Witcher Who are these chracters?

In these two screenshots are characters that I do not remember encountering in the game, and I did finish it.

This looks like it's from the first area of Chapter 1, but I don't remember the character's nor the situation.

One of the character's from the above gathering.

Who are these characters?

One of the characters, the one in both shots, is Berengar the other Witcher, who has a game-long quest about what he's up to. I agree, I didn't experience either of these sequences in the actual released game--maybe from a pre-release version--or perhaps the result of following a different path(I was neutral)?
