| One thing to consider is that there's dead, and truly dead in this game. If a character is simply dead, it means they're unconcious, not effective, but still can be healed; left without treatment they may either recover on their own or die completely. That's how the D&D-based system KotOR 2 is made from works. When your allies fall in battle in this game, they're not truly dead. Just knocked out of the fight. You sometimes see this in Neverwinter Nights, too; If a character is simply dead, they have between 0 and -10 hitpoints; barely clinging to life, but still can be healed. If they're truly dead, they have -10 or less hitpoints. Now, this is kind of rare, except at very low levels since it takes a hit hard enough to knock you negative but not enough to put you past -10. Mira likely believed Hanharr was truly dead, or she simply refused to finish him off based on principle.
As for the last bit, Mira was going to find you at the academy. Of course, because the game was never finished we never get to see this. When I played, I had Mira kill Hanharr on Malachor V. I figured it was doing him a favor, and that there's some people who leave you no choice. After all, he would have died when the planet broke up anyway.
On a similar note, HK-47 actually saved the remote from Goto, in a rather comical dialog, but we never got to see this either. End result is the end of the game is rather linear with little plot.  |
