At the end of Blood Diamond, why does the character Danny Archer hand start to bleed?

piss off uh

I'm not sure, it's a good film but there is one or two pretty strange bits in it, like what was that bit where he was in the woods freaking out all about?

The irony of my piss off comment is obviously lost on the people that gave me the thumbs down, irony needs wit to be appriciated i guess

watch the film again, piss of uh is what danny says

Been a while since I watched the movie, but I don't believe his hand is bleeding at all. I think he probably had put his hand to his side, where he was bleeding, and when he pulled it away he would obviously have blood on it.
