Can someone, for the love of all that is holy...

You should remember that William's inability to understand Danish is something important in the movie. Just like him, we were left wondering what the discussion was all about. By having no subtitles, the director tried to make the viewer become closer to William' story.

This is just the translated Danish, in order as it appears.

Scene in the great uncle's house:
I loved your father.
You look like him.
This letter is not for me.
I am your father's uncle.
Go get the pictures. I have pictures. Hurry.
He disappeared. Your grandfather was a terrible man.
He was a Nazi, a Danish Nazi.
By 1944, he was just as bad as any German soldier.
He said: "What the *beep* are you saying?"
Watch your mouth or I'll feed you to the dogs!
I borrowed a camera and took those photos of your father myself.
We sent them to your grandfather in jail but they came back returned.
When the war ended, your grandfather was arrested with a sentence of execution...but it was quickly changed to life in prison.
Of course he was released after 6 years.
They shaved your grandmother's head...spit on her and beat her.
Your grandmother Marie came back after 6 years.
When your grandfather was to be released from prison.
She hoped that the three of them could start over in America together.
What Happened?
He was released from jail and they waited for him...but he just disappeared.
Nobody has seen him since.
So it was just the two that went to America.
You keep them. (the pictures)

Between Effy and the bartender in the nightclub:
Effy seriously?
Can I have two beers?
Henrik is here!
What?
Get out of here before he sees you.
Don't say anything, okay?
--------------------------------------------
The argument between Effy's mom and her boyfriend overheard by the protagonists when they snuck into Effy's room to get her passport(notice he says nothing about seeing Effy at the club or getting hit):

Are you okay?
No, I'm not okay.
What the hell are you doing?
I went to the bar for Ander's birthday.
I was going to have one drink and then...
First you tell me you can't come over.
Then you show up at four in the morning telling me you were at a bar.
Are you drunk?
Yeah.
Answer me, what's going on?
Please answer me.
Who else was there?
Were you with Heidi? Were you with Heidi?
I was alone, okay?
I was alone.
What happened to your face?
Stop it. Stop it.
I don't trust you.
--------------------------------------------------
Effy comes home to see her mom's boyfriend scraping paint off the walls:
Hey. I was starting to get nervous.
We should talk about what happened.
Hey. It's forgotten. It's forgotten.
Don't be afraid.
You know I would do anything for you.
If you want to go out, just ask me.
Don't talk to me like that. I'm telling mom.
--------------------------------------------------
Effy laying on her mom's lap talking to her:
How was the hotel?
It was cool.
It was nice of Morten to get you in there.
What about your birthday?
Have you thought about what we should do?
No.
I remember when you were little you loved to go to Tivoli.
The horse game.
You loved to play the horse race.
I remember that game.
You are probably getting too old for a birthday at Tivoli?
No. Tivoli is nice.

Teacher speaking to the class at the end:
You've been away for a week and I'm dying to hear...how was your praktik?
Does someone want to share their experience?
I worked in a chocolate factory in Osterport. The best part was the free chocolate. But it got a little boring by the end.
Is that right?
