Endgame Theory Makes Cassie Lang’s MCU Story Even More Heartbreaking
An Avengers: Endgame theory for Cassie Lang makes her Marvel Cinematic Universe story even more heartbreaking. Scott Lang’s daughter has been part of the MCU since 2015’s Ant-Man, but she has changed a lot. After being a minor figure in the first two movies, Ant-Man and the Wasp: Quantumania features an older version of Cassie Lang, played by Kathryn Newton as the character is recast again. The movie will play a key role in shaping her future, including making her a superhero before joining the Young Avengers, but it could also be influenced by what happened in Avengers: Endgame.
Ant-Man plays a vital role in Avengers: Endgame, as his escaping the Quantum Realm paves the way for the Avengers to crack time travel and plot a time heist to steal the Infinity Stones. Cassie Lang is only featured in a few scenes in the movie. She is reunited with Scott after he returns to Earth and discovers that five years have passed since he entered the Quantum Realm in Ant-Man and the Wasp‘s post-credits scene. It’s an emotional scene between the father and daughter, and it might be an even more heartbreaking moment for Cassie Lang’s MCU story, according to some theories.
Ant-Man’s reunion with Cassie Lang in Avengers: Endgame is one of the film’s more emotional moments. The emotion from Scott comes from a few different areas. On the one hand, he is thrilled to see that Cassie is alive and was not snapped by Thanos like Hope van Dyne, Hank Pym, and Janet van Dyne were. However, there is also some sadness to see that his little girl is all grown up now. At this moment, Scott realizes how much of her life he missed while being stuck in the Quantum Realm, and Scott already regrets that he already missed so much time with her while in prison.
The emotion on Cassie’s side of her reunion with Scott is much more a sense of joy. The Ant-Man movies established that she really looks up to Scott and that they have a great relationship despite the time apart. Avengers: Endgame‘s reunion shows Cassie’s reaction to learning that Ant-Man didn’t die and the surprise to see him for the first time in five years. She is thrilled to have Scott back at this point, and there might be an even more heartbreaking reason why Cassie is so happy to see him.
One Avengers: Endgame theory suggests that Cassie Lang’s mom and stepdad were snapped by Thanos. Maggie Lang (Judy Greer) and Jim Paxton (Bobby Cannavale) have minor roles in the first two Ant-Man movies, but they are not featured in Avengers: Endgame. This is somewhat strange considering Cassie lives with them in the MCU. While bringing Greer and Cannavale back might not have worked for the movie’s production, their absence from Cassie’s scenes is noticeable. It also creates room for the theory to develop that Thanos snapped Cassie’s mom and stepdad to explain why they are missing.
If the Avengers: Endgame theory that Cassie’s parents were snapped is correct, it means that she was completely alone for those five years after Thanos’ snap. Maggie and Jim were snapped, while Scott was presumed to have met the same fate while trapped in the Quantum Realm. Without any other close relatives, Cassie would have lost her entire family in a single heartbreaking moment. That could then add more emotion to Cassie and Scott’s reunion in Avengers: Endgame, as it would be when she discovers one of her parents is still alive.
The theory that all of Cassie’s parents were snapped in Avengers: Endgame could help set up her story in Ant-Man and the Wasp: Quantumania. The Phase 5 MCU movie has teased in its marketing that Cassie is following in Scott’s footsteps in terms of getting in trouble with the law. Footage has shown Cassie being released after being detained or arrested. While the reason for Cassie’s criminal behavior has yet to be revealed, it is possible that the time she spent alone or in the foster system during Avengers: Endgame could have pushed her to a life of crime to fend for herself or earn some extra money.
Furthermore, if Cassie’s parents were gone during Avengers: Endgame‘s five-year time jump, this could connect to her building a device that could communicate with the Quantum Realm. She could have hoped that Ant-Man or someone else she knows got stuck there. Cassie wanting to communicate with the Quantum Realm would then be an act of trying to be a hero and save her father, Hope, Hank, or Janet. Little could she know that it would draw out Kang the Conqueror.
