Plot hole: The CSIs catch a murder suspect putting down a drink can when reviewing security footage of a robbery, and immediately realise they didn't see it at the scene so assume one of the first cops on the scene must have removed it. Thing is though, the murderers shot out the security camera before the actual shooting occurred, meaning there was loads of time off-camera for the killers to take the can with them, but the CSIs never even consider this - they jump to the conclusion a cop took it even though there's no actual evidence for that.
Plot hole: Bastion uses the special ability of Hydrogeddon, where he is able to summon another Hydrogeddon from his deck. He summons this monster by drawing the first card from the top of his deck, but there would have been no way for him to know if the card on top of his deck was a Hydrogeddon card. (00:12:35)
