Luke: Couldn't you have fired something less dangerous? Like a small nuclear device coated with touch powder?
R2-D2: What, and risk failing due to insufficient firepower?
[SFX]: whooooooooooossshhhh... {the laser sword flies through the air towards the skiff...}
Leia: You had a laser sword and you fired it over the Sarlacc to the skiff? Why didn't you give it to me? I could have held it to Jabba's throat and gotten us all out of here!
R2-D2: It's incredibly dangerous. I didn't want you killing yourself.
Leia: Oh? Because I'm a woman?
R2-D2: No, you're a PC! Unlike Lando.
Lando: I don't know how to use a laser sword! Even trying to catch it is a terrible idea!
R2-D2: Sheesh, NPC allies with self-preservation traits are the worst.
