Smile.
WWYDI you left your new torch in Narnia?
Mention it in MLIN and buy a new one, I guess. 🙂
WWYDI you were at a serious gathering and all of a sudden, you hear the Jackdaw say, "no fear!"
Laugh.
WWYDI Trumpkin asked you to go on an adventure?
Warily inquire about the nature of said adventure.
WWYDI the Pevensies asked to use your hat as a fish basket?
Hmm, depends on which hat... but if they were in dire need of it then I'd let them use it.
WWYDI you left a new present in Narnia?
Be really bummed, especially if I really liked it.
WWYDI someone made Narnia a sci-fi movie?
Probably see it, even though I'm not a fan of sci-fi.
WWYDI you were attacked by a dragon?
Hmm... I don't know. I'd either backtrack slowly or try to find out what is the matter. Depends on whether or not I think she'd rather be left alone.
WWYDI you turned around to suddenly meet a minotaur motioning to you to keep quiet?
Be freaked out.
WWYDI a minotaur answered your question of "Where am I?"?
Hold my breath and swim.
WWYDI you went fishing with the Pevensies and Trumpkin?
Be very dirty.
WWYDI you hear on the news that Narnians were in this world?
