As far as Cateagle's review, I had forgotten that line.
I like this Harry. He's frankly acting more along my preferences. "If they try to kill you, you try to kill them right back." One of the few things I liked about Firefly.
You might say its a bit much for a kid, but I owned weapons by his age. I knew the sounds bullets make going overhead, as well. Make you sit up and pay attention...or not sit up, actually.
