Do you remember when we first met?
I remember this being the night where I went from being excruciatingly uncomfortable in your presence to...
perfectly at ease
I do.
Can we start over? Back to where we began?
Fitz. 
Simmons. I'm engineering, she's biochem.
You were so quiet and pasty.
I always thought Simmons and I would get on.
Sixteen and achingly shy?
So incredibly smart... handsome.
Spent months trying to think of something smart enough for her to notice me.
Two people, endlessly inquisitive, about to embark on a relationship that will change their lives but they don't know where it will go.
Quite a strange feeling, isn't it?
He's here.
I can feel him.
I knew from the moment I saw you, from our first conversation about dielectric polarization that...
I won't give up. I can't give up.
Never wanting to be without someone?
You'd be in my life for a long time.
I lost you once.
I can't lose you again.
What are you so afraid of?
He's losing himself
I know you've been hearing him
I feel like I'm losing him, too.
But I didn't know...
You would be my life. My heart. My home.
The universe can't stop us.
We just want to bring him home.
I'm just...
Not strong enough to live in a world that doesn't have you in it.
And you and I...
We're unstoppable together.
We're gonna fix this. Together.
And I will never stop fighting.
I still... miss her.
Please, not this memory.
What happens when we don't finish the job?
It was a loop of the end of the world.
Then we trust that someone else will carry on after us.
And you died to help break it. You died a hero.
Why would you make me do this? You're my best friend in the world!
I'll always be with you, Fitz.
Yeah, and you're more than that, Jemma.
It's quite lovely when you think about it like that.
Wrongs have been committed. Now we make them right. Together.
I don't know what I would do.
I was as clear-headed then as I've ever been.
Had I... Had I made that proposal to you before?
And there's only room in your heart...
For her.
You have to fix this.
I've got something magnificent right here.
I don't know how, Fitz.
You dove through a hole in the universe for me!
All my damage comes from you!
Well, all my pain comes from you.
So I'm asking you, heart in hand...
Jemma Simmons, will you marry me?
And then I think about the hell that you went through and the pain of not being there.
Come back to me.
Right now, here with you, I don't give a damn if we ever escape.
I'm sorry I can't give you back the time you missed. But I can give you me.
Now and forever.
