The Doctor's POV

I opened my eyes and stared at the lightening sky. I was lying on ice and felt frozen to the bone. Confused, I tried to sit up and flopped. Pain shot through my body, white got and distracting.
Once the pain subsided, my head began to clear. I remembered what had happened with the Master and Gallifrey. New guilt crashed down upon me.
Then I absorbed a huge amount of radiation, shouldn't I be dead? I had said goodbye to everyone I cared about-except poor Eve who disappeared a few weeks ago. I still can't find her anywhere!-and stumbled my way out into the snow and seen Rose before she met me...
Then I saw her again and she was with Eve! I had collapsed... I don't really remember anything after seeing them bending over me.
I rolled my head to the side and saw Rose and Eve slumped in the snow beside me. Rose was only human! She could die from being out in the cold too long! That motivated me to get up.
Slowly, I propped myself up on my elbows and cautiously sat up. Spots danced in my vision and I pressed my hands to the snow-covered ground.
Once my sight cleared, I got to my knees, then my feet. I looked around and noticed the TARDIS a few yards away. Then, my superior Time Lord hearing picked up a sound: a double heartbeat. It wasn't my own, it beat a different rhythm. It was close. It wasn't Eve, I knew for a fact that she had only a single heart, despite her Time Lord DNA.
Dismissing my curiosity for Rose's sake, I picker her up bridal style, but then the sound got louder. Looking down at her, I scanned her with my sonic screwdriver, and stared in astonishment. She was a Time Lady! Oh, Rassilon, she had become a Time Lady. What happened?!
Questions filled my mind, while I rushed her to the TARDIS. I gently laid Rose on one of the Infirmary beds, and cupped her cheek. My Rose... But how was she here? On this Earth? Where was my Meta-Crisis version, John Smith?
There were frozen tear tracks on her face. What had made Rose cry? She almost never cried! She was so strong and brave, Rose Tyler, Defender of Earth!
After making sure that Rose was healthy, I began to pace. Questions buzzed in my brain. How was Rose a Time Lady? What had happened after I passed out? How was Rose here?
Something niggled at the back of my mind. Was I forgetting something? Then it hit me: Eve! I had left her our in the snow!
Slapping myself for my stupidity, I ran out of the TARDIS and found Eve exactly where I'd left her; sprawled in the snow. There was more blue in her hair, like she had highlights. What had she done that caused her to regenerate again? How was I involved? And Rose? I lifted Eve, who was surprisingly light. Her skin was cold to the touch, and she was limp as a rag doll.
Getting more and more worried about the companion who had saved me from depression by being a good friend, I deposited Eve on the bed she had earlier in the TARDIS Infirmary. I desperately wanted to know what had happened after she had disappeared, then returned.
Sighing, I resigned myself to wait.

Back to regular POV!

Eve drifted through a dream. She was being chased by a horde of angry monsters, a group including Hell Hounds, Weeping Angels, GenoMorphs, and so much more. Just as a Weeping Angel, fangs laid bare, was about to touch her, she jolted awake. Her body felt weak and drained, but not as bad as what she had felt after Darkseid's Omega Ray. Her muscles felt crampy and sore, her back hurt, and she felt a bit hypothermic, despite the many blankets wrapped around her.
Still half asleep and breathing heavily from the nightmare, she began to writhe beneath the blankets. She heard a familiar voice say to her, "Eve, it's okay, it's okay!" It was the Doctor. He was okay! She calmed and stopped thrashing.
She propped herself up on her pillows and pulled the blankets around her. She was in the Infirmary again.
"I keep ending up here, don't I?" She joked. The Doctor smiled. "Yeah, you do."
"It's very inefficient of me." She said. That made him laugh. Then he sobered, and asked "What happened, Eve? You disappeared weeks ago! Then you reappeared with Rose, who was on another earth, in another dimension, and is now a Time Lady!"
Eve sighed a little. "When we found you, you had held off regenerated so long that the regeneration energy was harming you instead of healing. The only way to save you was to remove it and I couldn't absorb it. Rose did instead. She really does love you, ya know. She'd do anything to save you."
Now it was The Doctor's turn to sigh. "And I, her. But, how is she here? She was with my Meta Crisis version."
Eve's face darkened. "When I disappeared, I found myself on the Earth where Rose was. I wondered why I had ended up there, until less than two minutes later, I heard a crash  and a scream. I found Rose and John, who had been hit by a car. Since he was half human-"
"He could die." The Doctor said, realization dawning on his face. "Oh, poor Rose."
"Yeah... his last request was that I took her back to you, so I did. Apparently, I can travel back and forth without causing damage."
"It probably has to do with your unique genetic code. You can travel safely through." The Doctor looked thoughtful. "So Rose absorbed my regeneration energy and it rewrote her DNA into a Time Lord?"
"I think so. I think she has fewer regenerations than most because she absorbed some of yours, so you should be about evenly matched." Eve said, her blessing from Apollo showing in her knowledge of the subject.
A smile began to play on The Doctor's lips. "So, she'll be fine!"
Eve laughed a little. "Yeah. I think that things will work out great." she probably wondered what would happen to the TV show back home. Had she created a parallel world like what happened to Donna? It was a thing to speculate about for another time.
"Thank you, Eve, for bringing her back. Also, im glad your back. I missed you!"
Eve smiled at him. She was about to go back to sleep when she heard Rose cough.
Eve struggled out of her mountain of blankets and to her feet. When she noticed she was wearing different clothes, ones she'd left on her room, a turquoise turtleneck and thick black jeans, she was horrified until the TARDIS hummed under her feet and she sighed in relief. Thanks, Beauty. Another hum, almost like a purr.
She walked over to join the Doctor at Rose's bed, stretching her burning muscles. Rose's eyes fluttered open and...

A/N: Here's another chapter! I hope u liked the Doctors pov.

This is just for the highlights. Eve has curly black hair, unlike in some of the photos. Which photo do you think is best? Please comment on the one you like best.
