Everything happened so fast, Leon could barely keep The impact caused by Rin jumping onto Leon's back was strong enough to cause the guy to stagger, dropping his knife in the process. He screamed, completely losing his normal quite sharp aptitude for logical thought, instead regressing to a more basic, instinctual thought pattern. ...Said thought pattern mostly consisting of 'Aahgetitioffgetitoffgetitoff!'. Which, considering the facts that he was unarmed and the wolf was hanging behind him, Leon himself wasn't all that successful in. Suddenly he felt a sharp pain shooting through his right arm, causing him to cry out in pain.
If it weren't for Rose coming to the rescue, things might've ended quite a bit more grim. Luckily for Leon, however, she did in fact do exactly that. Though he couldn't see exactly what she did by virtue of her target literally being behind him, he felt a heavy weight drop off his back. He didn't have time to think about it, however, seeing as 1: they were still in danger, and 2: Rose instantly started running again.
Adrenalin overriding pain and fatigue, Leon sprinted after Rose, not noticing the trickling trail of blood he left behind. Of course, just because you don't notice the fact that you're losing blood doesn't mean that it doesn't affect you at all, and by the time Rose led the two to a secret passage, Leon started to feel pretty bad. Still, they had to keep moving, so Leon did what Rose asked of him, albeit not in the most gracious fashion -- which is to say, he practically stumbled into the hole, the weight of the bag he was still carrying around dragging him to the ground. Forcing himself up once again, he kept running down the secret passage. It was not until he reached the end of the passage that he allowed himself some respite. He looked at his wounded arm, the sleeve of which was pretty much soaked in blood by now. several small tears ran across the fabric, presumably where that beast had grabbed him. To make things worse, the blood caused the fabric to stick to his arm, making it that much harder to pull it off and inspect the wound below. Hell, even slightly pulling at it hurted like hell.
((OOC note: Leon is still carrying around the bag. the 'heavy weight dropping' was Rin.)
