Can't say I blame them really. After adopting two kids myself and having them always running up to me and initiating dialog every single time I come back to my house, I'm about ready to abandon them myself to the house in Riften I don't use. Maybe Constance will find out about them and take them in. I kinda sympathize with Grelod now and feel bad for taking her out.
He's a farmer in Rorikstead who regularly beats his twin daughters. Their mother died during childbirth and he blames them for her death.
I see. Well, I'm off for my shrouded armor. I have a certain man to vsit.
By the way there is no quest with him,right?
I think you can sell him vegetables like with most farmers but that's it. No real quest associated with him.
And once you kill him his daughters Sissel and Britt will be sent to Honorhall. After you complete Innocence Lost and you have Hearthfire installed you can adopt them. Most like to adopt just Sissel because Britt likes to beat up her twin sister too.
