So whenever I do i notice something kind of funny with the quest and it should probably be changed. But the farmer refers to the corrupted as his "stepfather" the issue is after you deal with it he mentions his wife as if it's her father. And I get the idea but the issue is. Step family is not something you marry. It would be in laws.
A stepfather is someone who marries your parent. Not them being the dad of your husband, it should probably be changed because it causes a slightly weird issue that should probably not be discussed.
