Who Are You? - S1-E4
Plot hole: The whole "booby trapped frozen room" does not make any sense. Let's try to ignore the fact that it is entire speculation and a huge leap of faith on Mr. Fox's part that the trap works that way or that it's the only one, and that it wouldn't make sense (especially for a thief) to have something so erratic rigged to destroy your whole expensive equipment and jewelry stash - at most something directed at the door or a small charge to destroy your HD to cover your tracks. Still, it is supposed to react to any minuscule variation of temperature in the room and is triggered by a small sneeze, but Batwoman opens the door normally, and that alone would create a variation in temperature much bigger than her breath's (just think of what happens when someone does that in real life!).
