I would love to see Nere become a companion! From a RP perspective he could serve as conduit to glve the players a glimpse into drow society from a perspective of a man (as a mirror to our female drow companion). His banter with Minthara would have been hilarious too. I could see potential for an interesting rivalry mechanic going on between them. On a shallow note, I like his character model and outfit, he would have been a pretty addition to my drow Tav's camp.
The game clearly favours the good path, which is a shame because both routes are equally valid and the amount of content should be comparable.
