Dexter, Season 8

Dexter:
I can't believe she actually confessed. I thought I got her to see that she's a good person.

Dr. Vogel:
This could have been the only way she could relieve herself of the guilt.

Dexter:
Need you to help get her out of this. Give your expert opinion that she's having a breakdown.

Dr. Vogel:
Are you sure? This could be the best thing for her.

Dexter:
Spending the rest of her life in prison? That's the last thing Deb needs.

Dr. Vogel:
Or the last thing you need. If Debra goes away, odds are, you'll join her. Admit it, Dexter. You're mostly worried about yourself.

Dexter:
That's not true. I told you, I love her.

Dr. Vogel:
Not the same way she loves you. When Debra killed LaGuerta, it was real, selfless love. She sacrificed everything she believed in for you. Can you see that?
