That's so. He's quite intrigued by Preston's world, and I suspect he's trying to learn as much about it as he can.

I ought to inform you as well that I acquired three doses of Prozium for O'Brien. Only he can use it—it'll go inert if anyone else tries to take it. It's an experiment strictly for O'Brien, and hopefully it won't have much effect on Preston himself, but I thought you should know about it.
