Joe ends up killing her dad. He then tells Kate the truth about his identity, and somehow, she's fine with it?!
She finally asks Joe about his past and he comes clean about his true identity – that he's Joe Goldberg and not professor Jonathan Moore – and it seems to be all Kate needs in order to lead a new life with him.
In Episode 7, Joe tortures and murders Rhys in his country home, in part because Kate's (Charlotte Ritchie) father, Tom Lockwood (Greg Kinnear), blackmails him into doing so, Also, crucially, Joe believes Rhys is the person who's been offing his friends and trying to pin it all on Joe.
He does show possessiveness toward the end of You season 4, but even then, Kate seems forgiving. And Kate's willingness to accept Joe's demons adds another layer to her unexpected fate. To a certain extent, Kate becomes an accomplice to Joe at the end of You season 4, even if she's not fully aware of his past crimes.
Who's the killer in season 4 of You? The ending explained. In season 4, episode five, the 'Eat The Rich Killer' was revealed in a very dramatic scene... it's Rhys Montrose (as we said, kinda)!
Kate knows Joe killed Rhys because Lockwood “made” him do it, so she had the crime scene futzed with so the DNA on the body would be “inconclusive.” Her father, she says, left her everything. She is relying on Joe as a character reference because as long as he is there, she can't be a bad person?!
However, it's soon revealed that Joe never actually knew Rhys, and the version of Rhys who he was talking to, who was cunning and seemingly murderous, was actually a figment of Joe's imagination.
When he wakes up in hospital, Kate is there and he confesses that he's killed people and that his real name is actually Joe Goldberg. But Kate seems fine with it! She knows he's murdered people and she doesn't care! She loves him!
To give a brief summary of Part One's events, the season picked up where Season 3 left off. Joe left Los Angeles—where he faked his own death, blamed it on Love (literally and figuratively), gave his son Henry to their neighbors, and fled to Paris in search of Marienne, his one true love (this time for real).
Kate shows up at Joe's doorstep and invites him out for drinks, but Joe turns her down because he knows what their outing will lead to. He explains to Kate that if they get together, she'll eventually want to know more about him and his past, and he can't allow that.
Rhysand gives her his power, and in doing so, knowingly gives his life. The Cauldron is fixed, but Feyre is distraught and demands that the other high lords resurrect him, like they did for her. They all do, including Tamlin, and Rhysand is brought back to life.
While Joe has plenty of reasons to hate his alter Rhys, he never meets Rhys Montrose in Season 4 of You until their deadly encounter. The two men only make acquaintance when Joe knocks on Rhys's door, ties him to a chair, tortures his genitalia, and kills the writer.
The cauldron willed it? He does not only have highlords powers he has natural magic before he was crowned. So it's likely being crowned amplified is natural abilities a lot.
It was revealed that Kate was the one who worked on the business deal that gave several children cancer ("Good Man, Cruel World"). It was mentioned by Tom Lockwood that Kate is one of seven children ("She's Not There").
Throughout the show, Joe also fell back into his old ways and became obsessed with Malcolm's girlfriend, Kate. While he was also trying to protect her from his stalker's threats, he also found himself becoming the newest member of their elite group of friends.
Peach was perceptive and she quickly realized there was something off about Joe and his ways. And when some of her belongings started disappearing — like her laptop and a book from her home — she suspected Joe was the culprit.
In later seasons, currently being season 4, Joe is a murderer on the run and it was revealed that he has erotomania although it was obvious in the earlier seasons that the character is troubled, more so for his troubled childhood and his need for affection.

She made him his favorite meal, roast chicken, and confronted him about his affair. Joe in turn revealed that he knew about Love's affair and asked for a divorce.
Kate isn't a fan of Joe from the get go, and acts very rude and blunt to him, firstly because of her upbringing making her that way, and secondly because she worries that he may be taking advantage of her best friend Phoebe, who Joe meets on a night out, and who is much more naïve and trusting.
Now that Part 2 of You season 4 has dropped on Netflix, we have an answer for Love's unexpected appearance in the preview. Unfortunately, no, she is not alive.
After she finds evidence that Joe is the real Eat the Rich Killer, Joe frames Nadia for the murder of her boyfriend, Edward. Scared for her life, Nadia stays silent about Joe's crimes, and accepts her prison sentence.
Rhys is another alternate personality, and also Professor Moore. After he did that, Rhys's character was created to impersonate the evil inside him: Rhys was staging the Eat The Rich Killer, but it was actually Joe the one who killed everybody.
Rhys becomes Joe's alter-ego and exists in this form only after the latter chokes the life out of the original model. YOU Season 4 part two concludes with Joe tying up a series of loose ends.
Episode 5 of Season 4, "The Fox and the Hound," reveals that Rhys Montrose, a bestselling author always in the background of the rich people's parties, had orchestrated the murders, attempting to frame Joe for them after discovering who he really was.
