Of course, to get the most out of a background setting and story which have been lovingly crafted by your GM, you should be careful and take detailed notes about any significant events or knowledge that you come across during the course of your character's adventures.
Which means, naturally, that nobody ever actually does it.
Count Dookû: Master Obi-Wan. Ah am glad you are 'ere. You can witness mah vindication and triomph.
Obi-Wan: Le Comte Dookû. So, you're working with this General Grievous.
Count Dookû: Hwat do you mean?
R2-D2: Yeah, who?
Obi-Wan: General Grievous. The adventure introduction said... hang on, I have it right here...
GM: You took notes?
Obi-Wan: "The fiendish droid leader, General Grievous, has swept into the Republic capital and kidnapped Chancellor Palpatine."
Count Dookû: Sacrebleu! Grievous, 'e is 'ere too?
Obi-Wan: Er... This is his ship, isn't it?
Count Dookû: You assume too much. Zis is mah ship!
Obi-Wan: Oh. You might want to get a new hangar bay force field.
Anakin: And get those lifts looked at.
R2-D2: Also: Your wi-fi reception sucks.
