WARNING: Contains You season 2 spoilers
Now that we know season three of Netflix's You is on the way, the details are slowly but surely trickling in.
In the latest, the show's co-creator Sera Gamble offered up a little tidbit, telling fans that 'there's lots to come' with the mystery neighbour seen at the end of the second season.
Gamble made the revelation during a virtual chat with Penn Badgley, who plays lead character and serial killer narcissist Joe Goldberg in the show.
The pair were rewatching and discussing some of the best moments so far, including the final scene of season two - which ended on one helluva cliffhanger.
As we're shown the clip in which Joe peeks through his fence at the unknown woman, Badgley says: "I want to ask you about what we're going to do here but you can't really tell us."
To which Gamble replies: "It's pretty obvious when we were filming this that we were careful not to show too much of her because that role hasn't technically been cast yet.
"But there's lots to come with that neighbour."
Cue the fan theories.
In fact, some viewers have been coming up with ideas of just who that character might be ever since the second instalment aired on Netflix back in December last year.
During that explosive final scene, Joe says in a voiceover: "This is just the beginning. Because this is where I had to be exactly where I had to be to meet you.
"There you were with your books and your sunshine, so close but worlds away. I will figure out a way. A way to get to you. See you soon, neighbour."
Despite sounding like he's found his next obsession, one fan reckons that the woman is actually his mum.
Taking to Twitter, they wrote: "I'm telling y'all the woman at the end is going to be Joe's mom and not a new girl he's obsessed with.
"I think she disappeared and started a new family and Joe finally decided to track her down for obvious reasons... He's absolutely stalking his mom in S3 #YouSeasonTwo."
Others were quick to agree, including one who commented: "Great theory, the woman looks to be possibly married and slightly older. The way her hands and arms look, makes me think so.
"Why would Joe go for a married woman plus one living so close by. He's insane but doesn't seem like something he would do."
Another wrote: "Yo this theory is freakishly spot on. Thought the same thing cause she looked super old.."
Well, guess that's for the creators to know and for us to find out when season three drops.
