He isn't the first person we've had arrive here who was dangerous where they're from. I appreciate the warning. We're lucky to be able to make a plan first, instead of going in blind.
If he's as dangerous as you say, we can't let him wander around. The best thing for all of us is that he believes we're not here to experiment on him or capture him. I'd rather have him here than out there, where we can't keep an eye on him. I can be nearby, if necessary.
