One of the most interesting theories inside the Margo’s Got Money Troubles fandom right now is the idea that Susie could become the “secret weapon” of the finale. After Episode 7 aired, fans suddenly started paying much closer attention to her character, and now a huge part of the audience believes she may end up being the person who saves Margo when everything falls apart.
The reason this theory exploded so quickly is because Susie has quietly witnessed almost everything happening inside the house. While other characters are constantly fighting, panicking, manipulating each other, or getting emotionally consumed by the chaos around Jinx, Susie has mostly stayed observant. She sees the tension. She understands how unstable things have become. And unlike some of the other family members, she doesn’t seem blinded by emotion whenever Jinx is involved.
That detail has become incredibly important to viewers.
A lot of fans now believe Susie understands Jinx better than anyone else in the family. She sees the side of him other people either ignore or excuse, and because of that, many viewers think she may eventually become one of the only people willing to tell the truth about what’s really been happening behind closed doors.
The custody case theories are where things get even bigger.
Across social media, fans are now predicting that Susie could testify for Margo in the finale. According to the theory, Susie’s testimony may become the thing that completely changes the outcome of the custody battle. Viewers think she has the perfect combination of qualities for that role: she was there for the major incidents, she personally witnessed the family dynamic, and most importantly, she comes across as calm and believable.

In a show filled with emotionally chaotic people, Susie feels grounded.
And ironically, that’s exactly why fans think her words could matter more than everyone else’s.
A lot of viewers have even started rewatching older episodes looking for clues that the writers planned this twist from the beginning. Scenes that originally felt small or unimportant are now being interpreted differently. Fans point to moments where Susie quietly watches arguments unfold without speaking, or scenes where she seems uncomfortable around Jinx but chooses not to confront him directly. People now think those moments may have been subtle setup for her eventually stepping forward when Margo has nobody left to defend her.
What’s especially fascinating is how unexpected Susie’s rise has been.
Earlier in the season, she was barely one of the fandom’s most discussed characters. Most online conversations focused on Margo’s emotional breakdowns, Jinx’s increasingly disturbing behavior, or the darker twists surrounding the family. Susie mostly existed in the background.

But Episode 7 completely changed audience perception.
After that episode, viewers suddenly started calling her “the smartest person in the house,” “the only sane one left,” and even “the hidden MVP of the season.” Some fans now believe the writers intentionally kept her quieter early on so her importance would hit harder near the ending.
The uncertainty surrounding the finale has only made these theories grow even stronger.
Because creator David E. Kelley has reportedly changed major parts of the original novel — especially by expanding the roles of characters like Jinx and Shyanne — even book readers no longer know exactly how the story will end. That has created a rare situation where both longtime readers and show-only viewers are theorizing together.
And right now, Susie is at the center of a huge amount of that speculation.

Some fans think she’ll expose Jinx in court. Others believe she’ll reveal information nobody else knew. A few theories even suggest she may have already been documenting certain incidents throughout the season without anyone realizing it.
Whether any of those predictions turn out to be true or not, one thing is clear: viewers no longer see Susie as just a side character. They now see her as someone who could completely alter the direction of the finale.
And honestly, that possibility is exactly why fandom discussion around her has become so intense over the past week.
