The moment we've been waiting for finally came this week. After an agonizing countdown, You season 2 dropped on Netflix in what was probably the best belated Christmas gift we could have asked for - leaving many fans in a full-blown Joe Goldberg induced frenzy.

As viewers sink their teeth into the new offering, it seems many can't look past one thing - and it's caused Twitter to be flooded with memes.

But the final twist in season 2 has left some viewers with a pretty terrifying theory. Read on for all the juicy details - and be warned, there are spoilers ahead.

Netflix's You hit our screens on December 26th of last year.

Perfect for those in the post-Christmas slump, the psychological thriller followed the ill-fated romantic pursuits of a terrifying sociopath, named Joe.

It was based on the 2014 novel of the same name by Caroline Kepnes.

In the series, Joe becomes absolutely obsessed with a writing student and all-around Millenial cliche named Guinevere Beck, stopping at nothing to gain her affections.

Some of Joe's actions are pretty questionable.

And by questionable, we mean terrifying. What starts with him intensely investigating Beck's social media accounts quickly descends into some full-blown stalking. The girl seriously needed to invest in some curtains.

And it got worse...

By the end of series one, not only were all of Beck's closest acquaintances murdered but (spoiler alert), Beck had to go too. She simply knew too much about Joe's horrifying habits.

Because you can't get away with this stuff forever, right?

Although (worryingly enough), Joe seems to have managed to go on a full-blown killing spree without consequences - and there was an even more bizarre reaction to his behavior.

Because in spite of the fact Joe Goldberg was a stalker and murderer?

Yep, that's right. Pretty much the whole of the internet developed a huge crush on him. This is why we can't have nice things.

After the trail of destruction Joe left behind in New York, season two of You has had to have a change of scenery.

It first starts with Joe moving cross country to Los Angeles, with the best intentions to turn over a new leaf and leave all the creepiness and crimes back in NYC.

And with a new city, comes a new love interest.

As Beck is (sadly) no more, Joe obviously needed a new victim - sorry, sorry, girlfriend. Earlier this year, it was announced Love Quinn would be played by Victoria Pedretti.

But there are some recurring characters.

Joe's mysterious ex, Candace, who we believed for all of season one to be dead, came back for season two!

The second series of You is based on Kepnes' follow up book.

The second book, called Hidden Bodies, came out in 2016.

Fans of season one were always going to be in for a treat with this second season.

"Joe is always trying to be a good guy but yet somehow he's finding himself in these thriller, horror kind of situations. It's terrible for him but I think it's going to be so much fun for the audience," Gamble says.

But that's not all.

Gamble promised a scene in season 2 which will make the entirety of season one seem like easy watching.

It's clear Gamble enjoyed making the second series.

"Episode two of the season has my single favorite shot that I have been a part of in my entire career," she teases.

It's safe to say everyone was excited to get creeped out by Joe once again.

And fans have shown no hesitation in getting stuck into binging the latest offering.

And it looks like it hasn't been disappointing so far.

The reviews are in and people seem to be well and truly raving about the second installment.

But there's one thing people can't help but notice.

Penn Badgley, who plays resident psycho, Joe in the series, was best known for his role as Dan Humphrey in Gossip Girl (which is actually coming back to screens very soon - get all the details at the end) and many fans are pointing out how You is just Gossip Girl 2.0.

Many can't believe that You's Joe Goldberg and Gossip Girl's Dan Humprey are different characters...

Fans find their personality so similar that they are convinced they are just the same person.

And it's become the focus of some hilarious memes.

Just wait until you see the last one...

People just couldn't help themselves.

The Gossip Girl memes kept on rolling in. Also, how crazy was A Simple Favor starring Blake Lively?

The resemblance is definitely uncanny. 

Looks like many people can't look past the star's former role.

Given the fact that Dan was Gossip Girl and a stalker...

We're not entirely surprised either.

Some fans have even come up with their own theories...

This all makes sense now.

But for those who've watched it, the second series has left more questions than it answered.

Quick catch-up - after realizing Love is as crazy as him, Joe and her seem to settle down into a nice suburban life together.

But (obviously) everything is not what it seems.

In the final shots of the final episode, we see Joe looking through his fence at a new lady.

"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," he says.

"I will figure out a way: a way to get to you. See you soon, neighbor."

People had some strong feelings about the twist.

Were we all stupid to think Joe might finally have settled down and stopped his murderous ways? (Clue: yes.)

Viewers were left annoyed.

But on top of that, there was one big question. Who, exactly, was that mystery woman?

Well, some have a very interesting theory.

Rather than a brand new "love" interest, some are speculating the character is actually Joe's mom.

There's a fair amount of evidence to support this, too.

Like, would Joe really go through everything with Love just to immediately have his head turned?

And that's not all.

The hands seen holding the books look more like they'd belong to an older lady - rather than another of Joe's contemporaries.

Many totally buy this theory.

And, let's face it, it'll make for a truly incredible season three.

But that's not all.

Some fans are holding out for a Beck and Joe reunion. It seems kind of unlikely - but hey, we only have to wait a year to find out. Sigh. But for more exciting Penn Badgely content, scroll on for all the details on the brand new Gossip Girl.
