I have Kira's affection maxed out, and have not gotten an option to talk to her since her and my character 'found something to occupy the time" and I have only gotten the one Companion Quest to Nar Shaddaa. Currently I am level 46 and at Voss.

What's all this about marriage? I have Kira at max affection and she has not wanted to talk to me in a long while. In fact, now that I think about it, I have only had conversations with her twice. Granted it was several of them bunched together, and the last bit of progress I made on the romance was when they went of to "kill some time."

True, but things had been manipulated my Darth Sidius for decades.

I wouldn't know, the game refused to let me progress the Story to Tatooine.

I love the comments your companions make during space battles. My current top two are from Kira during the mission where you have to take out the fighters while in an asteroid field, the name escapes me at the moment. The first one is, "This is your plan, really!" as I dive toward two rather large asteroids. The other I have only heard once, after some particularly bad flying Kira told me too "Let T7 drive."

I just had one a little bit ago on Alderaan with my Jedi Knight. I went to the base of the Death Mark weapon, which is overrun with Kiliks, or how ever you spell it. I find my Master and after mentioning the 'big kilik' that I had not seen, and busts in moments later, he comments. 'If it eats us, you're fired.' I had to smile at that one, even more so when I died and he practically soloed it.

Well in several cases the planets, such as Belamorra and Taris, are different levels. But there are some planets, such as Nar Shadda, that re the same levels. So I guess you can run around on those planets without a problem, but I don't think you would be able to team up and play each others missions. So my guess, would be no. But if you both had a character in the Empire and the Republic then you could play together.
