Visitation

Kailyn was the quiet one. The one that nobody noticed. The one that was largely ignored unless she threw her weight around. Perhaps it was the stigma of being adopted or maybe something that just warned people away.

It wasn't her attitude. She was easy to talk to and could keep secrets with the constancy of the universe. She wasn't bullied and she wasn't a troublemaker. She went to a good school, studied hard and she loved reading.

It was an ordinary Friday afternoon in September when her life started to change.

The service bus that she was taking between school and home was uncharacteristically deserted. Other than the driver, there were two old ladies on the lower level and Kailyn was alone on the upper level. She hadn't really noticed, as she'd been absorbed in yet another book. As they approached her stop, Clapham Junction, she put it away and stood to leave. As she did so, she heard a small noise, like the excess noise you get from headphones on full blast – tinny and electrical.

She turned back to see where the sound was coming from, maybe, she thought, someone had left an mp3 behind. But there was no mp3, nor any headphones to be playing it. Instead, a small ball of golden light, no bigger than her fist was floating in the aisle. It looked like dust in sunlight, but the sky outside was decidedly overcast. Intrigued, she reached out to wave her hand through it.

As she touched it, the sound magnified, there was a flash of light and Kailyn was floating in an ether of the gold. Disorientated, she started to flail and kick, but was held back by tendrils of the same light that seemed to wrap around her wrists and ankles.

"Greetings, my child" a singing, silvery voice spoke quietly in her ear. "I apologise for the restraints, but you came very close to disrupting the timelines, and that would never do."

Kailyn turned her head to see the person who had spoken, but there was only the light around her. Gathering her calm, she spoke.

"Who are you? Where am I and Why?" the three questions tumbled out.

"Everything and nothing, everywhere and nowhere, and I am not permitted to completely say, respectively." The voice was calm, smooth, and oddly reassuring, and Kailyn felt herself subconsciously relax.

"What can you say?"

"Very little, but I can show you."

A mirror seemed to coalesce from the light in front of her and after a second of her own reflection, Kailyn was looking at a domed room that appeared to be made from coral. A dark haired man was sitting on the floor with his back towards her, holding something up to the light. As the image zoomed in, she could see the object more clearly: a locket engraved with a rose. The man turned it over, read the inscription and burst into tears.

"Why does it always happen to me?" he choked, pocketing the locket and wandering out.

"This has not yet come to pass" said the voice "but it will in time, and Time has chosen you as the one who can save him from himself and thus repay the debt he is owed for saving us. That is the first thing I can say. The other is that your mother hid something with me, for when you were older, and that time is now."

The light where the mirror had been was coalescing again. This time, into a small silver pocket watch engraved with circles. "Take it and open it. Then I can take you home."

Trusting in the voice, Kailyn took the watch and held it for a second. Surely she was crazy, this didn't happen. Maybe that fish at lunch had been off and she was delirious.

Nevertheless, she pressed the button at the top of the watch.

"Yes!" the voice cried as the choir sang out again and Kailyn's world began the swim out of focus. "We shall meet again before your 20th birthday, my lady, and so too with your destiny…"

And she was back on the bus again.

Exactly where she had been before, arm outstretched, approaching her stop. The sound and the light had gone. Blinking, she took a deep breath and stopped. Could her heart beat that fast? She held her hand on her heart; normal. Feeling a twinge, she shifted her hand over; surely not another! She checked both simultaneously. Two hearts.

And on the seat beside her was the pocket watch.
