Henry's eyes widened in worry when Jack set up the vortex, so it was good that it was explained immediately. He took a deep breath, figuring he had to go through it. If he'd be safe from that place there, then it was worth jumping through another hole.

Jack just gets stared at for a moment, after telling Henry it would be dangerous. "Yeah, I figured. I guess..." He gave the place one last look. "As long as I don't die here, it's fine." He wasn't sure if that was really how it worked, but he felt like he was marked already, like the apartment was holding onto him. He was already the Receiver of Wisdom, so it could still be finished, right? He had to keep that from happening, now that he had a chance.

So he stood and stepped in front of the vortex. "Do we just walk through it?" he asked.
