If you don't kill owlbear you get approval point from Shadowheart and maybe get that sweet pie of hers. What I did was first I took that approval point from Shadowheart by letting owlbear live and then I killed that smelly owlbear. Then I get the choice to let owlbear cub live which I did and that gave me another Shadowheart approval point. Sweet Shadowheart pie, here I cum!!!
