Katherine Heigl & T.R. Knight Say GoodBye On Grey’s Anatomy Season Finale!?! (Spoilers)

WARNING: SPOILERS. It’s a busy day in Seattle Grace. Meredith (Ellen Pompeo) takes a home pregnancy test and finds out she is pregnant with Derek’s (Patrick Dempsey) baby. The two agree to go out to dinner later and Meredith plans to tell them the news then.

Mr. Clark, who was the husband of one of Derek’s patients, wants revenge for his wife’s death as he blames Derek and Lexie (Chyler Leigh) for pulling the plug. The desperate man is looking for Derek’s office when he finds Reed (Nora Zehetner), who tells him to go find a nurse. He shoots her point blank, between the eyes. She dies! Alex (Justin Chambers) turns the corner, surprises Mr. Clark and he shot our dear Alex in his right side.

April (Sarah Drew) sees Reed’s body and warns Derek there is a shooter in the hospital. Alex managed to crawl to the elevator and go to the main floor where Mark (Eric Dane) and Lexie find him and help him. Alex is going to survive, despite his short hallucinations with Izzie (Katherine Heigl). Meanwhile, the police, helicopters and SWAT team have arrived and the hospital is on lockdown.

Christina (Sandra Oh) and Meredith assume a psychiatric patient got out and they try to find Derek. They found him and he promptly shoves the two women into a supply closet and orders them to stay there. Mr. Clark finally finds Derek, pointing a gun at him and saying he will be a man and stand up for his wife now.

Derek tries to talk to him but when April bursts through the door Mr. Clark shoots Derek in the chest. April tries to help Derek. SWAT team comes in and the shooter runs away. Meredith comes out of the closet after a fight with Christina and the two along with April take Derek to the OR immediately.

Christina is forced to operate on Derek, who has a bullet lodged right by the aorta, to save his life. In the middle of the surgery, Mr. Clark comes in and threatens Christina, pointing a gun at her. Meredith tried to play hero and says he should kill her since he is Derek’s wife and Lexie’s sister. He agrees and points the gun at her. Christina screams Meredith is pregnant and Owen is shot.

They pull the monitors off to make Mr. Clark believe Derek is dead while Meredith cries uncontrollably. He leaves and they keep working on salving Derek’s life. Meredith attends Owen, who was shot in the shoulder, but she is in a lot of pain. She is having a miscarriage. Derek will make a full recovery. SHOCKING!

And the rest is history… you have to watch this episode. There are a lot of details and a lot of things happening. It was probably the best episode of Grey’s Anatomy.
