That's an excellent point. And this is where we find out that Halsin's family was murdered by goblins, while he was held as a sexslave by drow.
The guy clearly has plenty of issues that needs attention, and they dealt with none of it in any way whatsoever. Instead they just made him into a sex-joke. Weird choice to be honest when it could have been a great story with lots of depth.
Again, sort of feels like the last parts of him was thrown together in a rush without even attempting to tie together all the loose threads from ACT1-2.
