AKA The Sandwich Saved Me - S1-E5
Deliberate mistake: Kilgrave tells a man to throw a cup of coffee in his face, which he then does. Due to how hot the coffee was, it leaves the man in severe pain. The coffee cup was fairly small, had no lid and was exposed to the cool air, so even if the coffee had been boiled recently, it should have cooled down fairly quickly. (00:10:25)
Deliberate mistake: Inside the home that has been infested with Evil, the state police confront a possessed girl who attacks them. After some futile gunfire, the possessed girl is still standing. The female officer goes for her backup gun, which for some reason is a small over-and-under Derringer (meaning she has two shots maximum). She ends up firing the Derringer five times in just a few seconds, with explosive damage and without reloading. Director Sam Raimi probably staged the 5 gunshots on purpose, knowing that a two-round Derringer was a ridiculously-limited piece of firepower. Raimi probably did this as a tongue-in-cheek tribute to Ash's bottomless double-barrelled shotgun from Evil Dead 2 and Army of Darkness.
