It's a generally agreed convention that roleplaying characters can converse as much as they like during a combat. Not only does this allow for the fact that a combat lasting about 20 seconds in game time takes about half an hour to play out by rolling all the dice, it also allows the antagonists to engage in dramatic revelations or ridiculous taunting, as appropriate. Or both. So take advantage of it.

Jango Fett: Darth Maul planted me on the Trade Federation ship, disguised as a protocol droid.
Jango Fett: I was after evidence that they had the Lost Orb of Phanastacoria.
Jango Fett: {voiceover} "I actually met you and your blundering master:"
TC-14: {sepia-toned flashback} I'm TC-14, a protocol droid. Please wait here.
Jango Fett: {voiceover} "I was undercover, so couldn't reveal my identity."
Obi-Wan: {flashback} "Droid"?
Qui-Gon: {flashback} It means "butler".
Jango Fett: You fools were right there, where the Orb was.
Jango Fett: But you went off on some wild goose chase to the planet's surface, and then across half the Galaxy.
Jango Fett: {voiceover} "Meanwhile, I did the hard work of locating the Orb. They'd brazenly concealed it on their own bridge."
Nute Gunray: {flashback} What? What you say?
TC-14: {flashback} The ambassadors are Jedi knights, I believe.
Obi-Wan: Wow... long, rambling flashback sequence. You really are Maul's partner!
