Serial killer and stalker Joe Goldberg comes to Paris in Season 4 of You, Netflix's drama that follows Joe's murderous ways as he returns to prowl Paris in search of the object of his latest obsession.

Joe tracks Guinevere Beck and several others from New York, where he murdered them, to Los Angeles, where he falls in love with Love Quinn and discovers she is as crazy as he is. When she became pregnant, they married and moved to the suburban nightmare of Madre Linda. In Season 3, Joe and Love had a baby boy, Henry, but their body count only grew. Their strained marriage came to an (literally) explosive end, leaving Joe to seek out his former boss in Paris and stalk his target, Marienne.

Here's what we know so far about "You" Season 4.

Netflix has not yet set a release date for "You" Season 4.

Netflix gave the go-ahead for You season 4 before the third installment was released; on October 13, Netflix released a video announcing season 4. Let's take a look at the show's history. Season 1 aired on Lifetime and had its finale in November 2018. Season 2 moved to Netflix and was released in December 2019.

Season 3 was released almost two years later, in October 2021, which can be attributed to pandemic-related filming delays. Since film and television production is almost back on track, Season 4 could premiere as early as fall 2022.

"You" Season 4 casts Penn Badgley as stalker and serial killer Joe Goldberg.

Based on the events of Season 3, Victoria Pedretti will not be returning as Love Quinn, who was seemingly killed in a violent gas explosion set off by Joe. Of course, Pedretti could appear in flashbacks, dream sequences, or visions.

Joe has disappeared (and is presumed dead), so it is unlikely that most of the characters who appeared in Madre Linda will return in season 4. The main exception is Tati Gabriel as librarian Marienne Bellamy, Joe's boss and the latest target of Joe's obsession. Joe moves to Paris to hunt her down, and as we've seen before, he's good at it.

Joe's return to California may be to check on his son Henry, whom he left in the care of a couple of library colleagues. They are Ben Mair as Dante Ferguson and Noel Arthur as Lansing.

Another past face who may reappear is Saffron Burrows as Dottie Quinn, Love's mother. She was last seen heading to rehab. The last we heard of her was that she had succumbed to Dante and Lansing in a custody battle for Henry. But Dotty is persistent and may show up again.

Finally, Cardi B. may make a cameo appearance in "You" Season 4. The rapper and Badgley have publicly thanked each other on Twitter. And when Jimmy Kimmel asked the actor about a possible Cardi B appearance, he replied, "Um, I don't know, I can never tell. But there's actually - and I think this is true - there's a Change.org petition."

When Netflix changed its Twitter bio to "Petition to have Cardi B guest star in Season 4," the singer responded with her own pitch:

Season 3 ended with Joe living in Paris under the alias Nick. It begins a short time after the events of Season 3, which ended with Joe living in Paris under the alias Nick. He searches for Marienne and her daughter, believing they have fled to the City of Love.

"The entire You team is excited to explore a new darker side of love in Season 4," creator and showrunner Sera Gamble told Deadline.

Even if they can find Marienne and convince her that she is not a psycho, Joe will not settle down for long. Hmmm, this could be an opportunity to crossover "You in Paris" and "Emily in Paris" on Netflix.

And there are still unresolved issues about his son back in Madre Linda. Joe will undoubtedly feel tremendous guilt for abandoning his son in the same way his mother abandoned him.

"I think this is going to shape him from this moment on," Gamble told E. Online.

"And even his exact plan of when and if he will return for his son will be something that [the writers] will get together for hours and hours between snacks to discuss."

Another big question is whether Joe will ever face any real repercussions for all the murders he has committed. We] like to think about the possibility of his punishment," Gamble notes. ''We often end up having theoretical conversations about what the most appropriate punishment is. Should he be killed? No, that's too easy. He should go to jail."
