"Okay, that should be the last of you trouble makers," the draconequus grinned as he placed Rainbow Dash in one of the last remaining empty cells. There appeared to be one more empty cell, for whomever might be foolish enough to attempt a rescue. His lair was dark except for a single light suspended from the ceiling -- it illuminated a single small table with a single chair at it and very little else. All six of the ponies had rings on some part of their body to inhibit the use of magic, some of them glowering angrily at Discord. Fluttershy whimpered meekly as she tried to hide behind her mane, cowering in the corner of her cage and looking fearfully at him. The chaos entity took the empty seat, then turned it upside-down before sitting on it.
"Now, now, Fluttershy, there's no need to cry -- I'm expecting a visitor to pop in very shortly," he chuckled. He created a pitcher of water from thin air, then emptied the contents. The water changed into confetti as it was guided into a glass he had materialized from somewhere. As the confetti began filling the glass, it changed form yet again, taking on a dark brown hue and bubbling with effervescence. A fizzing sound emanated from the glass before he drank it, emitting a rather loud belch after finishing it off.
"What do you plan on doing with us?" asked Twilight. Her curiosity had won out over her fear -- she had given up trying to remove the ring from her horn as each time she had tried to do so, a sharp pain jolted her from her magic focus. "And what exactly are you talking about?"
"I plan on keeping you here -- that way, you will all stay out of my way while I take over Equestria once again -- and as for this visitor, well --" he chortled as he snapped two fingers of his lion's paw, creating a blue puff of smoke and a rather bewildered-looking azure unicorn mare to appear from seemingly nowhere. She looked around the room, an expression of terror marring her features.
"Trixie wants to know where she is and why she is here!" she shouted as she locked eyes with the draconequus. An inhibitor ring materialized around the base of her horn after the words left her mouth, causing her to panic at the sensation of her magic draining away. "What? What is going on here?"
"Now, now, don't you worry, Trixie -- my visitor should be arriving shortly," Discord chuckled, causing the already confused ponies to express deeper confusion.
"What, Trixie's not your visitor?" asked a perplexed Twilight as she shifted on her hooves nervously.
"No, no, she's merely bait for my visitor," he chortled. His expression showed great mirth as he took a pocket watch from out of his fur, looking at it and listening to it tick the seconds quite loudly. The ticking noise reverberated around the mostly empty room. "Aaaaaand, three, two, one ..."
Every pony watched, waiting with baited breath -- the suspense was so great, Pinkie nearly fell over herself.
"Oooh! Oooh! Who is it? Who is it?" the pink party pony chirped excitedly, eliciting groans from Applejack, Rainbow Dash, and Twilight. To answer her question, yet another brilliant flash of white accompanied by a blue puff of smoke announced the new arrival. She was not alone, however.
"Discord, release them at once," stated a rather nonplussed Princess Celestia. The look of fear on Discord's face was utterly priceless, eliciting smiles of amusement on the faces of the others. To see his jaw hit the floor in comedic fashion would have been worth the price of admission, though the Solar Princess was not amused by the display. The azure mare accompanying her was likewise unimpressed, her expression seemingly one of grim determination.
"What? How did you find me? I -- I -- I wasn't expecting ... YOU!" he whined. "She," he said, changing his attitude to one of nonchalance, pointing at another blue unicorn mare, "she's the one I was expecting." The other ponies were shocked to see a second Trixie in the same room, the show-mare included. Said blue unicorn mare stuck her tongue out at him and blew him a raspberry. "Be careful where you stick your tongue, little lady -- you might receive something unpleasant on it," he growled before turning to face the Solar Princess who continued to glare at him in disapproval. "Well, well, Celly, what brings you here?" he asked, his grin widening.
"I believe I already answered your question, Discord. Release my little ponies," she replied firmly, her gaze hardening at the draconequus. "That includes Trixie as well," she added as she imposed herself into his personal space, her face mere inches away from his. The second Trixie took a step towards Discord to add emphasis to the Alicorn's admonition, drawing a hesitant gasp from a couple of the other ponies.
"Ugh, you're no fun anymore, Celly. I guess I have no choice," he mused, a mirthful tone to his voice as he snapped two fingers of his eagle talon, causing the cells to open and inhibitor rings to clatter noisily to the floor before they turned into doves and flew away, the flapping of wings echoing through the room. "But mark my words, Celly -- I shall return and I shall have my revenge!" he cackled as he disappeared in a puff of smoke. He reappeared momentarily to quip, "And Trixies -- you'll be my entertainment next time around!" before disappearing yet again.
"Princess, thank you so much for coming to our rescue! But -- how did you know where we were?" asked a very relieved Twilight. "And -- who is this second Trixie?"
