Okay now that this story is finished I have a more concrete opinion.
The writing is good and clear... there is only one thing that stands out that you could do differently next time.
You use a few descriptives like (examples): 'said happily', 'said softly', 'asked quickly', and 'said coldly'.
The problem with these is that in most cases they aren't necessary. They distract from the lines that are being spoke so I would recommend to try to make the dialogue speak for itself.
As for the plot, it turns out a bit like I thought. I for the most part like your way of making the fight at least a bit believable. Two things about it though....wouldn't the antagonist sense Grim's movements and actions much better if he was trained for twice as long in the Force? Also, I can't figure out what happened to Dal'vahn dying... what stopped the antagonist from killing Dal then going after Grim? Why did he go for Grim instead? Perhaps Grim got in the way or made threatening movements but I didn't see this clearly explained. Maybe I missed these plot points in my read-through, however.
Good story though, and I will be looking for your next one.

Well, see you don't know the other persons background, so you don't know how long he was trained in the force. All you know is that he is in his late teens to mid-20's and a former Padawan, that's all. So, while you have a point, this Padawan wasn't where a normal Jedi would be at his age. Which comes in later installments.
As for Dal's death, I thought I'd managed to make a clear scene, but apparently not.
As the man goes to stab Dal, he closes his eyes. When he opens them wondering why he wasn't dead he sees Grim standing between the man's saber blade and himself. The saber blade is through Grim's shoulder. Thus, the reason Dal doesn't die is because Grim stops the blade with his own body. And the reason Grim doesn't die is because it didn't hit any crucial area's and the man didn't continue his move, just turned off his saber.
The man's reasoning for going after Grim was 2 things, 1) his name, which he makes a big deal of, and 2) Grim stands in his way and tells him that he'll be the one fighting him from now on.
I hope I cleared it up a bit. I'll probably go through it and try and clean up some parts like I had done with the first couple chapters.
