None of the other companions are this animated, they generally just stand there. Emmrich on the other hand (Lich or breathing it's the same) They put some effort into giving him this animated trait.
I always thinks its interesting to look at him, It's like he can hear things, and whateven he is hearing he is none too pleased about it. I was thinking spirits, but then why does he always looks so displeased? Wouldnt he look happy at times if that was the case?
Judging by his concept art it looked like they had something else planned for him at one point. I wonder if these animations could be left over from early development? They liked it so much they just left it in?
