Use it to scare the living daylights out of Peter and/or Edmund (Yeah, I know it's mean, but it'd be funny! 😀 )
WWYDI you found yourself fighting a battle with a Mary-Sue?
Thunk her over the head with a dictionary (or a BIG book of literary criticism. 😛 ) 😀 .
WWYDI you found yourself trapped in a Calormene dungeon with a Sue?
Take the dictionary (or BIG book of literary criticism) from Jaygee and whack the Sue with it 😀
WWYDI you were surrounded with hungry wolves and all you had was a piece of cake from King Edmund's party yesterday (which was jolly good fun)?
Offer the cake (as in "toss it in their direction") and know it won't make a difference....
WWYDI your sisters were treed by Maugrim?
Kill him with the weapon I received from Father Christmas (a few turns ago)
WWYDI you were locked in your cabin (on a boat) and it was sinking?
Panic! Then try to break out. 😛
WWYDI a siren was luring your ship into the rocks?
Get everyone to the lifeboats!
WWYDI, today, you found out that you were adopted?
Be really disappointed that my parents are only telling me this now at the age that I am. And then realize that maybe that's why my mind works differently (eg: they're math/science minded and I'm definitely English-minded). 🙂
WWYDI you randomly found money in your mailbox?
Wonder where it came from and talk to my parents about what I should do with it. I would probably end up giving it to God.
WWYDI you met Susan Pevenise in the flesh, here on earth?
Um, resist squeeing so I didn't freak her out, and then ask her if she still believed in Narnia.
WWYDI if Susan said no and said she didn't know what you were talking about?
Hmm...find out where she lives, organise a weekly lunch with her and gently guide her back to Narnia, perhaps by dropping subtle hints.
WWYDI you found Lucy gagged and bound in the woods with a Telmarine guard standing over her?
Rescue her! Unless of course, it was a strategic ruse and she didn't want or need to be rescued.
WWYDI you were caught by the Telmarine guards while trying to help Lucy escape?
Freak out and then try to get back to Cair Paravel to get help!
WWYDI the Telmarine guard grabbed you, then bound and gagged you right next to Lucy?
Really hope that this is supposed to be a ruse and help really was on the way ("or perhaps even at the door as we speak", to quote Trufflehunter).
WWYDI you and Lu were left in this situation all night alone in the dark?
Well, I'd probably try to start saying comforting words to Lucy through my gag. I'd try to move around to keep warm, maybe attempt a few hours sleep. I'd most likely start a tune (humming of course, I'm gagged!) to keep my spirits up.
WWYDI you were about to be killed by the Telmarine guard, who had already mortally wounded Lucy?
