Armored Encasement

"This isn't a joke, is it?" She asserted.

"No, Twilight. You have to believe me, please sis." He answered, the word 'Sis' came out of his mouth when he hadn't said it.

"...Sis?" She repeated.

"I think I still have some of Shining's thoughts, this isn't my body Twilight!" He raised his voice a bit.

She shushed him like a librarian would. He stared at her, dismayed.

"Twilight, Follow me to Ace's- I mean my house." He stuttered.

"This better not be some trick." She seemed to warn.

They both trotted down the path to his house. He opened the door. They cantered into his bedroom, a still sleeping Ace in bed.

Ace shook himself, no reaction.

"See? I'm supposed to be in this body!" He indicated to the pony on the bed.

"I think I need to do some research on this..." She responded.

She galloped out of his house, into her library, Ace followed behind. she opened the door and sat down on an armchair, opening a book titled 'Spirit Magic'.

She flipped a few pages and read aloud:

"In order for a spirit to return to it's original home, one must be escorted with the spirit to a different plane of existence; one must utter these words; Intrabit in animum, mentem exitus, una duos in planum erit ultra in oculo."

She started closing her eyes, suddenly falling lifeless.

"...Twi?" He nudged her with his hoof.

In seconds after he said it, he fell on his hocks. He then fell on his side. He opened his eyes in a place he couldn't define. He couldn't see anything, yet he felt like he was there before. He trotted aimlessly, until he heard Twilight's voice.

"Ace! It was you in there!" She called.

He followed her voice, still completely blind.

"Twi, I can't see anything." He stated.

"I have to see for you." She said, now very close to him.

He reached a hoof out weightlessly to see just how close she was. He didn't feel anything, but he was aware he was touching something.

"Come on, we need to go." She tried to get him moving.
