Dia doesn't laugh often, this is true. Her life has had her end up on the more serious end of the scale, simply for the fact that she has to keep herself from drawing too much attention when out in public, or it's a job that she needs to take seriously. Mercenary work is Serious Business, particularly when you're hired as a guard or hired to take someone in (or down). To say nothing of the fact that Sith Business tends to be Serious Business as well, unless, well.

You're a little more unhinged than most. Dia had her issues, but she liked to think she had a more than tenuous grip on her sanity.

"I haven't been to the library, though I could probably stand to go. I imagine since it has a little bit of everything from literally bloody everywhere, I could find out some useful things on how to finish repairs on my ship." Or maybe how to fix that damned Holocron. Why was that one so important to her Master? She needed to know. Who's it was. And what information was stored on it.

"Exactly. We learn from our mistakes and our successes. Even if the mistakes can be bloody frustrating at times." She shrugged, "As long as I survive, I'm generally good enough to go on."

And given what she's survived, Dia's more than willing to take anything on. Although this would not necessarily be head on. She's still an Assassin, which is one way of saying that she fights smarter rather than harder.
