It’s been years and years since I read the books, but I remember one scene during which they’re performing surgeries on him. They’ve sedated him in preparation and he’s resisting the sedative in an endearing manner. I’m no super soldier, but I’ve had a lot of surgeries before and since and, well… The idea of resisting anesthetics seems unlikely to me if the anesthesiologist wants you under.

I also remember another character being impressed by the scout sent out to check out potential Spartans. He is impressed because she manages to make his ship’s AI lag by making a series of requests of it. Even at the time, though, I remember thinking that any system that couldn’t handle the requests she made (something like set a navigational beacon, bring up a few files, and play classical music) wasn’t all that impressive.

There are a few other random things I remember, like the introduction of Cortana and the end (at the time) of the series, but not much stuck with me, I guess. I never really liked the game series, so I guess it makes sense.
