Ah... the truce.

Talking is a free action, of course, but it is usually only applied during combat sequences. However, there are other situations where spending a significant amount of time discussing character actions can start to become strange, such as when there really is something important and urgent that you should be attending to.

Of course if it involves assisting an NPC, it's probably not all that important.

Palpatine: I'm glad you brought an armada. Quick, free me from these bonds.
Obi-Wan: Um... actually, it's just us two. And R2-D2. A stealth mission, if you will.
Palpatine: Then what's this huge battle taking place outside?
Anakin: Does it matter? We're leaving now.
Palpatine: Don't forget to untie me.
Obi-Wan: No, wait. There's fighting on board and a battle outside. This third faction must be after Dookû as well.
Anakin: Then let Dookû deal with it.
Palpatine: You know, you could release me instead of arguing. I am a retired Jedi; I can help fight our way out of here.
Obi-Wan: No, we can't just let Dookû deal with it. It could be important.
Count Dookû: {appearing on a balcony} Oh, believe moi... it is.
Palpatine: Never mind.
