The fact that 75% of the ship didn't reveal what they found out was suspicious? Really? Maybe their information wasn't useful, or better yet, they didn't put much thought into it because they knew it wasn't reliable. The thing is, you're thinking that both you and Cera receiving that 'similar' information is meaningful when, in fact, it is not as meaningful as you think. Saff said that half was the truth and half was a lie. She never said what that lie would be. Getting heads (or tails) twice in a row on a coin flip happens frequent enough to make the possibility a concern, so saying that information is reliable is not completely accurate.
BTW, I searched King's room, and what I got back was that he was the Night Watchman. We know that isn't true now, and given that he's voting for me now (a vacationer) means either he's a pirate or he's being manipulated from the outside. I didn't come forward with this because why expose a role like that to everyone. I would certainly be putting him in danger if I did. It makes no sense for everyone to reveal what they got because A.) it's going to be questionable, and B.) if it is true, it could possibly endanger that person, depending on the role they are.
