the hunt, the ending

Some say that it was all in his head
I don't buy it tho, and I don't think Vinterberg ever established that kind of narrative in the film
Its a very real and documentary feel like film, where subjective things like that never happen

Who? I don't know :[
Some say that it was the brother who supposedly was abusing Klara all along

I think Vinterberg left it open, as a reminder that in this kind of cases, we never really known it all, some things are always kept hidden, regretfully

I think the point is that it doesn't matter - that despite everything being superficially back to normal, the whole incident is still hanging over them and he's always going to be looking over his shoulder. So I wouldn't say "in his head", but I think it was more symbolic rather than literal.

I've always thought that it was the big, ogre looking guy that slaps up his son whenever his son tries to talk to Klara at her house. He just always seemed to have his mind made up about Lucas. In the end before the hunting ceremony you can see they shake hands but he is not too thrilled about it. But that's just my theory.

Like the above person said, I don't think it matters who took the shot. The implications of that shot is what's important.

I just assumed that it was someone who still doesn't believe Lucas' innocence.

For me it's hard to tell if it was a hallucination or if it was real. Nonetheless if it was real, the person could of easily killed him.

But his goal was just to scare Lucas.

Perhaps I'm just unimaginative, but I thought it was their way of highlighting the fact that these sorts of situations never truly end. I'm totally up for believing that it had a deeper symbolic meaning but I personally thought it was the viewers chance to share a very harsh realization with Lucas.

My interpretation was that the shot was obviously real, but that silhouette kind of represented anyone who thought he did.

With such a serious accusation, ones life would be forever changed and there will always be doubts of your character.

Hi,
I feel it is Torsten, Clara's brother.
In one of the scenes, just before the snowfall, Torsten shows empathy towards Clara while they were preparing for Xmas.
