Do I Look Happy?

9

A shiver coursed through me as the granite doors shut behind me. I have no idea what happened back there, but one thing is for sure, that was not my sister, that was a monster. A monster who looked like my sister, walked like my sister, but it was not my sister.
I began to trot towards Starswirled's living quarters. I opened the door and the blue unicorn jumped making papers fly everywhere.
"My aren't you early!" he laughed as he straightened his spectacles with his magic.
He looked at me and his tone changed,"My dear, what's wrong?"
"Its Luna. She's been acting strange." I explained.
"How would you describe 'strange'?" he asked sitting down.
"Well, she snappish towards me, short tempered, and dreaming about ponies I don't know!" I answered.
"Hmmm," he thought hard,"My dear Celestia, I believe this is nothing but a little mood she's going through because she believes nopony watches the night. I wouldn't get worried." he said reassuringly.
I nodded my head, but I was still worried about Luna. This was not her, this was a monster.
