Twilight Sparkle had just become an Alicorn and was spending time with Princess Celestia in Canterlot to acclimate herself to her new form and responsibilities.
As Twilight went about her studies, Spike found himself growing lonelier-and-lonelier. The only time he got to spend time with Twilight was at night. Apart from the whole, "How was your day?" conversation, this time was typically spent writing letters and creating checklists for the purple Alicorn.
One night, Spike sat up in bed and looked at a picture of Rarity in which she had given him to remember her by while he and Twilight were away in Canterlot.
"Oh, Rarity," he sighed. "I miss you so much"
He got out of bed and began to pace about the bed chamber in which had been given to Twilight. He eventually made his way to one of the windows and looked out at the horizon.
"My dragon code says I should be here for Twilight," he said before looking at the picture again. "However, my heart says I should be with you."
Twilight was fast asleep in her bed. The amount of effort she was putting into understanding her new form and responsibilities made her fall into such deep rests that she had to get an alarm clock just to make sure she didn't sleep past the crack of dawn.
Spike looked out at the stars again and was quite surprised when he noticed what could only be Princess Luna making her way towards him.
"Thou art restless, little one," the moon princess stated as she flew up alongside the window. "Your dreams have told me much and we have come to aid thee in your quandary."
"My dreams?" asked Spike as he opened the window.
"We have seen you dream," she said. "We have seen the torment in which thou art suffers over the passion thou art feels towards the one known as Rarity."
Spike blushed.
"We mean to bring you no shame," she said. "We merely wish to assist thee in attaining peace of mind."
Spike looked towards the slumbering Twilight and back at Luna.
"I'm conflicted," he stated.
"This is quite apparent," replied Luna. "Would thou art please show us this amulet that thou has dreamt much about?"
Spike gasped.
"The, amulet?" he asked.
"Yes," stated Luna. "The one that would grant thee the ability to achieve love's true form."
Spike checked to make sure that Twilight was still asleep before using his magical powers to belch out the Amulet of Love's True Form.
"Ah!" stated Luna. "So it is this bauble in which has troubled thee so much as of late?"
"Yes," said Spike. "I've had it for some time and have kept it hidden away."
"And why is it that thou art has not used its magic to attain thy deepest desires?" asked Luna.
"Well," said Spike as he looked at the amulet. "I guess I've been just too afraid."
"Afraid of what?" asked Luna. "Rejection? Twilight? No longer being that which is what you believe yourself to be?"
Spike said nothing.
"It is thy destiny to use that amulet," she stated. "Only through it use will thou art truly attain the peace of mind thou art desires."
"But," said Spike as he looked to the Amulet of Love's True Form. "What about Twilight?"
"Dear Twilight will be fine for she is under our sister's care," stated Luna. "It is now time for thee to meet thy own destiny."
Spike looked deeply into the amulet. It's jewel starting to glow an eerie green as he did.
"Allow us to assist," stated Luna as she used her Alicorn magic to activate the artifact. "Now place it around thy neck and allow love's true form to become thee."
There was an ethereal, greenhaze around the amulet as Spike put the mystical item around his neck.
"What the?" he asked as he felt his body begin to tremble, twitch, and stretch. "What's going on!"
"Love's true form," stated Luna in a way that didn't quite sound like Luna.
"What's… Happening… to… meeeee…" groaned Spike as he his voice grew deeper-and-deeper and his body started to enlarge.
Luna laughed at the sight before suddenly bursting into a puff of green smoke.
"You shall be the key to my conquest!" cried a pony who appeared quite tattered and torn. She had wings, but not like those of any Pegasus or Alicorn.
"Wa-wa-wait!" cried Spike as wings suddenly burst out from his back. He then let out a deafening roar as he leapt out through the window after the frightening pony who had masqueraded herself as Princess Luna.
Spike's roar was enough to startle Twilight from her slumber.
"Spike!" she cried as she leapt from her bed. Her number one assistant was gone.
"SPIKE!" she cried upon noticing how one of the large windows appeared as if it had been forced through.
"Princess!" cried a pair of guards as they burst into Twilight's chamber.
Twilight found the picture of Rarity that Spike kept with him lying near some broken pieces of the window. "Oh, no," she said as she looked out the window. The silhouette of a large dragon flying off in the direction of Ponyville could be seen just off to the horizon.
