It's heartbreaking isn't it. You get a small snapshot into what his life was like growing up with a pushy, controlling parent like DA. He's lost an entire family, but perhaps in some way it's a relief. He was attached to this toxic family, obligated to spend time with them, communicate with them and deep down he knew he despised who they were, but refused to acknowledge those dark thoughts. So he maintained this superficial, "loving" relationship with his family members. He has lost something he never had, a loving family. But now he has his own family to love and support him.
