They also don't want them to have guns or stay for very long. Something is fishy and I said it while we were watching. Don't trust them at all.
I don't trust them at all, but it's not really because of the guns/staying things. I could understand his reasoning for the guns if they've survived without relying on them. Maybe he's not completely trusting of strangers out arming him. Also, I could see him not being thrilled about all them staying. Just more strain on limited supplies and more opportunity for **** to be ****ed up by random strangers. That being said, I still don't trust them.
