Patrick had witnessed what had happened with the random guy in the alley and he couldn't help but feel somewhat impressed and in awe of what Elizabeth had just done. If he was one to admit it, and he wasn't, he was a bit thrown off by her move, feeling a tiny bit nervous. Perhaps she wouldn't be as easy a mark as he'd originally thought.
Finding she'd stopped, Patrick knew this was his chance to catch her off guard. He looked around, a small smile coming to his face. They were alone, good. Finding a short, somewhat rusted pipe nearby, Patrick picked it up, knowing it would be perfect to use. Hey, he was looking to knock her out. As if he'd kill her here, in this disgusting alley. He'd much rather do it back in his apartment. Slowly making his way up to her, making sure to be quiet and invisible, as best he could, Patrick raised the pipe and moved to strike her on the back of the head.
