...Billie is going to have an incredible inferirority complex regarding her siblings, isn't she?
Billie might just decide to work with Daddy to make sure she can do the one thing her siblings don't seem to have any interest in.
Actually working in the film industry
That's if Sarah isn't inspired to go into Dreamworks or Hanna-Barbera with her love of animation. Or if little George decides to copy his dad or follow in his namesake's footsteps. Plus decent chance we have a fifth Gosling before Billie.
But yeah, even being a great actress, it would be rough for Billie to be the youngest and have such gifted older siblings. Then again, she's got half of Bruce's genes here and some Irish luck, who knows what will happen.
It's also kind of funny that Joseph is a bit of a daddy's boy considering if he's a super athlete, he'll be the first choice to take over the Lakers and Geese.
Going to be weird for the Future generations when they realized that three of the most insane and greatest people in the 21st Century are related and siblings by being the Children of one the Greatest Actors in Hollywood. If this isn't considered a Golden Family Tree then I don't know what is.
Don't forget Cat is an accomplished children's author and screenwriter and Gavin came in clutch to push Apple into the dominant corporation it shall likely be. Plus we have what their children will go up to, O'Brian blood really has something.
Of Course Carrie is successful in her own right, Debbie is a great actress and Todd might do something. Eddie has no idea what he missed out on by not even trying to be a decent father.
While on topic, if Succession is made ITTL, I imagine that there might be some side characters who are a parody of the O'Brian family and are noted rivals to the Roys, with all of the Roy children being especially peeved on how the faux O'Brians are all super successful and managed to break out into lots of different fields while they are just nepo babies, and this further reinforcing Logan's disappointment and frustration with his children, another reason not to settle the Succession.
One episode, one of the Roys heads over to the faux O'Brians and is absolutely astonished that they're a loving and tight knit family who don't obsess about the family business and are pretty chill about who inherits it. They think it's because of the kids geniuses, but really a great deal of their success comes from having happy and healthy childhoods with strong support networks that just enhanced their talents. Thus it further reinforces themes of cycles of abuse and how rich families can be set up to fail by their coldness and obsession for wealth and power.
