I think Sophie is a Disney channel actress and Chad has many roles from various places. So, they are probably teen acting friends that have grown up in the same circles.

Oops sorry, I corrected the title. Thanks for the two of you bringing that to my attention. lol
The thing about the son of Jack is he is supposed to be 7 years younger than RJ to where this actor tweeting is the same age ... so it's doubtful that Chad Roberts would be playing the role.
They would probably pick someone looking closer to the mother or father.
That's why I asked about Taylor having any unseen kids.
