A year is enough time to break a promise. When My Family left, Fausto had spent his final months trying to engineer a future for the people he loved, deciding who would hold the household together once he was gone and extracting the agreement that they would. The second season opens on the far side of that arrangement, and the arrangement has not held. The clan he tried to secure is coming apart at the seams, the vow they made him is already in the past tense, and the person who arrives to test what remains is not a stranger but the one man who left this family first.

That man is Gaetano, Fausto’s father, and he is played by Sergio Castellitto. The casting is the clearest signal of what the Italian series is reaching for in its return. Castellitto is one of the heavyweights of Italian screen acting and directing, and dropping him into an ensemble built around younger performers changes the center of gravity in every scene he enters. He plays the grandfather who walked out years earlier, the absence around which Lucia built a household and raised her sons, and his reappearance becomes the season’s destabilizing force. The grief here is not measured by who is missing. It is measured by who comes back unwanted, and by how impossible he is to simply turn away.

The show keeps the architecture that made the first season work, braiding the present against the time when Fausto was still alive. Eduardo Scarpetta returns through that earlier timeline, so the dead father stays a living presence rather than a photograph on a shelf — a voice the survivors keep measuring themselves against. The structure does something dialogue could not: it keeps the promise audible, letting us hear it being made even as we watch it fail in the present. The past, in this telling, is more vivid than the present manages to be, which is its own description of how mourning actually works.

Vanessa Scalera anchors the present as Lucia, the mother holding a chaotic house together with one fewer set of hands and one returning ghost from her own past. Massimiliano Caiazzo’s Valerio carries the weight of a brother who inherited a duty he never asked to inherit, and Cristiana Dell’Anna, Antonio Gargiulo, Aurora Giovinazzo, Gaia Weiss and the rest of the returning ensemble keep the family’s specific texture intact: loud, overlapping, quick to wound and just as quick to forgive. It is a household that argues the way some families breathe, and the new season hands it a subject worth arguing about.

What the season is really about sits underneath the plot of a returning relative. It is about the afterlife of an obligation. A promise made to someone who is dying carries a particular force while they are alive to hear it; the question the new episodes press on is what that promise weighs once the person is gone and only the people who made it are left to honor it. Gaetano’s return sharpens the question into something personal and unmanageable. He shares his son’s vitality, the same restless charm, which is precisely what makes him impossible to dismiss and impossible to forgive on schedule. The family has to decide whether its mourning has any room in it for the man who skipped the decades that would have earned him a place in it.

The directors, Claudio Cupellini and Marco Danieli, withhold the easy moral. The obvious version of this story makes the absent grandfather a villain and lets the family close ranks against him; the harder, better version gives him the dead father’s charm and refuses the audience the comfort of a clean judgment. That refusal is the craft signature of the season. Ambivalence is the point. The viewer is placed exactly where the family is placed — unable to either embrace the returnee or cast him out — and the drama lives in that suspension.

This is recognizably the Italian family-saga tradition, the line that runs from Ettore Scola’s portrait of a single household as a portrait of an entire country, through Marco Tullio Giordana’s decade-spanning chronicles, to the collective memory of My Brilliant Friend. These stories treat the family as the smallest unit through which a culture argues with itself, and they refuse to let the surface of domestic comedy harden into sentiment. My Family writes itself into that lineage, laughing through the fall and loving past the pain without ever pretending the pain resolves.

There is a national nerve underneath all of this. In a country where the state is met with practiced suspicion and the famiglia is supposed to catch whatever the system drops, the season asks an uncomfortable question: what happens when the family can no longer catch itself? The promise to Fausto was meant to be the safety net. Its failure, before the first episode even begins, turns the season into a study of an institution under strain — and Gaetano’s arrival raises the possibility that an absent patriarch returning is not a rescue at all but the next stage of the collapse. The family is being asked to do the work the absent man never did.

The return also reads as strategy, and Netflix has done the arithmetic. The first season earned its second outing the practical way, spending a week in the platform’s global top ten with roughly seven million hours watched and around 1.6 million views, and holding a month inside Italy’s daily charts. For a service that has leaned on Italian-language drama to travel across markets, bringing back a proven title and importing an actor of Castellitto’s standing is a calculated upscale move — the kind of catalog drama built to keep working long after its premiere week, in every market where it carries a different name. The fact that the show exists under twenty-one localized titles, from Storia della mia famiglia to its Korean and Japanese versions, is itself the strategy made visible: a story specific enough to feel unmistakably Italian and universal enough to play anywhere a family has ever broken a promise.

What the season cannot answer in advance is whether the people Fausto left behind can become the family he needed them to be, or whether the man who returns will only expose how far they have drifted from the version of themselves he asked for. The promise is already broken when the story begins. Whether it can be rebuilt, and whether the grandfather has any standing to help rebuild it, is the open question the six episodes carry from the first scene to the last — and it is the kind of question the show is wise enough not to fully close.

My Family returns for a six-episode second season, directed by Claudio Cupellini and Marco Danieli, written by Filippo Gravino with Elisa Dondi, and produced by Palomar, a Mediawan company. It streams on Netflix from June 10. Sergio Castellitto joins the returning cast led by Vanessa Scalera, Eduardo Scarpetta, Massimiliano Caiazzo and Cristiana Dell’Anna.
