We've all fallen victim to a bad retcon at some point in our lives. When the story we've been following takes a turn no one was prepared for and we have to act like it all makes perfect sense. It's Sherlock Holmes coming back from the dead. It's the reveal that an entire season of Dallas was only a dream. It's the author changing their mind and trying to convince you that it's all part of the plan. I don't buy it. And neither should you.
