IMO Notty claimed when she did for the reason that she knew she was going to be targeted / cced later in the game because of her tower role. By exposing it early, she hoped to gain the confidence of others under the false pretense of proving Inf's card theory wrong.
That is why she has spent so much time trying to convince us that the tower isn't bad, although everything I've looked up shows that it's like 85% bad.
Notty, you have said that lynching you prove Inf's theory is a very bad idea. How? Objectively, we can lynch someone who has a suspicious role and is likely (IMO) to be scum and if that doesn't work, then we have info. What does lynching Inf do?
