Who Is Ramona’s Real Father in ‘Sterling Point’ Season 1?

‘Sterling Point‘ spent an entire season teasing one answer to its central paternity mystery, only to flip the script in its final stretch. The Amazon Prime drama, created by Megan Park, follows 17 year old Annie Jacobson as she discovers a secret half sister living on the island she just inherited, and the identity of that sister’s father becomes the emotional engine of the whole season.

For most of the run, viewers were led to believe one man was definitely Ramona’s biological dad. The truth turns out to be something almost nobody saw coming, and it reshapes the entire family tree by the time the credits roll.

Ramona’s Father Was Assumed to Be Joe for Most of the Season

Throughout the season, it’s heavily implied that Joe, played by Jeffrey Dean Morgan, who runs the boats on the island and is the dad of Ramona’s friend Ellis, is Ramona’s biological father. Joe and Ramona’s late mother Goldie had a complicated shared history, and the show leans into that connection for the bulk of its runtime.

Digging into the past, Annie learns that Ramona is the biological daughter of her adoptive mother Goldie, though the identity of Ramona’s father had otherwise been a mystery for her entire life. Ramona had been told growing up that her biological father was simply a tourist Goldie had a fling with, which left the door wide open for fan theories once Joe entered the picture.

The clues pile up fast once Annie starts connecting the dots. The discovery of a mixtape left behind by Goldie, along with legal papers from her grandfather Gordon, strongly suggests that Joe fathered Ramona, and Joe himself comes to believe he is Ramona’s biological father, going as far as wanting to be her guardian despite her own wishes.

The emotional stakes get even messier once Joe’s own family gets pulled in. Ellis’ parents actually separate when it looks like Joe might be Ramona’s birth father, which turns a private paternity question into a full blown crisis for a second household on the island.

The DNA Twist Changes Everything

Just when the show seems to have settled the question, ‘Sterling Point’ pulls off its biggest swing of the season. Episode 7 flips expectations when Ramona learns from Annie that Steven also has color blindness, the same condition she has. Since color blindness is genetic, that detail becomes the thread that unravels everything fans thought they knew.

Because the condition runs in families, Ramona asks Steven to take a paternity test, and the results confirm that Steven, not Joe, is actually her biological father, overturning everything the characters had believed up to that point. It’s a gut punch of a reveal, especially given how much emotional weight had already been placed on Joe’s presumed role.

The full picture becomes even sadder once Joe explains himself directly to Ramona. He admits he was ready to leave Ellis and his wife to build a life with Goldie and the baby, but Goldie died in childbirth, so Ramona’s grandfather Gordon took the baby in so Joe could return to his family and keep the affair quiet. That confession reframes Joe not as a man avoiding responsibility, but as someone who genuinely believed the truth for years.

The show’s creator has been candid about how these family reveals ripple outward. Speaking to Deadline, showrunner Megan Park noted that Ellis gets pulled into Annie and Ramona’s sisterhood puzzle once his father Joe is believed to be Ramona’s dad, and that the situation ends up testing Ellis in ways that push his own relationship with Annie forward.

How Steven Fits Into Ramona’s Family Tree

Steven’s connection to Ramona is what makes this twist land so hard, since he was never even part of the original suspect pool. By the finale, the family tree settles with Steven as Ramona’s biological father and the adoptive father of both Annie and Connor, while Joe is confirmed as the father of Annie’s love interest Ellis, the man who had believed for years that he fathered Ramona following an affair with her mother.

Steven’s road to this discovery was buried in his own denial for most of his life. Steven knew his estranged wife was pregnant while she was staying in Sterling Point, but he assumed the pregnancy was the result of an affair, since a major source of strife in their marriage had always been his inability to have biological children. That assumption meant he spent years believing Ramona had nothing to do with him at all.

There’s also a darker layer to how Goldie actually died, one that Annie herself had to unlearn. It was Joe who took Annie’s mother to the hospital the night she died, not from cancer as Annie had always been told, but in childbirth while delivering Ramona. Learning the real cause of her mother’s death becomes just as disorienting for Annie as the paternity reveal is for Ramona.

What the Ending Means for Annie and Ramona Going Forward

Once the DNA results are in, the sisters have to figure out what to actually do with that information, and the island itself becomes part of the equation. After agreeing not to sell Sterling Point because it held too many memories, Ramona and Annie land on a plan that lets them have the best of both worlds. Ramona chooses to go to New York to build a relationship with Steven, while Annie stays behind on Sterling Point, since that’s where she feels most free.

That split ending fits the tone the show has leaned into all season, prioritizing emotional honesty over a tidy bow. Talking to TV Guide, creator Park teased where things could go if the show returns, saying their story is only getting started once real life logistics like distance enter the picture.

Joe’s arc doesn’t get fully resolved either, and that ambiguity seems intentional. The finale’s quieter emotional beat comes when Annie seeks out Joe for closure, hoping he can offer some insight into the mother she never really knew, a scene that treats Joe as family even after the DNA test rules him out biologically.

Between the color blindness clue, the mixtape, and two entirely different men believing they were Ramona’s father at different points, ‘Sterling Point’ turned a simple paternity question into one of the most talked about twists of the summer. Now that Steven’s identity is confirmed and the sisters have gone their separate ways for now, what do you think Ramona’s relationship with Steven will look like if ‘Sterling Point’ comes back for a second season.
