Pff. I quickly grew dissatisfied with my savefile and I restarted the game. Meantime, can somebody expert give me some spoiler-free tips? This is my first time through the game.
I found out that I didn't name my characters mistakenly: in the originally dubbed Italian version, Han was really Ian and Leia was called Leila. But this time I gave them the original names, for the joy of all you Star Wars otaku. :P
