To me baby Zan no matter how cute he was does not exist!
The storyline was so crazy you have a whole season looking for the kid only to find out he is all human so they give him up for adoption no.
There could of been a way better storyline for that plot. Kivar was a let down to me as well.
A lot of season 3 I didn't like but that is just me.
remember I wrote a fan fic called The Journey Home where I tied to tie up lose ends from season 2 and 3. I even had it where it was Jennifer and Larry (from the pilot) were the ones who ended up adopting baby Zan.
