Yeah, Shepard had a pistol, somehow I think that if he slipped up for even a second the kid would get torn to shreds or have his face blown off. Also, the events of Arriaval would have made big news, I learned about 9/11 when I was eight, the kid would have been able to learn about this, especially considering that war could spring from it. Also, what do you nail into the mind of every little kid? Stranger Danger. As in, do go into cars with people like that! Also, he's a little kid and he's scared, are you really expecting him to bethinking rationally?
