Legalities: BTTF is Bobs'. Lisa and Aislin are mine. I sort of mixed an idea from two book series: The Unicorns of Balinor and The Unicorn Chronicles, but it's a minor thing. I'll give the ideas back. Promise.

Lisa awoke, her head and hearts pounding, the sound of the bullets and the cry still echoing in her mind. Doc? she thought, still very groggy. Doc? Doc! Doc!

"Doc!" she cried, sitting upright and finding herself lying on the soft grass in the small meadow, just a few yards from her house. Breathing hard, she looked around, and realized she was no longer in the mall parking lot.

Her hearts gave an odd, painful twist, tears welling up in her eyes. She knew Doc had survived that attack…the second time. The first time…the first time, he had…

Lisa's mind reeled, feeling as if it would shut down from the overflow of emotion. She tried to calm down, but it was difficult. The image of Doc's motionless body was and had been firmly burned into her mind's eye.

I have to go, she thought. I have to go. "Right now," she said aloud. "I have to go. I have to find him. Now."

She picked herself up off the ground and dusted off her clothes, walking back to her house, contemplating exactly how she would pull this off. She had no idea where Doc was now. She could always go back to 1885, but there might be an easier way without involving her own time travel powers.

Lisa then remembered that the unicorns had a way of seeing where people were, no matter what planet or time. She knew they wouldn't mind her using it, but she needed a unicorn to do so. She had the means, for she could shape shift into a unicorn form, but she didn't like to use it and would rather not.

Then she saw something lying in a patch of grass several feet from her house. When she went to investigate, she saw it was Aislin.

Lisa knelt at the unicorn's side, stroking his soft neck. He was breathing slowly and deeply, as if he were asleep. "Aislin," she whispered. "Aislin?"

The stallion snorted softly and opened his eyes, nickering sleepily. He lifted his head and locked his bright blue eyes on Lisa, his ears shifting forward to full attention.

Like a bolt from the blue, Lisa finally understood. "It was you," she said. "You were the one giving me the dreams."

Aislin nodded, a humanoid gesture he had picked up, and said, "Yes, it was I. I could sense how much Dr. Brown wanted…NEEDED to see you. So I began influencing your dreams, inhibiting your ability to control them, and linking them when needed."

"I see," she said. "And this last one?"

"I felt time was running out, and you were…so stubborn. I felt you wouldn't believe it if I told you he missed you. Wanted to see you."

Lisa looked away. "Your right. I wouldn't've." She looked to him again. "But, it seems to me, you put your health at risk to give me the last one."

Aislin took a breath and heaved himself to his feet. "I'll be fine," he said, shaking dirt and dust out of his coat and prancing around a bit to prove he was fit. "Giving people dreams when they're awake takes a lot of energy. I've had ample time to recuperate." He faced her as best as he could. "Lisa, you MUST go back to Hill Valley."

Even with her previous urgency to get back to Earth and find her old friend, Lisa still hesitated. "Aislin, I don't know where or when he is. He could still be in the Old West for all I know."

Aislin smiled his unicorn smile. "I do. Follow me."

He led her to a small pool encased in sapphire-blue stones covered in glowing, moss-like yellow fuzz. Like all the water on Alnilam, the silvery liquid was so clear, one could see straight to the bottom.

This was the Waters of Watching, and it had the ability to show anyone or anything one desired, any place, any planet, any time. All that was needed was the natural magic contained in a living unicorn's horn.

Aislin stepped close to the pool and dipped his horn into the water. "I wish to see the present location of Dr. Emmett Brown."

The water rippled as the stallion removed his horn and continued to do so for a moment after. Lisa looked over the stones into the water and watched as an image appeared.

Doc Brown was in the same barn-turned-lab Lisa had seen in the dream she had lost her photo in. Aislin had told her on the way he had used some of his magic to allow the photograph to pass from the waking world to the dream world and back. It only worked if the object was held tightly; it could be lost between worlds, otherwise. Luckily, that didn't happen, and Aislin had accomplished his goal for that dream.

What hit her was how he looked: exactly the same. He still had the white hair, bushy white eyebrows, and the chocolate-brown eyes. He still wore the outlandish shirts and khakis. To Lisa, it's as if he hadn't changed at all.

Lisa saw Doc working on something the Waters blurred out, but the scientist was in clear focus. On the table beside him, she could see two photographs: the one that was taken in 1885 in front of the clock, and the one she took in 2015.

"He does have it!" she cried. "Aislin, you were right."

"Of course," he said. "Look here." He pointed with his horn to a wall calendar Doc had passed while walking through the lab.

She leaned closer to the water for a better look, squinting. "August 22, 1993…that's the same date my calendar says today is." Straightening, she looked at Aislin. "You mean he's there, in Hill Valley, in the present time? He came back?"

Aislin nodded. "And he's searching. For you."
