Jim nods, also uneasy about it. Sleeping is one thing. Being forced unconscious is another. And while he feels that this might be one of the safer places to allow himself to be so fully knocked out for the night, it still goes against his survival instincts. If something were to happen, and he's unable to wake up... At least Hunter is here to keep him out of danger.

"I think we probably shouldn't share a bed," Jim suggests, reluctant to say it. While another person might be a comfort, if the potion doesn't work quite as expected, he would be horrified if he woke to find he'd strangled Hunter in his sleep or something.
