Okay so i don’t want this to happen but I’m talking to my sister and freaking out for something that might not even happen. So what if in the finale of season 13 somehow jack accidentally kills sam and that’s how he goes dark side and then dean goes back to hating him and maybe even castiel too and they make Sam a pyre and jack says,” Thank you. I’m sorry. I hope you’re somewhere better. Goodbye.” like Sam said to him in episode one. I’M MAKING MYSELF EMOTIONAL OVER THINGS THAT HAVEN’T HAPPENED.
