Andrea and Gabriel raised their son in their family ranch, taking care of animals. Carlos came out to them when he was seventeen. They were shocked but still hugged him, told him they loved him and that's it. The next morning, they talked about the Astros bullpen, the new calf in their ranch but not about his coming out.
Learning about Carlos and TK's relationship
In "Friends With Benefits", she meets Carlos and TK when her and Gabriel are at the farmer market. They say hello to each other and Carlos introduces TK to them as his friend. They talk for a bit and Andrea leaves, accidentally calling TK "TJ".
Later, in "Bad Call", we learn that Gabriel and Andrea knew Carlos and TK were dating when they saw them at the farmer market.
In "Slow Burn", Andrea and Gabriel comes by to Carlos and TK's place for dinner along with Owen. Andrea hugs TK when she sees him and waves TK's apology about running behind. She tells him that they're here early because Gabriel insisted on leaving early. Andrea apologises to TK about calling him "TJ" at the farmer market and TK tells her that it was nothing and that it's an easy mistake. Gabriel tells him that it's a mistake Carlos should've corrected and TK tells him that they had a talk about it. Carlos offers them drink and Andrea asks for a margarita before following TK to their seats, Carlos realises that he forgot the limes and TK is quick to reassures him by calling Owen so he can pick some. When he tells them the problem is solved, Carlos winks at him and Andrea and Gabriel are smiling at him. In "The Big Heat", Owen finally arrives two hours late, telling them that everywhere was stuck and that he couldn't find limes anywhere. He says hello to Andrea by kissing her cheek when she tells him that "they kiss in this family" and then he shakes Gabriel's hand. Once they're sitting, Owen tells Andrea and Gabriel that they have raised a wonderful son and Gabriel replies that they're very proud of him. Andrea tells him that TK is just as wonderful and that her and Gabriel couldn't be happier about TK and Carlos being together.
In "Push", Carlos is in TK's hospital room, staring at him before being interrupted by a knock on the door. He turns his head and sees Andrea at the door. They hug and Carlos asks her what she is doing here because he told her to not go out in that storm. Andrea asks him if he really thinks a few snowflakes will stop her from going to see her son who is hurting. Carlos asks her if Gabriel knows she's here and Andrea asks him what could Gabriel possibly say. Carlos says that he appreciates her being here and Andrea kisses his cheek. They both sat at TK's bedside and Andrea asks Carlos what did the doctor said. Carlos replies that they said TK is heading in the wrong direction, Andrea tells him that the doctor doesn't know everything and that TK is a fighter and that he has something to fight for; the love of his life who's sitting right here and waiting for him. Carlos confesses to his mother that he and TK broke up a few months ago. Andrea asks him why he didn't say anything, Carlos said that he wanted to but it was amazing how her and Gabriel were so supportive of them and he didn't want to let them down. Andrea replies that there is nothing Carlos could do that would let them down and that her and Gabriel are so proud of the man he is. Carlos thanks her and Andrea tells him that they love TK too but than when he wakes up, she's going to have a little conversation with him. Carlos asks her a conversation about what and Andrea tells him about how why TK thought he could break Carlos' heart and get away with it, making Carlos laugh when she added "Mama's not happy.".
While they're still at his bedside, it looks like TK is trying to wake up. Andrea pointing out that it looks like TK is trying to tell them something but Carlos tells her that the nurse said it's just muscle spasms, that they don't mean anything but Andrea isn't convinced. She tells Carlos that he has to talk to TK, Carlos refuses and when Andrea asks why Carlos responds that he wouldn't know what to say. Andrea tells him that he should tell him what's on his heart and Carlos replies that if he told him what was on his heart, it wouldn't be very nice, because he's angry. Andrea says that he should tell him anyway, because TK needs to hear it and Carlos needs to say it. Especially if this might be his last chance to say something to TK. She tells him that she'll be outside, kisses Carlos' cheek and leaves the room.
When TK wakes up and Carlos is pushed out of the room, Andrea joins him, comforting him as they watch the nurses and doctor check on TK.
Andrea and Carlos seemed to have a close relationship. She hugged him when he came out and told him she loved him and even though, they didn't mention it after that until they met TK, Andrea is very supportive of Carlos' relationship with TK. In "Push", when Carlos tells her that he and TK broke up, she's surprised and asks him why he hasn't said anything, he tells her that her and Gabriel were so supportive of their relationship, he didn't want to let them down, Andrea reassures him by saying that there's nothing he could do that would let them down and that they're very proud of him.
