Can you keep a secret?

They seem normal. . .

It was 7:30pm and the main six and Flash left their hotel. They quietly made their way to the woods outside Maretropolis. Treaty Sweete walked out on them with Flare Sparks at her side.
"Please princess, you really mustn't go."
"The only way to see what's so bad about them is to go to the source." Twilight tells her.
"Ooh I hope they have cake!" Pinkie squealed. Fluttershy agreed.
"Ok then. Just be careful. I'm keeping. Flare with me until this mess is over." Treaty says taking Flare back into her home.
"Won't they get suspicious and come to your home?" Rainbow Dash inquired. This made Treaty think for a minute. She continued into her home.
"They can try taking him from us, but not on my watch!" She shut the door.
"Oh my, somepony's got trust issues. . ." Rarity says.
"Can't argue with that." Applejack agreed. The ponies made their way into the woods.

While walking down the path they came to a big house with lanterns and tinted windows so you couldn't see in. It had a somewhat ominous feel to it, a bat flew by and in through the chimney.
"It's definitely got a theme to it I suppose." Rarity says unsure.
"I think it's lovely, everypony has their own hobby after all." Fluttershy inquired. Flash rolled his eyes at the idea of this being a hobby, but an interest. Twilight knocked on the door. Ellei answered it.
"Oh hey you came. Come on in, the others are already here."
"Others?" Flash asked. They entered the house and were astonished by what they saw. There were bats on the ceiling and streamers dangling. A pony with black shagged hair was talking to another with a green cap on his head.
"Who are those two?" Twilight asked.
"That's Crimson Slash and Gamer Stats. Crimson is mine." Ellei explains as she walks up to them. She whispered something to them and they laughed.
"So this is the princess of friendship. You and your friends seem nice . . . So far. . ." Gamer says the last part under his breath. His eyes seem to flash red at the comment.
"This one seems a little self centered if you ask me." Rarity whispers to Twilight, she nodded. Flash walked over to the staircase to get a peek. Then he asked, "Where's Scarlet?"
"I'm right here!" She says from behind the staircase, "I was just checking on our friend in the basement, he's really shy."
"Why is he in the basement?" Rainbow asked suspiciously.
"He finds it more comfortable down there that's all."
"I think it's nice to respect another's privacy" Fluttershy says.
"Is there cake?! Let's party!!" Pinkie says anxiously.
"Not a problem! Let's get this party started!" Ellei says starting up her stereo. The music boomed and the strobe lights went off. Everyone began to dance and have fun. Twilight looked over and noticed Flash head upstairs. She followed after him.
"Flash! It's rude to come up here without-"she was cut off by what looked like a portrait. It was Scarlet and Ellei with those two other ponies and someone else, he was holding something, it looked like. . .
"It's his crown." Flash says looking at the portrait.
"Who is that other pony do you think?"
"It's EJ." A voice said from behind them. Scarlet and Ellei stood there their eyes were completely black with red glowing pupils. Twilight and Flash jumped and held each other at the sight.
"You shouldn't have come up here."
"We found King Sombras crown when we visited the crystal empire." Ellei explains.
"My special talent is keeping secrets for other ponies, and my own. I think I'm about to make another one." Scarlet says. She used her magic and threw Flash against the wall, knocking him out. Twilight went to fight back but a presence of another being caused her to go unconscious. . . Last thing seeing was darkness spreading. . .
