Mooney (Mark Blum) adopted Joe (Gianni Ciardiello), took care of him and gave him a job at the bookstore.
He is the owner of a book store named after him called Mooney's. He was the abusive foster father of the show's protagonist Joe Goldberg.
Greg Kinnear (House of Cards, You've Got Mail) will guest star in Part 2 of Season 4 as Tom Lockwood, aka the father of Joe Goldberg's (Penn Badgley) latest love interest, Kate Galvin (Charlotte Ritchie).
He cared for him but also was abusive to him believing that he was guiding him. He would often lock Joe in his glass cage in the basement to teach him various lessons, telling him that he is doing it out of love and to make sure Joe does not end up like his father.
The book store's owner, Mr. Mooney, would lock Joe in the cage as a young boy to punish him.
Not only was the angry old man still alive, but he was also severely physically disabled. Joe confessed to Beck, in what seemed like an emotional moment at the time, that Mr. Mooney had a debilitating stroke that left him paralyzed and mute.
Will is able to convince Joe that he has no intention of turning him in if he releases him, that he just wants to go to Manila to be with his girlfriend who he met on the internet. Joe decides to let Will out believing the promise that Will won't tell anyone about Joe's true identity.
Joe is a loner bookstore manager who becomes infatuated with a woman named Guinevere Beck and begins to stalk her to find out everything about her and hopefully make her fall in love with him. However, his obsession soon becomes out of control when he starts trying to control every aspect of her life.
Like the women in seasons past, Joe had formed an unhealthy obsession with Rhys that escalated to a boiling point. And though Joe's sanity was virtually non-existent by this point, Badgley liked the Rhys and Joe dynamic.
Joe is a serial killer, stalker and former bookstore manager who, upon meeting Guinevere Beck at his workplace in New York, develops an extreme, toxic and delusional obsession with her.
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.
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).
Edward Beck is first introduced as The Captain in the third episode, Maybe, where Joe initially suspects him to be a solicitor of Beck. Tt is not until Joe follows Beck to the motel she stayed at that it is revealed he is actually Beck's supposedly dead father.
Joe asks her what's wrong with him for her to leave him, if it was him killing his father, to which Sandy replied that she made too many mistakes and was hurting, in need of starting over completely. With that, she and Jakey left Joe, never to be seen again.
Joe's young neighbor, Paco, ends up moving to Los Angeles with his mom after Joe kills his mom's abusive boyfriend, Ron. Throughout season one, Joe shows his kinder side by befriending and helping his young neighbor Paco, who lives next door with his mom, Claudia, and her abusive boyfriend, Ron.
Joseph Goldberg (Penn Badgley) is a bookstore manager at Mooney's who stalks and dates Guinevere Beck in the first season. In the second season, he goes by the name Will Bettelheim and works as a bookstore clerk at Anavrin, and stalks and dates Love Quinn.
Joe ends up killing her dad. He then tells Kate the truth about his identity, and somehow, she's fine with it?!
Upon arriving in London, Joe develops such an obsession with Rhys after reading his autobiography, A Good Man in a Cruel World, which Joe closely identifies with. Then the hallucinations start. “He's really desperate to see himself as a good person,” says Gamble.
So why did Joe kill Love? Because he wanted to break up with her, tired of living with a killer and keep hiding the bodies she killed, because he wanted to start a new life with Marienne, and ultimately because Love attempted to kill him.
That particular true love? Love Quinn, Joe's better half for Season 2 and 3, played by the amazing Victoria Pedretti. Unfortunately for Joe, he completely rejected Love when it turned out that she was perfect for him—meaning she was also a manipulative murderer with a huge ego and a short temper.
Rhys becomes Joe's alter-ego and exists in this form only after the latter chokes the life out of the original model.
Love dies from the aconite. With her final words, she tells Joe they're perfect for each other, but bad for their son. Ever in cleanup mode, Joe spins an elaborate plot to once again flee a major American city. He chops off two of his toes and bakes one of them into a pie.
Joe hates men, and he has a history of wanting to protect women. But, of course, he'd prefer a daughter over a son. Also, Joe doesn't want to raise a son to become like him.
While we never saw Beck's death in Season 1, she visits Joe in a new episode (in his mind, anyway), and reveals that he brutally strangled her.
