"This was it... tonight, was going to be the best night ever..." Lilly couldn't help but chuckle aloud to herself as she woke up about half an hour before sundown, when it would be her time to lower the sun completely and then bring forth the night she so loved to adorn with her most beloved stars and designs. However... her primary duty was not what particularly excited her tonight, it was moreover the date that had given her the giggles. For weeks she had planned some sort of "revenge" against her sister, some sort of plot to make her pay for what she had done in the past... and once the clock turned midnight, and the calender flipped to the first day of April, all bets would be off and Lilly would begin preparing her most cunning prank yet.

"Oh Lilly... you are a very sneaky mare... who else better to prank than Katey herself?" Once more, Lilly found herself getting rather giddy as she trotted out of her room and out towards the designated balcony where she would help lower the sun and then start her wonderful night. Oh, it will be so wonderful... Lilly thought to herself. It will be the most amazing night ever... I simply can't wait!

All of Jasper was now long into the night, the thousands of stars above lightly sprinkling their eternal light upon the sleepy world below. All the little cubs had gone to bed, the lights in the castle had almost all gone out, and only the sounds of crickets could be heard off in the distance, bringing a natural sort of chorus that set such a calm in everyone who listened to it. Everyone was either asleep, relaxed, or enjoying their time out in a field enjoying the wonderful lights from above... all, except for one crystal white, deliciously mischievous wolf up in the Alpha's Den in Jasper.
Lilly worked in her room by herself, multiple spell books she had stolen from a mysterious wolf lay open around her as she sat in front of her desk, looking through the open spell book before her. The book was rare, and contained magical spells and incantations that no wolf would ever be able to make sense of. Lilly, however, was more than able to read through the complex arrangement of symbols and words before her. Finally satisfied with the information gathered, Lilly closed the book and proceeded out of her cave, a wild grin plastered on her face.
As she slowly trotted through the hills, her eyes were dimly lit as the moon shined against them. With the last bits coming into place, Lilly turned a corner to a cave which Humphery had tried to make look "cool"as he called it. This was where her spell would be cast, this was where her ultimate prank would begin, and this... was Kate's den.

Normally there would be a few guards at the foot of the den itself, but Lilly had ordered them earlier that night to take watch at a post a bit further out, a post from which she could sneak by easily and gain access to her big sister's chamber of slumber.
Slowly, quietly, she gently pushed open the large door and took a quick peak around the room, making sure all was still and unexpecting. Gradually she began to slip inside, first her right foreleg, then her left... using her tail to keep the door slightly opened... next her back legs, and finally her tail... after which she slowly closed the door behind her, making the door shut without even the slightest peep. Everything was going according to plan...
Lilly approached Kate's bed from the side, a large lump under a pink comforter.
     Her eyes were still dimly covered by the soft glow of the magic she had conjured and set in place, ready to be unleashed at any moment. Lilly looked around one last time, inspecting her surroundings to make sure she had not forgotten anything essential to her plans. Lastly, she closed her eyes and thought deeply, imaging her bedroom very clearly in her mind, hopefully enough to be able to teleport out of the room quickly once the spell was cast. It was all ready now... it was time to pull the ultimate – and probably most embarrassing – prank that Jasper had ever seen!

This spell has been one heck of a pain to finally get ready, Lilly thought to herself as she looked over her sleeping sister. But now it is time for the greatest night ever... Katey, my loving sister, I always wondered what sort of embarrassing secrets you may be keeping secret in there... but, it would be so selfish if I were the only one to find out about it! No... I think that this Psychosurreliac spell shall let everyone who gazes upon you to know all the things you keep tucked away... perhaps a childish desire? A little stuffed Teddy you cuddle with every night? Maybe you have a craving for a rather ghastly food, or even... Lilly gasped to herself lightly as the sudden realization hit her. ...or even a CRUSH! Ooooh yes, big sister, tonight will be a night to remember...

The spell Lilly had been researching for hours and piecing together in her eyes was no normal spell. It was a highly advanced, incredibly difficult spell that – if cast improperly – may result in side-effects such as temporary memory loss, sporadic changes in mood, "Derp" syndrome, or even mental breakdowns. The spell was very similar to a truth-telling spell, but instead of forcing the one the spell is cast on to only tell the truth, it forcibly brings out the hidden feelings of the  wolf the spell is cast on and makes them practically broadcast them out to the world around them. Though the effect would only last a few hours, Lilly was sure she would cherish every moment of Kate's mindless babbling and spilling of all the beans she had stored inside of her.

Lilly was completely ready to see her best prank ever come to life... but as her horn flared and the beam of light shot towards Kate, the next few seconds would vastly change her opinions on her recent actions...

The spell struck perfectly, and the mind-altering magic quickly began to seep through Kate's coat and skin, traveling deep into her body and her mind in order to see what it could unravel. All Lilly had to do was channel the spell for the few short seconds it took to complete, and then teleport out before Kate realized what happened. However... only a second into the spell, the magic hit something inside Kate that Lilly didn't expect. It was a barrier of some sort, a seal within her own mind, something that was artificially holding back something else inside of her older sister. Whether Lilly wanted to find out what it was or not, the spell moved too quickly for her to make any changes in it.
The powerful effect of the spell almost instantly broke through the hidden seal inside Kate's mind, unleashing whatever was secluded inside it. But at that moment, the magic that was holding the seal in place suddenly expelled itself from her mind violently, pushing out Lilly's own spell as Celestia herself was hit with an inward jolt up and down her spine, immediately waking her up with a heavy, dry gasp. The spell ended that second, and Lilly knew something was wrong... the spell was cast perfectly, but something inside, some other magical effect inside of Kate had not only stopped it, but completely expelled the effects and had even woken Kate up!

Oh no, this is bad... I have to go, I have to get out now! Before Lilly had even taken the time to think about what may have caused the abrupt interference of the spell, she dove into her mind and brought up the image of her room, quickly conjuring up a quick teleportation spell and sending her out of the room.

Kate, hearing the light Ping that is the sound of a teleportation spell, thrusted her upper body upward and looked around the room hastily. Nothing was there... the room stood dark and still, and only the sound of the wind blowing against the drapes of the windows was able to be heard. Kate sighed deeply, closing her eyes for a minute to think about what may have just happened. Was she dreaming? Did she perhaps have a nightmare and her horn was on the fritz again? She couldn't tell, but in moments the door to her bedroom opened up as two wolves, Hutch and Can-do stepped in, looking to be as if in a rush.

"Katherine!" Hutch announced. "We saw a bright flash coming from your den, is everything alright?!"

"Well of course, everything's just..." a sudden jolt seemed to impact Kate as her eyes suddenly widened, her pupils dilated harshly, and her teeth began to jitter. She looked down at first, her mind scrambled and her regular thought process interrupted by this strange sensation she was feeling. She suddenly felt dizzy, her head lightly swaying side to side as something began to invade the workings of her mind.

Hutch and Can-do, seeing the apparent disarray of the Alpha, rushed up against the foot of the bed, seeing if the Alpha was injured or perhaps giving off some sort of magical backlash, as would be the effect of most offensive spells. Yet the Alpha's swaying quickly stopped, as she then looked up towards them, meeting each of them eye to eye.
Both of them took a step back. This... wasn't the regular gaze of Kate. Her eyes were open wide and her pupils were now resembling tiny black dots. Little streams of blood seeped into the whites of her eyes, making them seem bloodshot. Her face had a horribly creepy grin on it as her teeth continued to jitter and shake, as if she was freezing cold. Kate's eyes shot to each of the wolf guards quickly, going back and forth to meet with both of their eyes.
Before another word was spoke from the guards, Kate's eyes lit up and the door behind them shut with a loud thud. The lock on the door shined magically as it slit into place, sealing out anyone outside and trapping any others inside with what now lurked in Kate's bed. The two guards looked back at the closed door, then to each other, both with obvious strikes of fear in each other's faces. They didn't even begin to remotely understand what had happened to Kate, what had happened in the room before they came in, but she wasn't her now... she was, something else... the look on her face sent shivers through their bodies as her eyes seemed to pierce like the tip of a spear into each of their souls. Neither guard could move as Kate gazed at each of them, her grin widening while the sheets on her bed began to slide down by her own magic.

"My loyal, most trustworthy guards..." Kate finally spoke, her voice piercing through the silence of the room. "Would you care to join me... tonight... in a most wonderful slumber?"

"K-Katherine... are you alright? You seem rather... shaken...",          Said Can-do.

"Oh, I was feeling very lonely earlier... but now that you both are here, I now have something to keep me occupied..."

A magical force on the rumps of both guards pushed them towards the bed a little.

"W-we really should... ya know, get b-back to... standing g-guard, ma'am..."
Said Hutch.

"Oh I think you've done a fine job tonight... but now it's time for another duty of yours..."

The magical force tugged their bodies closer to the bed, halving the distance from where they started.

"B-b-but Katherine! Wha... what other duty is there for us, y-your majesty?"

"Only the most important, most taxing, and most pleasurable duty of all..."
