Everything in John wanted to run at the sound of his voice. It sent a shiver down his spine and made him cringe like nails on a chalkboard. That voice had been there at some of the worst times in his life...but they weren't all bad. That was what made it so confusing for him.
Despite his desires, he knew he couldn't just run away. Stephen had made a great point, that they didn't just have to worry about themselves. They had to worry about everyone else here who had powers, and John wasn't just going to leave them to suffer the tortures that he was fully aware Jedikiah was capable of.
