You season 2 may still be without a release date, but co-creator Sera Gamble recently revealed that the much-anticipated second season will chronicle more of Joe's early life.
Based on Caroline Kepnes's novel of the same name, the second season will also be based loosely off the novel's sequel, Hidden Bodies as Joe moves from New York to LA following the murder of his love interest.
Gamble said: "We'll be going into Joe's early life in season two, and naturally we want to know more and move around in his entire life.
"I will say that the whole time we're in the writers' room talking about what that story could be, or what flashbacks or glimpses into his life we might catch, this has been a guiding principle for us; he had a pretty terrible childhood and that does contribute to who he is as an adult.
"But we also wanted to make it clear that a lot of us had shitty childhoods and most of us don't do what Joe Goldberg does - we're trying to walk that line."
The co-creator added that while Joe is 'not a bloodthirsty killer' he is an obsessive psychopath who uses physical force to gain control.
"He doesn't want to kill anyone ever again, but probably in season two he will end up killing someone," she added.
"He's absolutely heartbroken after Beck and he and also we're keenly aware that people are coming to the show after binging season 1 and have all fallen in love with Elizabeth Lail [Beck].
"I think it would be stupid to just slot someone else in. Season one, we're constructing a story that really takes that into account, and no one is going to shove anything down the audience's throats. Joe is really contending with what happened in season one."
The success of the first series, which sees Penn Badgley of Gossip Girl fame play Joe Goldberg, a handsome bookshop owner who becomes obsessed with a poetry student, became one of the show's most popular debut series. The showrunner also revealed to the Hollywood Reporter earlier in the year that, "Part of the fun of continuing the story is that the loose ends from Joe's past are still dangling and could come back to him at anytime.
"He is very worried about the fact that Peach Salinger [the cousin of Beck, murdered by Joe in season one]'s family has hired people to investigate her alleged suicide, and there is evidence potentially still at her house from season one.
"If you look at every act of violence that he does in season one, that is potentially something that could come back and bite him. And Dr. Nicky [Beck's therapist] is in prison and he is ardently protesting his innocence."
After being questioned more on possible storylines, she added, "It's too soon to say definitely whether John Stamos [who plays Dr Nicky] will return in season two, but we have been talking a lot about the character and we're excited to keep telling that story."
