Then again Fane sometimes bleeds.
Nope definitely undead. The bleeding is probably just an over site but the decent looking skin most likely comes from a mask of the shapeshifter like Windego had.
If you kill him use spirit vision and talk to his spirit. He'll tell you what's up and you see his true form. (that said for some reason you eating him is completely ignored in the ending so ugh.)
