Keep Breathing

6 years have passed since Cristina moved to Switzerland, where she had her own hospital, her own cardiology, her own life. Things went as planned and she had even won a Harper Avery. Her excellent career couldn't be any better and she was convinced, that accepting Burke's offer was the best decision she could have ever made.
Her perfect life was suddenly interrupted by an incoming phone call, which forced her to return to Grey Sloan Memorial Hospital for a consultation for some days. But the situation unexpectedly changed within seconds, which made it impossible for her to fly back to Switzerland. Normally this wouldn't have been an extremely difficult situation, but she had a secret, nobody could find out or she was going to suffer the consequences.....

(Alex, Arizona and Callie are still working at the hospital)
