(Well, back again? Good! Let's carry on with our story, shall we -o- curious one?)
Dash looked very puzzled at me ....well, so did the rest of the Mane Six. I was shivering like a Chihuahua.
That's when the voice said "Hey! You're making me look like a scaredy cat!" (well I'm sorry voice in my head) "Lighting Dust - my name's Lightning Dust." said Lightning Dust (right Lightning Dust. You should know they turned a creature of chaos into literal stone!!!)....
"Ok, that is something to be afraid of." said Lightning Dust. I then blurted out loud "don't turn me into stone! I’d make a really bad statue!" the six mares started laughing...was that funny? I'll give then something funny. I then jumped on the table and started doing a stand-up comedy act.
"And what's the deal with timber wolfs? They are wolf and they are timber but where is their brains?!" I said. They were laughing up a storm. I decided to stop before I got off track
"Listen girls I'm not actually Lighting Dust." They let out a little chuckle "No seriously, I’m not her. I'm from another dimension." I said.
Then Pinkie said "Like from the mirror!"
“Exactly! But sort of not” I said leaving puzzled looks on their faces.
Applejack then said "Then who are ya?"
I then said "Carl. Carl Dustway".
Then Dash said "but Carl's a stallions name...and you're not a stallion".
I then said "I was." A blush came over all of their faces. ”You"re a stallion!?!” said Lightning dust (well sort of.)
Then Spike said, "wow that must be rough." I saw Twilight elbow Spike letting him knowing not to talk about that.
"Y-yeah. It is" I said. Twilight placed a hoof on me and said "it's ok, we can help you ....right girls?"
All the Mane Six said "yeah!"
“Thank you Twilight.” I said.
“You're welcome Light-...Carl.” said Twilight giving me a hug.
“Your mane smells nice” I said
“um...thank you?” Twilight said.
Your really jumping around with just this chapter alone. Try giving more details about how somepony is reacting, like say Pinkie Pie was clutching her barrel and leaning back as she laughed. Try not to keep things so simple. And you don't need to have these chapters so short either, just trying to be helpful I'm not trying to put you down or anything.
