Who lives in Merediths house   Ive had to edit this several times over the past few days and different individuals keep changing it back  In assuming good faith I will guess that these are individuals who have not yet been able to watch the full third season  However as of episode x Scars and Souvenirs which has aired in the United States and Canada Alex Karev is a resident of Meredith Greys home  George had moved out prior to episode x Walk on Water leaving his room vacant as he moved into the Archfield Hotel with his new wife Callie Torres  Alex moved in and took residence of the room that George once lived in  The rent paying housemates are Alex and Izzie not Izzie and George
