Wanda and Vision have a complex relationship that's been through many different stages over the course of the MCU's history, and sometimes it can be difficult to keep up with their unique dynamic. The pair were first introduced in Avengers: Age of Ultron, but it wasn't until subsequent projects that their romance truly began to blossom. They're one of the MCU's most entertaining and authentic couples, and their dynamic has allowed for several great moments that stand out within the franchise. Their relationship was most recently explored in WandaVision, which saw Wanda seemingly revive Vision after the dramatic events of Avengers: Infinity War.
Marvel has made several mistakes with Scarlet Witch, but her relationship with Vision definitely wasn't one of them. Despite their differences and troubled pasts, the pair quickly became a fan-favorite couple thanks to their wholesome dynamic and genuine comion for each other. They added a much-needed layer of humanity to the Avengers and Wanda and Vision were integral cogs in the Avengers system, which is why their respective 'deaths' in Avengers: Infinity War left such a gaping hole in the team's dynamic. Those 'deaths' also only added to an already complicated timeline for their romantic relationship from Age of Ultron to WandaVision.
First Meeting In Avengers: Age of Ultron
Wanda and Vision both made their MCU debuts in Avengers: Age of Ultron, but they've actually got much more in common than it might initially seem. During her childhood, Wanda was taken in by Hydra and experimented on using the Mind Stone in Loki's scepter, which made her among the most powerful Avengers in both comics and movies. The very same Mind Stone was also responsible for Vision's sentience and superhuman intelligence. So when the pair first interacted in Age of Ultron, they already had a profound connection that drew them together and potentially sparked their feelings for each other.
Though Wanda was originally raised by Hydra, she quickly switched sides after learning the truth about Ultron's intentions for humanity. She fought alongside the Avengers at Sokovia, risking her life several times to ensure victory for her teammates. Were it not for Vision, she almost certainly would've been killed at the battle. The pair managed to defeat Ultron together, solidifying themselves as a powerful team that will always have each other's backs. It was this shared connection and mutual respect that first brought the pair together, and their recovery from the trauma inflicted by a terrifying villain like Ultron eventually solidified their feelings.
Fighting Each Other In Avengers: Civil War
The first hiccup in Wanda and Vision's relationship came in Captain America: Civil War, when the team found themselves completely divided over the Sokovia Accords. Proposed by the government following the destruction of Sokovia, the accords dictated that the Avengers would be controlled by the military and used at the government's will. Although Vision agreed to sign the accords, Wanda was unwilling to waive her freedom. This caused plenty of friction between the new couple, causing them to briefly part over their differences. They fought on opposite sites at the iconic airfield battle, but their comion for each other eventually outweighed their ideological differences.
Although it can definitely be argued that the MCU split the Avengers up too soon, this issue between Wanda and Vision was extremely important for their relationship. It proved that while they both care for each other greatly, they still have their own thoughts and beliefs that need to be upheld. All healthy relationships have disagreements from time to time, and since they're literally forged from the same cosmic energy, they're bound to come into conflict with each other. But their arc in Captain America: Civil War proved that despite these differences, Wanda and Vision are able to stick together through it all.
Falling Apart In Avengers: Infinity War
Although Wanda and Vision haven't had that many scenes together in the MCU, their relationship has been consistently blooming and developing in the background. The next time audiences catch up with the couple after Civil War is in Avengers: Infinity War, where they're hiding out in Scotland to avoid any unwanted attention following the Sokovia Accords disagreement. Scarlet Witch has been treated terribly for a lot of the MCU, and this peaceful break with Vision was the first (and last) time she was finally at peace. They eventually returned to the Avengers to help fight Thanos, which resulted in Vision's murder and Wanda's erasure from the universe.
Losing Vision was the worst thing that ever happened to Wanda, and the experience couldn't possibly have been more traumatic. Not only did she have to murder her soulmate with her own powers, but the sacrifice was proven to be completely in vain when Thanos rewound time and ripped the Mind Stone from his skull anyway. Wanda had to watch Vision die twice, and that completely changed her mindset on the world. Once she returned in Avengers: Endgame, she was filled with rage and bitterness that dictated the rest of her life from that point forward. Vision was the last thing she had left, and now he was gone.
Bringing Vision Back In WandaVision
WandaVision proved Scarlet Witch's immense strength by allowing her to take control of a whole town in order to forge a fake reality where Vision never died, and the pair lived happily ever after. Though much of the first few episodes is played as comedy, it's actually an extremely tragic story about Wanda's grief and just how far she'll go to be with Vision. In the show, she manifests another version of Vision to share her domestic life with - but things quickly turn sour when he begins to realize the truth. Meanwhile, the real Vision's body is resurrected by the government to help bring down Wanda and free Westview.
The show ends with Wanda voluntarily freeing Westview and allowing the memory of Vision to die once and for all - marking the end of their relationship. Although she was seemingly killed at the end of Doctor Strange in the Multiverse of Madness, Scarlet Witch could definitely return to the MCU in a future project, and the existence of White Vision could cause some real problems for her. The couple's relationship is an extensive and tragic one, but whilst their lives both ended in suffering and heartbreak, it's important to the warm and tender moments that Wanda and Vision had along the way.
