Who Are You? - S1-E4
Stupidity: Magpie in theory has the exploding pearls as diversion for her escape, but the pearls explode all too soon and in a room that she already emptied with the false alarm. Reality is that she has to face already zero security without the pearls being a factor, the moment she presses the alarm button. That's because for some reason every single Crow armed guard went to the exit to help the guests leave (in a most unprofessional way as they further crowd up the exit standing right in the way) and nobody remained behind to remotely keep an eye on the jewels. Also of course there is no alarm whatsoever on the jewelry cases, that can be opened at will. That is a serious joke of a security, and supposedly made by professionals, former navy seals, green berets etc.
