The problem with me or Joseph fake claiming this is that we can be proven liars without the opportunity cost of scumhunting elsewhere. Normally with a claim that can't be proven in thread, town has to decide if they will wait for night actions to verify the claim to some degree, like a cop or whatever, or else they have to either just decide to ride or die and trust the claim through the end of the game, or they have to exile and flip the claimant to check their claims, at which point not only did they potentially exile a truthful claim, they also miss out on scumhunting and flipping someone else outside the claim.
In this scenario though, we can keep looking for scum outside of Joseph and I WITHOUT giving up the ability to demonstrably prove whether or not we told the truth. I could see this being a potential fakeclaim later in the day when choices have to be made, since in a lot of the scenarios, the exile goes through on the 3rd party if the drunkmayor is lying, but D1 where we can create 2 ICs (or 50/50 a scum), and still have time to individually test both of us on future wagons without sacrificing other scumhunting makes this a terrible fakeclaim. We should 100% do the (or some other plan if there is one better) test us both plan today, because if we both IC ourselves then we take tomorrow from an assumed 2/7 to 2/5 odds of randomly hitting scum, which is a better than 10% increase. If one of us lied, D2 we most likely have a 1/5 scum to look for while verifying with certainty which one of the 2 drunk mayors is scum.
I also wondered of this was some kind of gambit Dylan would try to pull off. But discounted it based on his suggested plan. (I don't think he would predict that faust would suggest not doing the tests, though if he had, that would work so well for scum!Dylan).
Unless of course faust is his partner and the whole interaction was scripted.
The simple fact is, whether or not faust and I had anything planned out here, the simple fact is we just wouldn't make it to the end of the game without verifying a mayor claim, even if town does decide to not do anything with it today. I'm flattered that it was even suggested that faust and I could/would have been capable of doing something like this, but if you really think about it, it's just not something that I can convince myself would work as scum (when thinking about potential for Joseph planning out a play like this for me).
