Did you say it? 'I love you. I don't ever want to live without you. You changed my life.' Did you say it? Make a plan. Set a goal. Work toward it, but every now and then, look around; Drink it in 'cause this is it. It might all be gone tomorrow."

When we say things like "people don't change" it drives scientist crazy because change is literally the only constant in all of science. Energy. Matter. It's always changing, morphing, merging, growing, dying. It's the way people try not to change that's unnatural. The way we cling to what things were instead of letting things be what they are. The way we cling to old memories instead of forming new ones. The way we insist on believing despite every scientific indication that anything in this lifetime is permanent. Change is constant. How we experience change that's up to us. It can feel like death or it can feel like a second chance at life. If we open our fingers, loosen our grips, go with it, it can feel like pure adrenaline. Like at any moment we can have another chance at life. Like at any moment, we can be born all over again.

There's a reason I said I'd be happy alone. It wasn't 'cause I thought I'd be happy alone. It was because I thought if I loved someone and then it fell apart, I might not make it. It's easier to be alone, because what if you learn that you need love and you don't have it? What if you like it and lean on it? What if you shape your life around it and then it falls apart? Can you even survive that kind of pain? Losing love is like organ damage. It's like dying. The only difference is death ends. This? It could go on forever.

Lexie: [narrating] Grief may be a thing we all have in common, but it looks different on everyone.
Mark: It isn't just death we have to grieve. It's life. It's loss. It's change.
Alex: And when we wonder why it has to suck so much sometimes, has to hurt so bad. The thing we gotta try to remember is that it can turn on a dime.
Izzie: That's how you stay alive. When it hurts so much you can't breathe, that's how you survive.
Derek: By remembering that one day, somehow, impossibly, you won't feel this way. It won't hurt this much.
Bailey: Grief comes in its own time for everyone, in its own way.
Owen: So the best we can do, the best anyone can do, is try for honesty.
Meredith: The really crappy thing, the very worst part of grief is that you can't control it.
Arizona: The best we can do is try to let ourselves feel it when it comes.
Callie: And let it go when we can.
Meredith: The very worst part is that the minute you think you're past it, it starts all over again.
Cristina: And always, every time, it takes your breath away.
Meredith: There are five stages of grief. They look different on all of us, but there are always five.
Alex: Denial.
Derek: Anger.
Bailey: Bargaining.
Lexie: Depression.
Richard: Acceptance.

MEREDITH: "You don't get to call me a whore. When I met you, I thought I had found the person that I was going to spend the rest of my life with. I was done! All the boys and all the bars and all the obvious daddy issues, who cares? I was done. You left me. You chose Addison. I'm all glued back together now. I make no apologies for how I chose to repair what you broke. You don't get to call me a whore."
DEREK: "This thing with us is finished. It's over."
MEREDITH: "Finally."
DEREK: "Yeah, it's done."
MEREDITH: "It is done."

[narrating] "At some point, you have to make a decision. Boundaries don't keep other people out, they fence you in. Life is messy, that's how we're made. So you can waste your life drawing lines or you can live your life crossing them. But there are some lines that are way too dangerous to cross. Here's what I know. If you're willing to throw caution to the wind and take a chance, the view from the other side... is spectacular."

[narrating] "The early bird catches the worm; a stitch in time saves nine. He who hesitates is lost. We can't pretend we haven't been told. We've all heard the proverbs, heard the philosophers, heard our grandparents warning us about wasted time, heard the damn poets urging us to ‘seize the day'. Still sometimes we have to see for ourselves. We have to make our own mistakes. We have to learn our own lessons. We have to sweep today's possibility under tomorrow's rug until we can't anymore, until we finally understand for ourselves like Benjamin Franklin meant. That knowing is better than wondering, that waking is better than sleeping. And that even the biggest failure, even the worst most intractable mistake beats the hell out of never trying."

Derek: I wanna be with you forever, and you wanna be with me forever. In order to do that we need to make vows. A commitment. A contract. Give me a piece of paper.
Meredith: I don't! I... I... I don't. I have post its!
Derek: (takes the post its and a pen) Ok. What do we wanna promise each other?
Meredith: That you'll love me... even when you hate me.
Derek: To love each other, even when we hate each other. (writes it down) No running. Ever! (Mer smiles and comes and sits in front of him) Nobody walks out. No matter what happens.
Meredith: No running.
Derek: (writes it down) What else?
Meredith: That we'll take care of each other, even when we're old, and smelly, and senile. And... if I get Alzheimer's and forget you...
Derek: I will remind you who I am, every day. To take care when old, senile, and smelly (writes it down) This is forever. (signs it) Sign.
Meredith: This is our wedding. A post it? (smiles)
Derek: Mhmmm. If you sign it.
Meredith: (signs it, and hands it back. Has tears in her eyes) Now what?
Derek: Now I kiss the bride. (They kiss)
Meredith: (smiling) Married.
Derek: (smiling) Married. (sticks their post it in Mer's locker) You see that? (Mer nods and smiles) Plenty of time.

We spend our whole lives worrying about the future, planning for the future, trying to predict the future, as if figuring it out will cushion the blow. But the future is always changing. The future is the home of our deepest fears and wildest hopes. But one thing is certain when it finally reveals itself. The future is never the way we imagined it.

You think that true love is the only thing that can crush your heart; that will take your life and light it up or destroy it. Then you become a mother.

It's just you. The one you can count on, and lean on, and depend on. It has to be you. And once you figure that out, that's when being alone becomes a choice.

Callie: Did anyone ever think you two were a couple?
Meredith: No, because we screw boys like whores on tequila.
Cristina: Then we either try to marry them or drown ourselves.
Callie: Huh.

Did you say it? 'I love you. I don't ever want to live without you. You changed my life.' Did you say it? Make a plan. Set a goal. Work toward it, but every now and then, look around; Drink it in 'cause this is it. It might all be gone tomorrow."

Meredith (closing voiceover)

I want to marry you. I want to have kids with you. I want to build us a house. I want to settle down and grow old with you. I want to die when I'm 110 years old, in your arms. I don't want 48 uninterrupted hours. I want a lifetime. Mmm. Do you see what happens? I say things like that and you fight the urge to run in the opposite direction. It's okay, I understand. I didn't, but now I do, I do. You're just getting started and I've been doing this for a long time now. Deep down, you're still an intern, and you're not ready.

Derek
