What would your MC do if...

Die. The exact length of time taken would vary somewhat, but would generally be around two minutes for all of my characters.

WWYMCDI they did something they find morally reprehensible... and enjoyed it?

Dan would probably shrug it off and go on with his life.
David would embrace it and try to see why he thought it was wrong and to see if he needed to change his point of veiw.

WWYMCDI they had to eat their significant other? Like their BF/GF?

Cassie couldn't do it...she could never eat Evan.

WWYMCDI They were thirty feet tall?

Dan would use a spell to shrink back to normal size.
David would spazz out and die because he would probably bust a hole in the Pride of Seraph killing the entire ships crew.

WWYMCDI they met God and the Devil?

Apologise.

WWYMCDI they met the president of the US?

(Lol Jacky xD Apologize for what?)

Peter (though it works for any of them, really...just sans the polytheistic oaths for Sarah and Nike):
Try to think of his name.
Godsdammit, it's not on the sheet! Agh, um...ah... Wow, I feel dumb. Oh! Um, it should be on the data-pad...and now I feel dumber. Okay, what plane is this...?

WWYMCDI they had an opportunity to kill the person they hated the most?

Billi would take the chance in a couple seconds flat. It would equal her freedom forever and give her a chance to find out her past.
Ember probably wouldnt, because she couldnt bare to accidentally or purposely kill someone else.

WWYMCDI they got to meet Darren Criss? (if you do not know who he is then you are totally disowned....He was Harry Potter in A Very Potter Musical/sequel or Blaine in Glee.)

Dan would curse him for being in Glee and both of my David's would not know who he was David from one book was too far in the future and the other is in a different medeval world.

WWYMCDI they were told to kill the political leader of the country?

Tony: N/A. The plolitical leader is almost certainly dead anyway.
Hannah: Do it. definitely.

WWYMCDI they were stripped of any magical powers and/or awesome abilities?

Dan would be seriously angry because he couldn't be with Stella any more but he would figure out all she had to do was bite him to make him a werewolf again.

David would get better at sword fighting.

Other David would get better with his gun.

WWYMCDI they found out they were a god?

Regret's question: Liz wouldn't be able to be with Andrew. Ezra would be glad...sorta.

Condog's question: I don't know...

WWYMCDI they we're a ghost?

Dan would spazz out because his entire life would be very confusing, both Davids would probably do the same.

WWYMCDI they turned into a dog?

Chase cars, hump someone's leg. You know, dog stuff.

WWYMCDI they woke up to find that they were a zombie?

(lol love you're answer Regret)
Even though Andrew's incorrpul he wouldn't be happy about it.

WWYMCDI their gf/bf died?

Be heartbroken. Isn't that what usually happens when people close to you die?

Along those lines, WWYMCDI their gf/bf was forced to watch them die?

Andrew would be really upset even though it means he an Liz could be together. He doesn't want Liz dead.

WWYMCDI They were kidnapped?

(I'm not talking about what Andrew would do if he had to watch Liz die; I'm talking about what Liz would do if Andrew had to watch her die. How Liz would react, not Andrew.)

Shift out. Pfff.
However, if there were Sybek around that could sense it, my characters would have to find a way to break out instead.

WWYMCDI they were lost in a forest?

Tony would think nothing of it. He's always lost.
Kraf Ventrix would burn the hellish place down and walk out of the ashes.
Hannah would simply bring the airship over the forest and use that to get away.

WWYMCDI they came face to face with their personal hero?

WD: Liz wouldn't want him to see her die, she'd worry more about him then hersef.

Dan would be all chill and be like, "sup". David's jaw would drop because his own personal hero is dead, his bro John. and other David doesn't have a personnel hero.

WWYMCDI They woke up and found that they were 80?

Uh... Marley would be like "THE FREAK?! I'M A VAMPIRE, WHAT IS THIS CRAP?!...Does this mean I can't steal stuffs without throwing my back out?! I want a refund!"

WWYMCDI they suddenly got amnesia?

Cassie would be upset because she couldn't remember anything. Evan would try to figure his past out.

WWYMCDI They were given clay, paint, and sculpting tools.

Riddle: MAKE A SUBMACHINE GUN OF COURSE.
T.Mor: Sell it for the food money.

WWYMCDI if they had a really obnoxious person sitting on the train next to them for an extended train ride?

(Lol Riddle)

Tommy: Smack them.
Evan: Deal with it.

Gh, you forgot to suggest one!
