WandaVision episode 9 is arriving this weekend on Disney+ and it is going to be the finale of the superhero miniseries. A lot of things will be tackled within this particular episode, including whether or not peace will be achieved for everyone else.

There could be a big showdown between Agatha (Kathryn Hahn) and Wanda (Elizabeth Olsen) in WandaVision episode 9. Ever since the series premiered, the latter has been finding ways to save herself while trying to understand more of her powers.

In episode 8, it was revealed that Wanda has her powers when she was still young -- even before she interacted with the Mid Stone that amplified her abilities. The finale could further explore more about this, and if it is part of a larger narrative in the future.

Agatha was initially believed to be the architect of the Hex instead of Wanda. However, it was revealed that the latter was the one who created her own sitcom world and the former was just a bystander. Now, she is desperate to know how she could wield something like this in the entire town.

Agatha also mentioned her husband Ralph, who hasn't appeared in the series until now. Hahn said that she doesn't know whether this character will show up since the finale has plenty of loose ends to tie. The actress said her character's husband "could make things a little too bloated."

Vision (Paul Bettany), on the other hand, will have his own storyline in WandaVision episode 9, as well. There is a question regarding the "new" version of this character. He was reconstructed by the S.W.O.R.D. and turned into a sentient weapon.

Hayward (Josh Stamberg) is one of the biggest adversaries for the two titular characters. He was the one who assembled an all-white version of Vision and also framed Wanda as a terrorist. He is hell-bent on taking down the latter, which suggests that something deeper is behind all of this.

As for what else is coming in WandaVision episode 9, new villains might be introduced -- aside from Agatha and Hayward. New storylines might be opened and will continue in the second installment, although the renewal has yet to be announced.

Meanwhile, the finale is, reportedly, the longest episode for the series. The previous episode was considered to be the longest one to date, running at 47 minutes. Now, the upcoming episode is 50 minutes long - which included the credits.

WandaVision episode 9 airs on Friday, March 5, on Disney+.
