Okay, so you watched the season 4 finale of This Is Us and found yourself thinking, “who is the doctor and his daughter, Sadie.”
The episode spent so much time and attention on the doctor’s backstory, before we even knew that he was Madison’s obstetrician, and introduced his daughter.

Some may say that there’s nothing to it, it was just a way to introduce a character, but avid watchers of This Is Us know that’s absolutely false.
There has to be some bigger meaning and connection that simply hasn’t been revealed yet. Plus, they wouldn’t give us so much insight into Sadie being a horse-whisperer unless it was relevant.
Check them some of favorite theories about who Dr. Mason might be below and let us know if you have any ideas:
Theory #1: It’s Dr. Katowsky’s Son/Grandchild/ Relative
It cannot be a coincidence that Dr. K was heavily featured in this episode talking about his own loss of a child, right?
There’s a huge probability that Madison’s OB-GYN, Dr. Mason, is Dr. K’s son aka the child that he and his wife had after the first miscarriage. *a fan pointed out that child was a daughter, but Dr. K had other children. Someone pointed out that those children would be older and that he once mentioned having grandchildren, so it’s possible Dr. Mason is related in some way.
The doc seemed to have a knack for giving some really great advice just like Dr. K. He told Madison not to write off Kevin before she even talked to him and told him about the pregnancy, which led to Kevin being “all in” with the twins. There may be proof of this Dr. K and Mason are related because in the very first scene he tells Sadie that her horse is “is just a lemon.” And we know Dr. K loved his lemon metaphor.
Theory #2: Someone Like Dr. K
Considering Dr. Mason gave great advice just like Dr. K, many fans believe he’s going to be a huge part of Kevin and Madison’s pregnancy journey. He might be the one that they turn to for advice, guidance, and assurance just like Kevin’s parents did with Dr. K after he delivered Kevin and Kate. It would be a sweet way of bringing things full-circle. And hey, this still allows the Dr. Mason to be Dr. K’s son. Dr. Mason might be Kevin and Madison’s person.

Theory #3: Dr. Mason is Kyle
Okay, this theory is kind of wild and if This Is Us was a thriller drama/ telenovela rather than an inspirational, heartwarming family drama, we might consider it to be true, but sadly, we don’t think it is. That being said, we’re including it because it’s fun to imagine “what if.”
What if Dr. K was so desperate for a son that he stole one of Rebecca and Jack’s children instead. Imagine if Kyle never died but was taken and raised to be Dr. Mason, who reunites with his biological family, the Pearsons, years later by sheer coincidence when Madison walks into his office pregnant with Kevin’s twins. Again, if This Is Us was that kind of show, which it isn’t, this would be an incredible plot twist.
However, Dr. Mason seems older than Kevin, Randall, and Kate, plus, I wouldn’t want anything to tarnish the sweet, innocent Dr. K, who is a gem in this world.
Theory 4: Sadie Needed to Give the Doc Advice
Maybe Sadie and Dr. Mason were only necessary so she could give her dad that he then gave Madison about Kevin: “Little early to give up on him, don’t you think? You haven’t even give him a chance to be himself yet.” Sadie is a horse and Kevin whisperer.
Theory #5: He’s Madison Future Husband
Madison knows she’s not Kevin’s great love story, and she’s fine with it. Maybe through all of this, she falls in love with the doc and Sadie becomes her step-daughter. There’s no confirmation that Madison becomes Kevin’s wife simply because she’s carrying his children, so it’s entirely possible they both move on while being connected by their twins.
Showrunner Dave Fogel told Deadline that Dr. Mason will 100% become instrumental next season: “The doctor becomes an important character next season to Kevin – he’s having twins with a virtual stranger, not a normal birth experience. It’s no coincidence he was introduced in the same episode that Dr. K returned.”
That has to confirm Theory #1, right?
