It's now 7 pm and there's no food in the fridge so Christina and Tris drive to the diner down the street. They get to the diner and sit at the booth in the corner. They scan the menu and the waitress comes after a few minutes.

"Hey guys. What's your orders?" the blonde waitress asks.

"Hey Marlene. We'll get two cheeseburgers, one vanilla milkshake, one chocolate," Christina says.

"Okay," Marlene says than leaves.

Marlene works as a waitress but really wants to be a nurse. She dropped out of college as a sophomore because of the lack of money. She returns with their order and sits down beside Tris. She knows something's up.

"What's wrong Tris? You're so quiet, not smiling much and you ordered a chocolate milkshake. Which you only order when you have a problem," Marlene says.

Before Tris can answer, she hears a deep familiar voice. She looks up to the stage to see Four standing there.

I'm so glad you made time to see me
How's life, tell me how's your family
I haven't seen them in a while
You've been good, busier then ever
We small talk, work and the weather
Your guard is up and I know why

'Cause the last time you saw me
Is still burned in the back of your mind
You gave me roses and I left them there to die

So this is me swallowing my pride,
Standing in front of you saying I'm sorry for that night
And I'd go back to December all the time
It turns out freedom ain't nothing but missing you
Wishing I'd realized what I had when you were mine
I'd go back to December, turn around and make it all right
I'd go back to December all the time

These days I haven't been sleeping
Staying up playing back myself leaving
When your birthday passed and I didn't call
And I think about summer, all the beautiful times
I watched you laughing from the passenger side and,
Realized I loved you in the fall
And then the cold came, the dark days when fear crept into my mind
You gave me all your love and all I gave you was goodbye

So this is me swallowing my pride,
Standing in front of you saying I'm sorry for that night
And I'd go back to December all the time
It turns out freedom ain't nothing but missing you
Wishing I'd realized what I had when you were mine
I'd go back to December, turn around and change my own mind
I'd go back to December all the time

I miss your tan skin, your sweet smile, so good to me, so right
And how you held me in your arms that September night,
The first time you ever saw me cry
Maybe this is wishful thinking
Probably mindless dreaming
If we loved again I swear I'd love you right

I'd go back in time and change it but I can't
So if the chain is on your door, I understand

But this is me swallowing my pride,
Standing in front of you saying I'm sorry for that night
And I'd go back to December
It turns out freedom ain't nothing but missing you
Wishing I'd realized what I had when you were mine
I'd go back to December, turn around and make it alright
I'd go back to December, turn around and change my own mind
I'd go back to December all the time

All the time

Christina and Marlene are stunned, but not as much as Tris. Her tears were threatening to fall but she held them in. She would not cry in a public place, just because of a boy.

"I'm sorry Tris," Four says and leaves the stage and diner. And enters Tris' mind.
