Headcanon 25

Although Carrie calls Tony by his name most of the time, there are also a few times where Carrie accidentally calls him "dad".

One time, he surprised her with not only a concert to one of her favorite singers but he even paid to have a backstage meet and greet with her. Carrie was so happy that he did that for her that she said him, "Thank you so much for this! You are the best, dad!".

Not gonna lie, that caught Tony off guard just as much as it did her because it was so unexpected but honestly, warmed his heart to know that he earned that title from her even though he feels sometimes he isn't the best father and aren't related by blood.

Carrie got embarrassed the first time she accidentally called him "dad" but he reassured her that it was okay and that he actually doesn't mind or won't be bothered if she ever chose to one day permanently refer to him to that title.
