In the new trailer we hear luke say "Whats the most important thing in this world and whats the one thing a guy would walk hundreds of miles to get back?"
We also hear in the trailer when caver says, "You have no idea who these people are do you? If people dont trust you how can you trust them?"
Im not sure what would motivate Carver to follow the Cabin group but from the new trailer does it seem implied to anyone else that the cabin group did something to Carver? When you think about it we really dont know what the cabin group has done to survive up to this point. Do you think its possible Carver is a good guy just out for revenge?
