Having caught her breath, Twilight trotted up to the cottage proper, and took a moment to glance around. The animals stared back, unblinking, in a rather eerie dead silence, their heads turning in unison to follow her movements.
Well... that didn't at all set off any warning bells. What she had taken for peace suddenly seemed more ominous, and Twilight's hopes that Discord had skipped on Fluttershy's house went out like a candle in a storm.
Worry seeping in once more, Twilight couldn't help but let her overactive mind start bringing up worse and worse potential scenarios for what was going on.
Maybe Fluttershy was injured up in her room, and had locked up the house to prevent her animal friends from taking a second bite out of her. She could be in desperate need of first aid and a trip to the Hospital, bleeding out right at that moment!
Thus, there was only one thing to do - Teleport right into Fluttershy's room and make sure things were okay.
Turning her mental focus to bringing up an image of her friend's bedroom, Twilight sent a quick pulse of magic to make sure her landing spot was clear, and then vanished from the yard in a flash of magenta.
Her sight was instantly shrouded in darkness as she landed in the room, and at the sound of rustling fabric, Twilight lit her horn to allow her to see. There was Fluttershy, right in her bed, wrapped in her sheets and struggling with them to free herself to react to the sudden intrusion to the room. However, even in the dim purplish-red glow of her magic, Twilight could see something that wasn't quite right about her friend: Fluttershy's appearance was more ragged than normal, in an almost feral way that uncomfortably reminded Twilight of Spike right before his attack. Then there were the leathery bat-wings, the hint of pearly white and wickedly sharp fang, and the glimpse of her cutie mark - altered from the normal trio of butterflied to a set of red bats.
Suddenly, several things clicked in place in Twilight's mind at once. The shuttered windows keeping out any light, the unnatural look to the animals in the yard, and Fluttershy's appearance all taken together was a perfect fit for an old vampony tale... and Twilight had just stepped into her lair.
Adrenaline rushed as Twilight's fight or flight instincts woke up, and were promptly bashed into unconsciousness by new instincts that didn't have that pesky flight option in them.
She's going to attack you. She'll bite your neck and drink your blood, and leave you dead, enslaved, or worse. That's what Vamponies do; it's what monsters do.
It's you or her now. Attack. Attack. Eat.
She could do it too, with her magic. She had magic to change things' shapes; apples to oranges could probably be altered to be used for ponies to oranges. She could turn herself into a predatory monstrosity with little trouble if she put her mind to it. But no, she wanted to eat Fluttershy whole; to have her struggle helplessly inside of her. A simple size alteration spell, and the predator would be the prey...
