AN: So new story. Couldn't sleep and decided to test out the idea. Lemme know how it feels, enjoy. As you all know All greys anything belongs to shonda. This story is mine with some borrowing from Shonda's brilliant writing.

Chapter 1

Callie Torres sat atop the apartment building adjacent to the newly christened Grey-Sloan Memorial Hospital. She could hear the combined laughter of Doctors Derek Shephard, Owen Hunt and Richard Webber floating off the roof as they shot golf balls off into the distance. She would begin work there tomorrow finally after having requested a transfer from Miami General two months ago. Hunt seemed surprised that she was willing to give up her very specialized ortho department to head up the new one here but he didn't question it. He would be stupid to after what she did with Miami department. It was cutting edge in every way and she had managed to make a name for herself with her cartilage research and impressive experimental bone reconstruction techniques. She also had one of the lowest patient mortality rates in the country. Her patients just seemed to not die on her, despite the number of radical and experimental new surgeries she was implementing.

Callie chuckled as she contemplated her old nickname from Miami general. Doctor Halo. It was a running joke that she had angels on her side keeping her patients alive for her. If only her colleagues knew how creepily accurate they were in giving her that nickname. Callie had been an angel living on earth for the past 150 years. She had been a nurse in the Civil War and promptly died in one of the ensuing battles. She was given a choice, she could return to earth as an angel to help or she could pass on and enjoy her afterlife. She had absolutely no idea why she chose to come back but she did and she had been here ever since.

When she first woke up after coming back down to earth she was butt naked in a forest and had a Halo glowing brightly above her head and some very feathery appendages sticking out of her back. She quickly discovered being an angel did nothing to get rid of the panic engulfing her. Yep, she felt human emotions just fine as far as she could tell. Years passed and she learned to tame and control her powers. She discovered she could "dim" the glow on her halo down to a light frequency that humans couldn't see but it always did amuse Callie when her cat started pawing at the air where her halo sat above her head. Her wings she could cause the appear and disappear whenever she actually needed them and they thankfully left her clothing intact once she made them disappear. Her first year as an angel taught her it was impossible to put clothes on when your wings simply could not fit through a small hole in the back of a shirt. As for her other powers, they were all more subtle. She did have the cliché angel ability of healing but it was mostly minor things. She couldn't cure cancer, but she could ease a common cold or stop a flu virus from killing someone outright. Her enhanced vision, remarkable strength, control and precision made her almost quite literally the perfect surgeon. Add that to the fact that she could sense the strength of human souls as well as see them once they left a person's body (aka dying) and you've got the perfect recipe for a rockstar in the OR.

Callie frowned as she watched the surgeons hit ball after ball into oblivion. For the first time in years she didn't feel like a badass ortho angel rockstar. She was nervous. After months of some creepy angel stalking on her part, she would finaalllyyy get to formally meet and work with HER. The girl with the gorgeous blonde curls and eyes bluer than any blue she had ever seen.

Callie sighed and spread her wings as she stretched from sitting on the cold concrete of the roof for so long. She took off into the night, her hair whipping around her face as she smiled and felt the wind rushing through her wings. A warm giddiness took over her as she flew around the city before heading back towards her apartment. A warm bed, a glass of wine, sleep and thoughts of Doctor Arizona Robbins would keep her company tonight.
