Sometimes it's a good idea to take a bit of time out to think about the events of the game. The plot elements and background information that the GM has carefully been parcelling out are clues to the grander scheme of things, and taking the time to consider them and figure out what's happening in the world around the PCs can be time well spent.

Assuming (a) you have the sort of GM who actually has some sort of background plot in mind, and (b) someone in the party isn't in the midst of being killed by enemies at the time.

Actually, the intersection of these two conditions is pretty rare. Maybe you should just forget about it.

R2-D2: All right, I reverse the lift.
[SFX]: CLUNK!
GM: Obi-Wan, take 2d6 falling damage.
Obi-Wan: Ow! Made of flesh, remember?
R2-D2: Sorry, I briefly forgot just how superior droids are.
GM: Speaking of superior droids...
{combat droids grab R2}
R2-D2: Hey! Mind the chrome!
Obi-Wan: You know, something's been bugging me. Why would those combat droids be using hull-piercing rounds? They could destroy their own ship.
Anakin: I'd risk destroying my own ship rather than let it fall into enemy hands.
Obi-Wan: And the lift droids said there was a battle on board.
GM: The combat droids hoist R2 into the air and shake him.
R2-D2: Not my gumdrop buttons!
Obi-Wan: Hang on! There must be another faction involved.
R2-D2: That knowledge fills me with comfort.
