Gil’s relationship with Georgia in Ginny & Georgia was abusive, and his return brings that danger into the life she has tried to rebuild. As Austin’s father, Gil also has a connection to the family that Georgia cannot treat as an ordinary disagreement with an ex-partner.
Aaron Ashmore plays Gil. This guide focuses on the character’s actions and their consequences, including why the season-three ending requires a distinction between his abusive behaviour and a crime he did not commit.
Major spoilers follow for seasons two and three.
Why does Georgia fear Gil?
Georgia fears Gil because of his abuse during their relationship. Her reaction to his return is grounded in that history.
The tension is therefore different from the discomfort of a former partner meeting a new one. Gil represents a threat to the security Georgia has tried to create for herself and her children.
His connection to Austin makes the situation more difficult. Austin wants a relationship with his father without initially understanding everything that happened between his parents.
Georgia consequently faces two problems that cannot be neatly separated: protecting herself from Gil and deciding what her son should know about him.
The programme uses that gap in knowledge to create conflict. The children do not always understand Georgia’s decisions because they have not experienced the past that informs them.
How Austin’s letters bring Gil back
Ginny posts Austin’s letters to his father without knowing the danger associated with him.
From her perspective, she is helping her younger brother establish contact. From Georgia’s perspective, that contact reopens a connection she has reasons to fear.
Netflix’s explanation of the season-two ending includes Antonia Gentry’s account of Ginny not understanding who Gil was when she sent the letters.
The incident is revealing because it does not require Ginny to intend harm. She acts with incomplete information, and the consequences are far larger than she expects.
It also exposes the limits of Georgia’s secrecy. Keeping painful information from the children may spare them an explanation in the short term, but it leaves them unable to recognise a threat when they encounter it.
That is an interpretation of the family dynamic, rather than a claim that Georgia should have disclosed every detail. The story shows a difficult consequence of the distance between what she knows and what her children know.
Why Gil is more than an unwelcome ex
Gil’s importance comes from his ability to reach into the family through Austin.
An unpleasant former partner might be avoided. A parent seeking contact with a child is harder to keep at a distance, particularly when the child wants that contact.
That relationship gives Gil a place in Austin’s life even when Georgia wants him out of hers. It also creates room for competing accounts of the past.
For Austin, “my father” and “the person my mother fears” are not initially the same understanding. The storyline becomes more painful as those two identities begin to meet.
Georgia’s history with Gil therefore affects more than her own feelings. It shapes what Austin believes about his family and how he interprets the adults around him.
Why does Austin shoot Gil?
Austin shoots Gil in the arm while trying to protect Georgia during Gil’s attack on her. Gil survives.
The circumstances matter. Describing the event only as Austin shooting his father removes the immediate danger that prompts him to act.
The scene also marks a change in what Austin knows. Gil’s violence is no longer something Georgia has kept in the past or hidden from her children.
For Georgia, that is a devastating breach in the protection she has tried to provide. Her son has been drawn into the violence himself.
For Austin, it means acting during a crisis involving both parents. The emergency may end, but the relationships and knowledge remain.
There is no reason to read the scene as a simple transfer of loyalty from father to mother. Austin is a child responding to an attack, and his connection to Gil does not disappear because he intervenes.
What changes after Austin witnesses the abuse?
Austin now has direct experience of the danger Georgia associates with Gil.
That changes the family’s information imbalance. He no longer knows his father only through absence, letters or what other people tell him.
It does not, however, give him an adult understanding of the situation. Knowing that something frightening happened is different from being equipped to deal with it.
This is one of the storyline’s most troubling features: the children gain information through events they should not have to witness.
The effect is not limited to Austin. Georgia’s attempts to control what her children know become harder to maintain, while Ginny must reconsider an action she thought was helping her brother.
Gil’s return therefore changes the relationships between all three members of the Miller family, not only the relationship between the former couple.
Did Gil kill Tom Fuller?
No. Georgia killed Tom Fuller. Austin witnessed her suffocating him.
Gil’s abuse does not make him responsible for Tom’s death, and this distinction becomes essential during season three.
The audience knows one version of events because it has seen the killing. The account later given in court is different.
Keeping those versions separate is necessary to understand the ending. A false accusation remains false even when the person accused has committed other harmful acts.
That is what makes the resolution morally difficult. Gil is dangerous, but he is not the killer in this case.
Why does Austin blame Gil?
Austin falsely identifies Gil as Tom’s killer as part of a plan driven by Ginny to protect Georgia.
The accusation redirects attention away from their mother. Georgia is found not guilty, but the verdict does not change what the audience knows about Tom’s death.
Netflix’s discussion of the season-three finale, published on 9 June 2025, confirms that Gil becomes the person blamed through the children’s intervention.
The distinction between the result and the method is important. Georgia avoids a guilty verdict because the story presented about the killing has changed, not because the underlying event has been undone.
Austin’s involvement is especially significant. His knowledge of what happened becomes something the family can use, placing another adult burden on him.
What does Ginny’s plan reveal?
Ginny’s plan shows her adopting some of the methods associated with Georgia: controlling information, manipulating a situation and protecting the family through deception.
That is an interpretation supported by the creators’ discussion of the ending. Their comments emphasise the consequences of Georgia’s behaviour being reproduced by her children.
The plan can appear effective when judged only by its immediate result. Their mother is free, and Gil is blamed.
But the children have reached that result by creating a false account of a death. The emotional consequences are not cancelled by the verdict.
The finale therefore resists a comfortable reading in which the dangerous man simply receives a deserved punishment. It also asks what the family has taught its children about survival and responsibility.
Why the ending is not a clean escape
Removing an immediate threat does not return the family to the position it occupied before Gil came back.
Austin has witnessed violence, intervened in it and participated in a false accusation. Ginny has helped organise that accusation. Georgia must confront what her children have done on her behalf.
Those changes are part of the ending’s significance. The family’s problems cannot be measured only by whether Georgia is behind bars.
Gil’s storyline brings the programme’s central tension into focus: Georgia’s determination to protect her children can coexist with choices that expose them to further harm.
Recognising that tension does not excuse Gil. It gives the other characters’ actions their full weight.
What is confirmed about Gil’s future?
As of 2 November 2026, Aaron Ashmore’s return was not explicitly confirmed in the official Netflix season-four casting announcements checked for this article.
An announcement dated 5 November 2025 named several returning actors but omitted Ashmore. That does not prove he will be absent.
Likewise, Gil’s importance to the previous ending does not establish that he appears in new scenes. A character can continue to affect a story through the consequences of earlier events.
For now, those consequences are the clearest part of his continuing relevance. Georgia and her children have not simply escaped a threat; they have changed their relationships with one another in the process.
