What would your MC do if...

Oh whoops!

WWYMCDI they were a movie star?

Captain Olmsley Friar would do a remake of the Hunt For Red October... set in space.
Lily would kill people, as usual. Rose would try to get with every single male film star in hollywood. Violet would stop her.

WWYMCDI they found themselves trapped for several days on end in a small building/boat/spaceship/cave etc?

David would try out spells to blow up the place which would fail in the end no doubt.
Jacob would radio for help then set explosive charges all over the building to blow it sky high! FUN EXPLOSIONS!

WWYMCDI they switched bodies with their significant other? eg boyfriend/girlfriend

...Well...Considering that there is absolutely no noncrack pairings in mah book...The above wouldn't really happen.
However...Just friends wise, and I believe that this would still be wicked lulzy, T.Mor in Riddle's body..."WHAT DO YOU MEAN....YOU BREAK YOUR RIBS EVERY MORNING....FOR THIS CORSET?"
Yeah...He'd just flip out...Awkwardly. Of course.

WWYMCDI they found themselves in an existential quandry?

They would'nt know... mostly because I don't know what an existential quandry is...


WWYMCDI they found themselves in the Harry Potter universe?

Uh... Jay would train hard at Hogwarts, Kay would just assume she was totally crazy... as always... and Marley would fly around on a broomstick, slap Voldemort, and try not to die...

WWYMCDI they were forced to go skydiving?

That's actually happened a couple of times. Without a parachute. They'll be fine.

WWYMCDI they were stuck in a room indefinitely with someone they hated?

Uhm...continue with daily schedule...Lather, Rinse, Repeat ad nauseum for T.Mor... Or if the hated person in question WASN'T Mr.Face...possibly do a little bit of ranting before sitting down on the other side of the room and pretending they didn't exist.
Riddle...well...Is she ARMED AND LEGGED? because I sense chopsticks in that person's future...well really depends on the person I guess. Maybe she'd get out the peanut butter chainsaw. Or she'd forget who the person was all together, and simply eat whatever she had in her pockets, oblivious to the fact that she was suppoused to be hatin'.

WWYMCDI Their entire 'verse suddenly turned into a musical?

Andrew well.....possibly would go along with it...then again so would Tommy. *pictures them singing and dancing in the street* Oh...boy....Ezra...would hate it. He'd probably be stuck in a corner banging his head against a wall.

WWYMCDI They were trained to be ninjas?

MEgan would fall on her face because she is so freaking clumsy. Artemis would get pissed off hahaha and most likely use her magic water powers to freeze the instructor and all the other ninjas *Pictures this and laughs* Jace would just say "SCREW THIS!" And walk out. Angela would train to be ninja and try to prank Jace with it.

WWYMCDI if they were at disneyland

Hm...
Nikkie would beg to ride all the rides and buy a souvenier.

WWYMCDI he/she was photographed by a stranger while he/she was peeing in a bush? (Preferably a male protagonist.)

T.Mor would be...very confused. There are no bushes in Auda...or cameras really...so the presence of both, would be more perplexing than the event itself for...quite some time, Probably until August explained what had just happened. And then 'Awkward Awkward Awkward' would continue to happen, as there's really no scenario when he's NOT awkward, along with some kind of like...embarrassment. Yeah.

WWYMCDI they had to substitute teach a middle school class for a day on earth?

Vanquish would spend the morning on the Ideal Gas Laws, and spend the afternoon trying to get them to debate about the respective qualities of different types of steel.
Kraf Ventrix would burn the hellish place down and walk out of the ashes.
Cabion would spend the entire time telling stories.

WWYMCDI They woke up in a silent movie?

Jacob would start shooting and listen while his bullets didn't make a sound.

WWYMCDI they woke up on the moon? (In like a space suit so they wouldn't be like dead or anything)

Vanquish wouldn't see anything strange about the situation. He's probably there for a week's holiday, or he's temporarily on loan to another facility to fix something. The only novelty would be that he was actually living in noticeable gravity again.
Edgar would be a bit surprised. He almost never goes to the moon.
KAT would absolutely freak. She's a piece of software, so the idea of unconsciousness or owning a body are utterly alien to her.

WWYMCDI they realised that they couldn't speak?

T.Mor would quite possibly be a bit better off, as his speech patterns are... Somewhat... Ellipsisy, shall we say. It sould take off the pressure of having to actually say something coherent.
Riddle would absolutely freak out... As well... CAPSLOCK is typically her preferred method of communication. Then she would forget that she needed to yell about antipasti, and it would all be chill.

WWYMCDI if they awoke to find bananas everywhere?

Nameless would be pretty confused then he'd relize...oh wait...FREE FOOD! Yeah, then he'd have to steal less.

WWYMCDI They were the next batman/batgirl?

Dan would be confused since he is already a superhero.
Kiera, Rogue, and David would both not know who batman or batgirl are.
Jacob would refuse he has enough to deal with killing vampires and werewolves.

WWYMCDI they were in a zombie apocalypse scenario?

The zombies are now on fire. And...you know...screw the zombies anyway. 'Cause they can't fly.

WWYMCDI they were trapped in a cave with no foreseeable escape for several days?

I missed the zombie one! The Marshall's gonna sulk now...

Marshall Wade would blow the place open. Or just suck it up. In fact, knowing Wade, he'd find some goddamned zombies in that cave and shoot them where it's gonna leave a mark.

WWYMCDI they had no hands?
