Spike hummed a silly song as he cleaned the last spot of dirt in the table. He double-checked the library. Everything needed to be perfect. After all, it was the day that they will return.

He was checking the windows when he heard the familiar roaring sound. He rushed to the door and jumped to Twilight´s neck.

"Youarebackyouarebackyouareback!"

"Calm down Spike! I was only gone a few hours!" she said.

"A few hours? You left for over two months!" Twilight face went pale. "I was worried sick about you! But a few days after you disappear I found this note that said when you were returning."

Twilight turned over to kill the Doctor with her mere sight. "Oh yeah, I almost forgot..." he absentmindedly said and wrote the same exact note in a piece of random paper.

Twilight decided to ignore that and returned SPike hug when she noticed a figure standing in the kitchen door.

"Princess Celestia!"

The Princess moved forward and Twilight rushed to greet her but upon seeing the sadness on her face she stop.

"Princess?"

"...is true then?" and the Princess almost broke in tears.

"What´s wrong? Princess Celestia..." Twilight tried to reach her but Celestia backed down.

Spike was just as confused as Twilight but before he could say anything the Doctor stepped in. "How?"

"You knew it?" Celestia asked.

"Of course I knew it. The strange thing is that you knew it."

"I heard her...every night, I heard her cry, calling me, begging for me to save her. Oh Twilight!"

"I could ramble about psychic connections across the dimensions but in the end, it will be a matter of you loving her that much..."

"What are you two talking about? I´m right here!"

"No Twilight, you´re not!" and they saw that small glimpse of the true nature of a Time Lord. Under the goofy pony there was a harsh and unforgiving overlord whose orders could not be ignored. "You´re not here. You were taken away, a long time ago. You have to remember."

"I..."

"Please, tell me where she is! Tell me where Twilight is!" Princess Celestia cried.

"I am Twilight! Why are you saying those things?!" Twilight in turn cried, backing down while Spike stood between her and the two other ponies, doing her best to protect her.

"I can´t tell you what you need to say. Remember, Twilight Sparkle."

Twilight didn´t understood what was going on. She just kept going backwards until she hit a bookshelf, a photo album dropped and open at a random page. Seeing the picture of her and her friends at her brother´s wedding flooded her mind with hundreds of other pictures, other sensations, hugs, tears, love, fear, a figure approaching her in the darkness, glowing green eyes, darkness....

"Twilight? Why are you crying?" Spike asked.

"I...I remember. I´m not...I´m not Twilight."

"No, but your mind is connected to her." The Doctor explained and pulled his Sonic Screwdriver. The machine buzzed and Twilight disappeared in a flash of green light being replaced with a changeling. "I only needed a second to find her signal, now I can find her." he told the Princess.

The changeling noticed the terrified and hurt SPike and tried to approach him but he also step back. The pain in the changeling face was clearly visible but it was then replaced by a powerful pain all over its body.

"I´m sorry, your usefulness is over. But before you leave I have something to tell to your boss..." and the Doctor grabbed the changeling face and look straight at its eyes, pass its eyes, right into the eyes of the Changeling Queen. "I´m coming for her...and for you too."

And with that, the changeling turned into green dust and was wiped away by the wind in the wind coming from an open window.
