Re: The "Matt Decker" Moment
The difference is that Decker was found almost immediately after the incident that killed his crew. Tracey was encountered after 6 months on his own.
I'm not a psychologist but after such a traumatic event, regardless whether it just happened a couple of days ago (Decker) or six months ago (Tracey), I'd say that you would still have the urge to talk about the loss of your crew and how you really feel about it with an equal starship commander. I.e. if you cared about your crew in the first place.
