*MAJOR SPOILERS FOR EPISODE FIVE BELOW*

Wanda's reality-warping ability has hit a snag - is someone else manipulating her world too?

Oh boy. Even before that shocking ending, there was a lot of happenings to unpack from 'WandaVision' episode five. And now we've to wait a full week until we get a follow-up to what went down.

Before we cut straight to the ending, it's important to note what happened in the lead up to the big reveal. We've levelled up to an '80s sitcom this week ('Family Ties' being the inspiration here - and what a theme tune might we add), and returned back to suburbia where Wanda (Elizabeth Olsen) and Vision (Paul Bettany) are having difficulty with their newborn twins.

Agnes (Kathryn Hahn) calls over in full '80s garb when a strange exchange between herself and Wanda sparks Vision to question what is happening around him. Wanda begins to lose track of herself, while Tommy and Billy age 10 years and get a new pet, Sparky.

Simultaneously, the outside forces at S.W.O.R.D. are working away, attempting to break back into Wanda's perfect Westview reality, where she has thousands of people captured. It is also revealed that Wanda stole Vision's lifeless body a number of days beforehand - confirming again that yes, Vision is dead. All hands are also pointing to Wanda being the main antagonist of the series.

When S.W.O.R.D. manage to break back into Westview, this leads to Wanda breaking ranks. Momentarily leaving her "Hex", she threatens the agents, particularly acting director, Tyler Hayward (who we don't know if we should trust). It's nice to have these two worlds work alongside each-other now - it does mean we're getting ever-closer to figuring all of this out.

Before we get to the ending of the episode, it's important to pay attention to the 'Lagos' commercial break. Spilt red liquid calls for a super-absorbent kitchen roll, "for when you make a mess you didn't mean to". This is a reference to when Wanda set off an explosion in 'Captain America: Civil War', killing innocent people and resulting in the "superhero registration" act, The Sokovia Accords. She's still holding onto this guilt.

Finally, the biggest surprise of the episode is one that was rumoured for a very long time. Evan Peters was spotted on the set of 'WandaVision' last year, which leaked to the press, sending us into speculation overdrive. The actor made his grand appearance in the final 30 seconds of the episode (complete with "WOOOO!" from the audience).

Peters played Quicksilver in Fox's 'X-Men' franchise, so how could he appear in a separate universe as the same *deceased* person? Aaron Taylor-Johnson, who played Pietro Maximoff during 'Age of Ultron', is killed off, ending his one-movie story arc. No-one was that upset about it really, not even Wanda. The far-superior Peters version of the character was praised by fans during his 'Days of Future Past' debut, and ended up returning for 'Apocalypse' and 'Dark Phoenix'. But... could his arrival mean that mutants now exist in the world?

What we think is happening at the very end of 'WandaVision' episode five is, and bear with us here, there's someone else pulling the strings. From what we can see throughout the series so far, and this episode in particular, Wanda has a monopoly over everything we see. But, she didn't know who was going to be at the door, did she?

Although Wanda's abilities allow her to grapple with reality and bend to her will - there was one moment in this episode where she did not have control. When Vision was at work, he was able to snap his colleague Norm back to himself, which Wanda wouldn't have bargained her husband would ever do. Taking this and running with it, could Vision have manipulated a version of Pietro to mess with Wanda's mind? He admitted during this episode that he cannot remember anything before his life in Westview - so he would never have known what Wanda's dead brother looked like.

Fans reckon that this could be the introduction of mutants and the X-Men that we've been waiting for - but our jury is out on this one. Quicksilver could just be a figment of Wanda's imagination, one which she is not even able to control. As we've been told, everyone in Westview is real. So, how can Pietro be too?

Just when we thought we were getting somewhere with the plot, along comes Even Peters and messes things up. Episode six has a lot of explaining to do.

If you're into your comics, there's this (now hilarious) snippet of an interview which has surfaced on Reddit where Elizabeth Olsen laughs at the idea of the 'House of M' storyline coming to life on-screen during an interview. Who's laughing now, huh?

The first five episodes of 'WandaVision' are streaming on Disney+. The final episode of the series will air on March 5.
