Penny's dead

Did Slater fight the men? Of course, he did. Even though he didn't know who had sent them, he fought fiercely. After all, in his quest to fulfill this mission for his sister's freedom, he had hurt a lot of people. 

People he had never known, and people he was sure were good. 

So it should have been no surprise that he was being hunted down. But even though Slater managed to hold them off for a while, he wasn't invincible. He was trained but still lacked experience. Against countless armed men, he eventually succumbed. 

They didn't open fire on him, though. All he remembered was being tased—repeatedly. The pain was unbearable, almost killing him in the most excruciating way imaginable. But he didn't die. 

If he had, he wouldn't have woken up to a bucket of ice water being dumped over his head.
