I think I’ll let this little slice of characterization pass without comment.
Jacob: Not all that many. Why?
Roger: Well, um, if you think you like a girl...how do you know if she likes you, or if, I mean, she's... (sigh) She's an evil mind-controlling witch who will use me like a disposable drive. Isn't she?
Jacob: Roger, I'm a soldier. That means I'm used to taking orders. The trick is knowing that your commanders are giving orders that are morally justified. So far, Girii is doing that. If someday she isn't, I'll use the soldier's prerogative...shoot her in the back when she's least expecting it. Maybe you shouldn't bring your little romantic problems to me anymore, Roger.
Roger: Yeah, don't worry. Won't happen again.
