his weight, I am okay with that. I am not okay with poorly-baked reads that hinge on a "meta" that, to my eye at least, isn't one that has been solidly established.
