"Weird..."
WWYDI you saw a cure-all medicine called Fireflower Juice?
"Whaaaaaaa?"
WWYDI you tasted water that was like light?
Apologize profusely.
WWYDI Trumpkin called you one of the Kings/Queen of Old?
Probably feel miffed at the very least. Frustrated is the more likely emotion.
WWYDI Tirian told you to not scold like a kitchen girl?
(Ha! I know, right?)
Be terrified out of my wits, likely.
WWYDI you dreamed of a giant horse toy turning into a lion?
Tell them that my aim is terrible....
WWYDI you were really hungry, but fauns insisted on a solemn dance before the feast?
Let Caspian handle it.
WWYDI you were captured with Peter and Edmund?
Try to talk it out of it. If that doesn't work, then make myself look as big as possible and make lots of noise.
WWYDI the Pevensies suggested that you duel with Trumpkin?
