Ansel wasn't actually living independently - he was living with Grey. But he has been moving towards more independence and Dex seems to finally support that. He is learning to drive, he is going on a date. He is achieving the goals he set for himself. And no one says that he has to move back in with Dex permanently. She is going through a particularly rough time and I think it is fine for Ansel to move back in to support Dex the way she has supported him in the past. While I think Dex will always be a little bit of a train wreck, she has been pulling things together lately and this last case has thrown her for a loop by bringing up all the Bennie stuff. I think admitting what really happened to Sue Lyn was good step toward moving past the guilt and grief she feels. If she can deal with Bennie, she will be in a much better place. And if Ansel wants to move out again at some time in the future, I choose to believe she would support that.
