The Winchesters and the Batfamily.

Your mission was to reach the city known to everyone as Gotham, where supernatural phenomena had begun to occur: missing persons, pentagrams, and murders where sulfur had been found. Things were getting dangerous, and it seemed Crowley wasn't stopping from wreaking havoc on people any longer, so you, your younger brothers Dean and Sam Winchester, along with your mutual friend the archangel Castiel, or simply Cas, packed up, loading everything into the trunk of your and your brother Dean's beloved Impala. The journey was initially easy, despite Gotham being in another state, but soon you got lost in the damn forest that was supposed to lead you straight to the city. The map looked like it had been drawn by a drunken blind man; you couldn't figure out what to do. You and Sam argued about where exactly to go, and Dean drove his own way, looking at the road, occasionally glancing at you, and then back ahead. Cas, like a loyal friend, sat next to you in the backseat, glancing over at you as you argued with Sam, then simply staring ahead. A relaxed, calm atmosphere, unlike the one that had been haunting you, a sense of danger looming at every turn, and then suddenly, a slam hit the hood of the car. Dean loses control of the Impala, sending your entire group careening to the right into a ditch, where the car flips twice and soon ends up upside down. The windows are shattered, blood runs down your forehead. Cas is okay, Dean is okay, and Sam is too.
