I rather feel that the end game lacks some of the atmosphere of Acts 1 & 2.
By this I mean if you conquer the grove/wipe out the goblins you get a celebration.
When you beat the 1st of three you end up with a gathering of sorts.
In Act 3 killing the other two the response you get from your party feels no more demonstrative than finding out who's eating the pigeons, at the least you'd expect some camp based celebrations.
Finally - before you embark on the final battle I'd expect you and your partner would spend the night together as you both stand a good chance of not coming back.
