You decide you can wait for a little bit longer. You cast your eyes about, searching for something to do, and they come to rest upon something peculiar. The window sill is covered in salt. Upon further inspection, every opening to the house is blocked by a salt line! You aren't entirely sure why, but it's scared you into staying for a little longer.
A few minutes later, the brother's came back and find you more then a little spooked. "Everything's okay now. You can go." Sam smiles kindly at you.
"Oh my god, is that BLOOD?" You exclaim. Both the brothers are covered in flecks of blood. You are so scared that you make a run for it.
Several weeks later you've mostly forgotten about the strange brothers. You had gone back to the car, spent the remainder of the night there, then in the morning you had sorted through your family's stuff. Now you are back at college without the slightest idea that anything is strange or supernatural with the world.
THE END! Well done! You not only survived the ordeal but you managed to remain blissfully ignorant the entire time! This is the only ending that allows that to happen! Congratulations!
