It was stupid for Wesley to be out on his own. He had known that, but he had come out just the same. Connor had all the knowledge that he did because of him, after all. If he hadn't tried to steal him away, then he never would have been stolen away to the alternate dimension with Holtz. He certainly wouldn't be nearly as much of a foe without all the training the hunter had instilled in him. It made Wesley feel an extra bit of responsibility in all of this. He hadn't been the one to shoot him or turn him, but he was such a foe because of a decision that he'd made.
He hadn't heard anything when Connor had snuck up on him. It had gotten dark and he'd been making his way back to the prison. The fact that Connor had basically stumbled upon him meant that he'd bee relatively close to his hide out, but that didn't exactly matter at the moment, now, did it?
Despite knowing the futility of it, Wesley wasn't about to go down without a fight. He lifted up his foot to stomp on Connor's, hoping to inflict enough sudden pain to make Connor let him go. He had just been given life back. He didn't want it to end like this, at the end of a vampire's fangs.
