Okayy so i thought of this idea the other day and decided to write about it, basically Cristina and Owen are happily together but then Burke comes back unexpectidly and mixes everything up, please review, this is only my second fanfic :D I will try and write the next chapter and upload as soon as possible :)

*******

Owen and Cristina are happily engaged and with Cristina pregnant everybody is getting to help out with the Cardio surgeries. It's been six years since Cristina and Owen had met each other and they couldn't be happier.

Owen was in surgery and Cristina was waiting to have a check up on the baby:

"Heyy, Cristina what are you doing here?" Asked Meredith

"I have another scan on this baby!" Replied Cristina

"Isn't Owen going with you?" Meredith wondered

"Erm I think so if he gets out of surgery in time, my appointment isn't for another half an hour yet but I wanted to come down and see everyone, I am just cooked up my house by myself." Answered Cristina

"Well then I shall sit with you for a while and catch up...."

They carried on talking until Owen came out of surgery and went with Cristina in to see her doctor. Meredith went to check on her patients and get them prepped for surgery.

Whilst Owen and Cristina were getting there baby checked a person from Cristina's past was making his way up to see the chief of surgery, Derek Shepherd. As he walked through the corridors everyone pointed and starred at him, wondering why he had returned to Seattle grace hospital.

He walked past one of Meredith's patients' rooms and Meredith was shocked to see him and thought she should warn Cristina so she made her way down to paediatrics.

Meredith found Cristina but she was with Owen:

"Cristina, I really need to talk to you, like now!?" Whispered Meredith

"What? Tell me Mer," Wondered Cristina

"I need to talk in private," Meredith hinted

"Hang on just ten minutes until my appointment has finished then I can talk," Cristina suggested

"Fine, okay I will wait outside," muttered Meredith

Meredith waited impatiently outside in the waiting room, ironically. She kept looking up to see if he was on his way out but he wasn't. The ten minutes seemed like hours to Meredith as she was trying to warn Cristina. Eventually Cristina and Owen appeared; Owen kissed Cristina and went off to check on his patients.

"What's so important that you interrupted my scan?" Asked Cristina

"Burke is back!" Replied Meredith

Cristina stood their speechless, hoping it wasn't true!
