Where Carlos is not Cruella's biological son, when she heard that Auradon was going to trap Villians on an Island she decided to get one last payback and kidnapped Anita and Roger's son, hiding him in one of her coats.
For reasons, Auradon doctors have to draw blood and run tests and since they are all in the system the test gets some kind of hit for Anita/Roger, maybe they have a rare blood type but the doctor runs it again and calls them in to do a more thorough test.
But Carlos is Anita and Roger's long lost son and the fall out of that.
Bonus if Carlos really wants them to be his parents but Roger is wary of Jay being his boyfriend because he's Jafar's son, not because he's a boy and tries to push Carlos towards Auradon boys.
At least until Carlos gives him an ultamatum, he comes with Jay and Mal and Evie or not at all, they were his family first, after all.
For some reason I believe Carlos is really into video games and he’s always playing and very updated about game releases. I can see him playing basically any gender but sports, but I think his favorite franchises would be Halo and pokemon
Jay like it too, but he’s not as good as Carlos. He get bored easily and go do some physical activity right after. His favorite games are the sports one of course
Mal like to play rpg because she can use magic and create an evil character (but she always have a good time playing a game where she can beat Jay on it, she never plays with Carlos though cause she don’t like to lose). She definitely would love the last of us
Evie don’t really play. She get nervous everytime an npc is going towards her. She never knows what to do and always make the camera rotate crazily. After 5 min she gives up and pass the controller to Mal or Carlos. But she would really like cozy games like farming/building/simulation ones
Carlos: “What are you in the mood for?”
Jay: “World domination.”
Carlos: “That's a bit ambitious.”
Jay: “You are my world.”
Carlos: “Aww...”
Jay:

Jay:
Carlos: “OH.”
