This is two years after the end of season three. Derek has just been named Chief of Seattle Grace as Richard finally retired to be with Adele. Derek proposed for the third time at their celebration dinner and Meredith finally said yes. They had moved in together in an apartment as their house was being built on Derek▓s land. Izzie and Alex were still in Meredith▓s house. Christina had her own apartment and had finally started dating a year after Burke had disappeared. Then would randomly find out he was in such a such a country but she didn▓t care. She got to date on her own rules. (One small change, George did pass his intern exam.) Izzie and Alex started dating about a year ago and were going strong and in love. Addison had left to L.A. and Mark went back to New York. Bailey had become Chief Resident. Lexie and Meredith set aside their differences and became semi-good friends. And George? Well you▓ll just have to continue on to find out what happened to George.
