As Twilight awoke, she noticed they were still in the spot they were yesterday. They must have fallen asleep there.
But Ace was awake before her. "Morning." He said.
But Twilight was always up extremely early. How could that be?
"How did you get up before me?" She asked.
"I don't need much sleep." He stated.
Spike looked at her again.
"Who are you talking to?" He asked, confused.
"Ace!" She answered, surprised by this question.
"There's nopony there..." He said.
"Of course there is!" She exclaimed.
"Okay..." He replied, saying the same thing for the third time, before walking away.
Spike figured that it was some sort of experiment Twilight was doing.
"Twilight, I have something to tell you..." Ace said, with a look of hopelessness in his eyes.
"W-what is it?" She stuttered.
"The reason why nopony notices me... Is because... Because they can't see me."
"Wh-why's that?" She asked, dumbfounded.
Ace became slightly transparent.
"Be-... Because I'm dead..." He almost whispered.
"I killed myself at the square... A long time ago..."
"B-but that can't be!" She said, tears streaming down her face.
"It's true... I only remembered now because you reminded me of what it was like to have somepony talk to me. To be alive."
He became more transparent.
"I have something else I need to tell you..." He said a bit louder.
"I love you..." He said quietly.
He embraced her as they locked lips, kissing for a full minute that seemed to go by very fast as the sun rose, hugging her tightly as he disappeared further.
"Don't go yet..." She said, crying into his shoulder, wetting his mane with tears as he grew colder.
"I have to." He said, now almost completely invisible.
"B-but I need to know... Why? Why didn't you tell me sooner?" She pleadingly asked.
"I didn't want to break your heart. Things got out of h-hoof. I... I didn't know I'd d-disappear like... like this. I... I'm sorry." He apologized.
"One last thing before I go... Continue on for me... I'll miss you, Twilight Sparkle..." He said smiling, tears streaming down his face just before disappearing completely. His words hung in the air for a few seconds, though he was gone. Yet his memory lived on in Twilight...
She still remained in the position he left her in, weeping softly.
She could never forget who Ace Sparks had been. She never knew why he killed himself. She never knew for sure why he didn't tell her when they met.
She would wait for him, always in the back of her mind, the moments they shared together...
Nopony knew him but her. Nopony would know him but her.
He vanished, leaving her forever behind...
