User blog comment:The Woolly Howl/He's not dead?/@comment-352641-20160628135733

They deep fried Alvin with lightning in the water and he escaped, though in that case he just swam away. Not so much of an option for Dagur. He's probably dead and gone, but it's ambigious enough he MIGHT come back in some form. I'm not hedging my bets on it, they went really out of their way to play the whole 'Dagur is redeemed' what with them deciding to retcon his original backstory about his father and such.
