Here's the problem I see in this argument. We must remember that some of the cutscenes we see show things our characters do not, and a lot of people also have metagaming mental bias as well after the hint that the Scions would be betrayed dropped in 2.5(2.4?) so of course some people are going to forget that our perspective is much more encompassing of than that of the WoL. Would my character be suspicious, hell yes, and I probably would have said something's up to the Scions via linkpearl, and been kind of paranoid around Nanamo (I mean, Wilred got gutted and our friend was MIA at the train tracks) but ultimately yea, I would have checked my weapon at the door, and been kind of screwed if I hadn't thought to dissuade alcohol consumption.
