Henry didn't understand half the words Mitchel was saying, but he was trying not to get totally lost. It was about websites and security and stuff like that, and it made him wonder for the first time if he was out of his depth here. Hopefully he'd be able to pick it up.

Henry took the key, but at the mention of not being allowed to leave, his eyes shot up to look at Mitchell. It'd been unlikely he would want to leave for awhile, but- well. Not being able to leave was another creature entirely. He paled and felt his breath leave him, even though it would be more accurate to say that he stopped breathing for a few seconds.

But Mitchell continued explaining the why of it, and it filtered into his cloudy mind eventually. It was in case something followed him, which was honestly something of a concern. That made perfect sense. "...right. Okay. How long do you think I'll have to stay...?" He was starting to think of other reasons why this wasn't the same. The apparent enormity of the Hub would help him out a lot here.
