Not much is known about this mysterious, power-hungry rat. The character from the books is completely different from the character in the film. But even though the guy's a self-absorbed megalomaniac who would kill to get power, some of us can't help liking him. Are we crazy? Perhaps. But having a thing for the villain is not uncommon. After all, without evil there can be no good, right? So maybe it's not so crazy.
So there! ;)
In the books, all sorts of info is given out about Jenner. But in the film, all we know is that he was once a great friend to Nicodemus, something happened, and then he wasn't. In the books, he has a mate, a son, and a daughter. However, the mate is never given a name, and neither is the daughter.
In the film, though, it is unknown whether he has a family or not. If he does, they aren't shown. I personally believe that he did. Now, sorry guys, but he HAD to. I don't think any straight guy could dress that well on his own.
But hey, I'm human. I could be wrong.
