Before Sam reached the door he turned to face John. "There's a map. Here look," he told him. He took a few steps towards the other man and held out the palm pilot thingy. "I found it on the INFO tab. This place is huge, there's TONS of rooms. Nothings labled but I bet this is gonna make it a lot easier to try to find an exit."
Sam, head down and looking at the small plastic device in his hand as he tapped away at it, looking through the levels quickly. "If there is an exit," he added quietly. He had to show Dean. Looking back up to John, lips tight and a worried look in his eyes, he left the room heading back out to his big brother.
