Grey's Anatomy Universe Wiki
Advertisement

Disappearances happen in science. Disease can suddenly fade away, tumors go missing, and we open someone up to discover the cancer is gone. It's unexplained, It's rare, but it happens. We call it mis-diagnosis, say we never saw it in the first place, any explanation but the truth. That life is full of vanishing acts. If something that we didn’t know we had disappears, do we miss it?

Walk on Water is the fifteenth episode of the third season and the 51st overall episode of Grey's Anatomy.

Short Summary

A catastrophic mass casualty incident has the interns (sans Cristina) sent into the field with Bailey to do damage control. Back at the hospital, the Chief has dyed his hair and Addison is the only person who defends him. Cristina wants to tell Meredith about her engagement, and wants Meredith to hear it from her first - not easy when word begins to spread among the attendings.

Full Summary

Meredith is lying in a tub still and suddenly she's goes under. Derek comes in and wonders what she's doing. He calls her name and pulls her out of the tub and then leaves. Moments later, Meredith tells Derek and Izzie that she wasn't drowning or wanting to die.

At the hospital, Cristina tells Preston to wait until she tells her Meredith about their engagement. She wants to tell her friend and Preston says Derek is my friend. She says to not tell Derek because he will tell Meredith.

Everyone in the elevator including Addison is looking at Richard's head. Derek comes in the elevator and notice his hair color has changed. Addison tells them to leave him alone while the others are saying why the change.

At the newly clinic, Sydney comes down to help Miranda and her interns practice how to determine patients' injuries. Richard comes in and tells Miranda to put together a triage team because there has been a mass casaulity incident. Cristina stays at Seattle Grace Hospital to handle the incoming patients, while Miranda, Meredith, Izzie, George and Alex arrive and see multiple traumas from the ferry boat accident which caused the container ship clip the boat. The interns don't know where to start first, but Miranda tells them to just go help. Meredith finds a little girl afraid and crying. She won't let go Meredith's hand and so she takes her along.

Derek tells Preston of his love for ferry boats. Preston tells Derek he is his friend and Derek concurs. Preston then tell Derek he is engaged with Cristina and not to tell anyone, but Mark caught that and says congratulations.

Quotes

Callie: This is weird. Weird. This is weird, right?
Bailey: I need more triage tags...
Callie: Working with someone I’m married to is weird. Here, I’m his boss and his wife. At work, I’m giving him orders, in bed... He’s giving me...
Bailey: Stop! Right there, I don’t need to know this. I’m tired, I’m busy. While I will concede that you and O’Malley have some challenges to overcome, I’m asking you to remember that this day is a marathon and my mind can only hold what it needs to know, your sex life cannot be held in my mind today... Ever! It cannot be in my mind ever! Never!
Callie: Whatever.

Cristina: Meredith, I have a thing...news.
Meredith: You’re not pregnant again, are you? 'Cause I can’t handle the extra months of bitchiness.

Addison: (to Richard) I dyed my hair blonde... the day after Derek moved out. Change is good. Your marriage is over, you're starting over. So am I.

Richard: (to Mark) What's the news?
Mark: Shepherd and Grey are on the rocks. Burke and Yang got engaged. You need highlights in your hair. That's why it looks so odd. I'm gonna go save lives.

Alex: (to Jane Doe) Hey. I'm not going to be able to make it to your surgery today. (she reaches for his hand and grabs it) Here's the thing. You were crushed by a pylon. Dozens of people on that ferry boat died, but you're alive, so when I come back to check on you later, you better still be alive. Do you hear me?
