Padmé: Come on 3PO, we need to go warn Anakin about Obi-Wan.
R2-D2: So... you're not actually going to help Obi-Wan bring him in?

R2-D2: Ah. I see! I totally did not get that before you explained that just now.
Padmé: This roleplaying is a bit subtle. You should talk to Annie about it.
Obi-Wan: I sneak on board Padmé's ship.
Padmé: I make a Spot check!
GM: What are you looking for, Padmé?
Padmé: Just... searching for hidden compartments. On the boarding ramp.
Obi-Wan: {aside} And I check my back for knives periodically.
