I hate it when characters make a point of being all, "X is definitely going to try to trick us, but we'll be ready," and then when the trap comes they show literally no signs of being wary or having any counters prepared.
Makes me want to shake authors like, "WHAT WAS THE PLAN!? EXPLAIN TO ME HOW THIS SCENE IS DIFFERENT FROM IF THEY EXPECTED NOTHING"
