Bad guys pretty much always have flunkies hanging around. Even if you don't mention any explicitly, it's often a safe bet that PCs can assume they are there.

As a player, you can usually just assume some silent bystanding goons, and execute plans that involve their presence. A good GM will just roll with it - unless they've explicitly stated that there aren't any henchmen or other subordinates in the vicinity. And yes, you can quote us on this to your GM.

Darth Vader: You seem... troubled, my Lord.
Palpatine: Fair is foul, and foul is fair; things without all remedy should be without regard.
Darth Vader: My Lord, if mine shadows have offended, say but the word and I shall mend it.
Palpatine: What's done is done; I shame to wear a heart so white.
Darth Vader: May I have your assent then, my Lord?
Palpatine: Receive what cheer you may.
Darth Vader: Thank you, my Lord. I shall bring the light of the stars to all the worlds of the Galaxy.
Palpatine: {troubled} The night is long that never finds the day.
{beat}
Darth Vader: {departing} This is the silliest stuff that ever I heard.
