I was bored, and I thought about how I would like to be in a speeding car with Xander. And then I wondered how the royal siblings of Nohr and Hoshido would react to being in a speeding car. I apologize in advance for any OOC-ness.
Nohr
"Xander, dear, couldn't you ease up a little on the gas pedal? There's no point in our deaths if we can't take down a few of our enemies when we go." It was mystery how Camilla always managed to sound calm, even when yelling over the noise of a sports car barreling down the freeway at 110 mph.
"I'm experiencing nausea," Leo noted coolly and loudly, as Xander made a particularly sudden swerve to avoid the other cars coming towards them in the opposite direction. "I may retch."
"I forbid it," Xander ordered through clenched teeth. "I'm afraid that it is impossible for me to stop now, or all these other vehicles will make shrapnel of our conveyance. And let it not be mentioned what would happen to us."
"Yippee!" Elise squealed. "I love your driving, Xander!"
"Stop bouncing on the seats, love," Camilla murmured.
Elise sat still and looked around the inside of the car. "What do you think these long cloth straps are for? Look! You can make them longer by pulling them out from the seats, and they get sucked back in when you let go."
"Did you know that because we are moving with this vehicle, if our conveyance came to a complete stop immediately, we would all continue moving at 110 miles per hour - right through the windshield?" Leo asked Xander. "It's true. Inertia would cause our bodies to keep moving until gravity, air resistance, and other forces came into play. I wonder how long we would survive."
"I think we're going to find out very soon!" Xander shouted.
A huge semi-truck was hurtling towards them...
...And Hoshido
"I could have dodged that one much smoother, Ryoma," Takumi complained. "Tell me again why you're the one driving."
"What's more important is why are you driving this fast?!" Hinoka yelled into the High Prince's ear. "If we all die, Nohr will take over before we're cold in our graves."
"A hawk never hesitates before the dive; just strike!" Ryoma yelled back gleefully.
"That doesn't even make sense! Plus, you do realize that the strike culminates in death, right?"
"For our foes."
"These are not our foes, Ryoma! And Sakura doesn't want you to kill anyone!"
"Th-that's right. Please d-don't kill anyone." Sakura's plea was lost in the roar of the engine.
"Oh please," Takumi laughed. "This is way awesome, even if Ryoma has never driven a car before." He turned on some heavy metal music, cranking up the volume, slid open the overhead skylight, and stuck his head out. He stood tall, letting his long, gray ponytail whip in the wind like a flag.
Inside the car, Hinoka and Ryoma started bobbing their heads to the beat of the music. Sakura sighed. As long as they were together, she supposed it would all turn out well.
This is just me trying to get a feel for the characters of FE Fates. Feedback would be appreciated, but it's mostly here for fun. I'll probably be continuing this sporadically, so feel free to suggest a situation for me to drop the royals into, and I promise to give it consideration. :) Azura and some retainers might show up in later chapters, but I want to focus on these eight for now.
Anyone waiting on my other stories, I sincerely apologize for writing this instead, but it was just a sudden thought and I decided to run with it.
