At the end of the episode, she relents and tells Rusty that he can help them on the condition that he see a therapist like she's been wanting him to do for months. He reluctantly agrees.

Sharon: Rusty, what you are is who I love, and all of you is coming home.
The moment in "Personal Day" when Sharon offers to go with Rusty to visit his mother in rehab to make things easier for him. He thanks her the offer and then says that he's put her through enough trouble over the last two years and he already doesn't know how he's going to pay her back.
Sharon: Rusty, I've told you a hundred times.
Rusty: I know, I know, graduate and go to college. But Sharon, there's got to be something in all this for you too.
Sharon: *smiles at him like he's the light of her life* There is.
In "Flight Risk", Sharon is going to make the death notification to the mother of two young children who were killed. She's known this for about a day, but held off because she believed the woman to be a suspect. And now she goes to tell her the bad news... except that Flynn tries to do it for her.
Flynn: Sharon, listen. You've been a good friend to me over the last year, what with my daughter's wedding and everything. You don't have to do this. Let me do it.
Sharon: She deserves to hear it from me, mother to mother.
Flynn: I understand. I'll wait for you. If you need me.
Sharon: *a soft, sad and grateful smile*
Rusty coming out to the Major Crimes team about being gay, and their acceptance of him. (Note that everyone knows Rusty is gay, they're just waiting for him to come out.) Provenza says it best:
Rusty: Would it bother any of you, w-would any of you think differently if I said I was gay?
Provenza: The answer is, if you told us you were gay, we would trust you more, and we would think that you trusted us more.
Although it weirds him out, Provenza assures Rusty that nothing has changed between them.

Every single member of the Major Crimes team, including Doctor Morales, is wearing funeral attire and going to the service.
Flynn: Listen, you guys don't need to come along. I'm only going because I hate the thought of locking her up in the burrito room without anyone being there to say goodbye.
Provenza: We all hate it, Flynn. That's why we're going.
And then, at the funeral, Raydor and Flynn are standing side by side. And then slowly, deliberately, Sharon steps closer to Andy and bumps shoulders. And he looks at her and they share a small, grateful smile.
At the end of "Two Options", Rusty agrees to let Sharon adopt him.
Rusty If I ever end up in a box like this, I'd like to know there's at least one person out there who'd go look for me.
Sharon: Oh, I would look for you. And I'd find you.
