I understand Alaric. He's slept around so much that for him it's no longer about physical contact, but emotional connection. He's constantly on the go, and all the women just want to sleep with him, like he's some disposable rag. He needs to set things straight and make it clear that he's not just a sex object, but something more: a friend, someone they can trust, and someone who will always be there for them. And he needs to tell them all the truth and let them decide whether or not to be a part of his life.
Meanwhile, Nat needs to understand that her desires aren't the only thing that matters, but also the other people around her. She and Susan need to sit down and talk about how to navigate their lives with Alaric and the other women.
