well i was going to say the lack of co-operation but you need to remember only you know whats right and whats wrong and i know there is got to be incorrect infomation due to one person maybe the killer or could be that fact that they forgot and just going by memory. regradless, no matter how you put it, wont change a thing
edit: so maddie if we guess incorrect, does one of us die or is it a flip of a coin for everyone to see who dies?
