"Good evening Ms Velvet and Mr Light." Celestia smiled serenely at the two unicorns.
"Good evening Princess Celestia." The two answered bowing.
"Now now, no need for that." Celestia smiled. "I just wished to talk with you about your daughter."
"Oh no, is Twilight in trouble?" Night Light asked.
"You could say that." Celestia answered sipping on her tea.
"Have some tea, please." She offered the two unicorns.
"Um, no offense but if there's something wrong with our daughter I feel we have the right to know." Night Light said firmly.
Oh, of course you believe you have the right to know! Celestia thought to herself.
"Indeed, but the news is not good, and this tea is a very special blend that will allow you to process this much better and handle the situation appropriately."
"Hey Auntie! Oh hello Night Light! Hello Twilight Velvet!" Cadence smiled warmly.
"Cadence! What are you doing here?" Night Light asked as he and his wife drank the tea forced onto them.
"Oh, Auntie and I just have some questions for you." She smiled. "You see, Twilight Sparkle, your beloved daughter Twilight Sparkle, was recently put in the hospital, apparently she poisoned herself with a very very toxic plant that she really should have, and did know better than to eat."
"Oh... oh... my baby!" Velvet cried.
"Oh indeed, it is awful." Cadence sighed. "But, well the effects of ragwort, it causes stomach twisting, fever, hallucinations, nightmares, and well, Aunt Luna saw some very interesting things in Twilight's nightmares. Things she knows actually happened, that tormented that poor mare for many years."
"Oh nonsense!" Night Light shouted. "Nightmares are just that! Nightmares! Twilight had a wonderful life growing up!"
"No, they are not Night Light. And you seem quite defensive without knowing the content. Guilty conscious?" Luna hissed into his ear, startling the stallion so badly he fell out of his chair. "For you see Night Light, Twilight Velvet, there is in fact a distinct difference in forms of dreams. Of course you have your normal dreams, dreams of everyday events, or silly things, then you have your dreams that are comprised of your hopes and desires, then there's the ones comprised of your fears, usually nightmares but not always, and there's also a very special class of nightmare, one that is commonly found in soldiers, and victims of rape, assault, and abuse."
"These particular nightmares are memories my little ponies." Celestia said. "Memories tainted and nightmares brought to life merged into one awful thing generally known as a night terror. These night terrors are quite common in children, but always fade out with time. However, as Luna said, those who have suffered great trauma will often continue to have these night terrors. Now apparently Twilight was reliving some very traumatic things, usually involving her brother and father. Though sometimes aided by her mother."
Night Light shrank in his seat.
"Now, are you still going to lie to me?!" Celestia shouted into his face.
"I suggest banishment!" Cadence piped up.
"Heavens no!" Luna exclaimed. "Nothing deserves this filth."
"Nothing but the caves beneath Canterlot?" Cadence suggested.
"Perfect." Celestia grinned wickedly.
"Terrible ponies rot in the crystal caves to atone for their sins." Celestia laughed manically. "You see, you're actually quite lucky Twilight's therapist and friends are the only ones besides us who know. Ponies don't take too kindly to those who touch innocent fillies inappropriately, particularly not ones who do it repeatedly, and especially not when it is that filly's very own parents."
A flash of white and a cut opened on Night Lights cheek. Together Celestia and Luna broke the horns of the unicorn couple, it would not due to have them have any way of escape. Screaming could be heard, but like good guards, nobody intervened, since it did not sound like their princesses, they assumed it must be a pony deserving of punishment.
Celestia pushed Night Light to the ground, while Cadence held down Twilight Velvet.
"So, how does it feel being tormented?" Celestia asked, smiling serenely.
"Stop! Stop! We're sorry!" The mare screamed. "Help! Somepony!"
"Oh they can't hear you." Cadence laughed.
"Goodbye, my little ponies." Luna flared her horn, there was a flash, and the spot Twilight's parent's occupied was empty, Celestia and Cadence fell to their faces at the disrupted balance.
"Awww. Lulu, I wanted to torment them some more." Celestia pouted. "It was quite cathartic."
"Yes, but it doesn't look good on you sister. Besides, I think Twilight would probably like to see her mentor again."
"She's awake again?"
"Indeed. She was dreaming of better times with you, so I think maybe you should visit."
"I shall then. By the way, where did you send them?" Celestia asked.
"The deepest pit of Tartarus, obviously." Luna answered brightly.
"Even Tirek wasn't put that far." Celestia mused.
"Of course, Tirek was evil and power hungry, not psychotic and getting his rocks off by tormenting an innocent filly for sexual reasons."
