What should he do? He's unarmed, he has nowhere safe to run to and she's gaining on him. And then not only gaining but right behind him. Crying out in fear, an involuntary sound that he's going to hate himself for later, he pushes off from the porch and rolls away, narrowly avoiding getting skewered.

Having nothing better to do he picks up a handful of dirt and small pebbles and flings it at her as she recovers from the lunge with the rapier. Maybe later he might feel a little smug about dirtying her outfit, but right now he couldn't care less. He just wants to get away and get to safety.

At this point he's panicking not only from the fear surrounding him and the fact that Caedra is chasing him, but because he's scared that this is a precursor to something even worse. The last time he felt like this was with Jacob in the bunker - and that thought is bringing in a whole flood of emotions and memories that he didn't want to ever have to deal with. His head is pounding, his legs aren't obeying him the way they should - everything is wrong about this.

He careens around the building, running as fast as possible and looking back over his shoulder to see if she's gaining.

Unfortunately that means he's not looking at where he's going so he slams into the railing of a small deck at full speed, knocking part of it over and falling in a heap on the other side.
