What did you tell Carver? in the cabin, he seems to the type of person who will turn your words against you. also if you jump and protect Alvin I am guessing that is going to come back and bite us.
In the cabin I try to tell there was a large number in this group and they would be back any sec, also I ask Carver why I couldn't trust them. I also told him I had a gun and try to lock the door - it didn't work.
