Warning: SPOILERS for WandaVision episode 5.

WandaVision episode 5's cast expands as the Marvel Studios series unravels more mysteries and utilizes key Marvel characters. The first Marvel Cinematic Universe show for Disney+ is now officially past the midseason point for season 1. Five episodes of WandaVision have been released and each adds a few more questions and answers to what is really going on with Wanda Maximoff aka Scarlet Witch (Elizabeth Olsen) and Vision (Paul Bettany).

After largely focusing on what is happening outside of Westview in episode 4, WandaVision episode 5 spends time in and out of the warped city. Inside Westview, Wanda and Vision are figuring out how to raise their twin boys Billy and Tommy and seeing them grow up extremely quickly. Wanda attempts to keep the altered reality in line but Vision continues to question what she's allowing to happen. Outside of Westview, the characters in SWORD further analyze what could be going on and that eventually leads to a confrontation with Wanda in the real world.

With the different points of view in WandaVision episode 5, the cast featured involves most of the main characters the series has used in the past.

Elizabeth Olsen as Wanda Maximoff Aka Scarlet Witch

WandaVision Episode 5 - Wanda and Vision

WandaVision episode 5 once again stars Elizabeth Olsen as Wanda Maximoff aka Scarlet Witch. The episode's debut officially means Olsen has been in more episodes of MCU TV shows than in movies. Wanda's story is focused on trying to be the best mom for her twins, Billy and Tommy, but she also must keep SWORD from interfering with the life she's created. She also steps out of Westview for the first time in the episode. Viewers will recognize Olsen from her past MCU appearances, but she's also known for roles in Godzilla and Wind River.

Paul Bettany as Vision

WandaVision Episode 5 - Human Vision

Paul Bettany returns as Vision in WandaVision episode 5 too. The episode provides more background on what happened to Vision's body after Avengers: Infinity War and before the show began. But, Vision also spends time searching for answers and growing suspicious of Wanda. Bettany has appeared in multiple MCU films prior to WandaVision, and viewers might also recognize him from his work in A Knight's Tale or Solo: A Star Wars Story.

Evan Peters as Pietro Maximoff aka Quicksilver

WandaVision episode 5 ends with a massive Marvel reveal and the return of Wanda's dead brother Pietro Maximoff. However, the show reveals that Evan Peters is playing Quicksilver after previously playing the speedster in Fox's X-Men movies.

Evan Peters can be seen as Quicksilver in X-Men: Days of Future PastX-Men: ApocalypseDark Phoenix, and even a cameo in Deadpool 2. Peters is also known for his roles in Kick-Ass and American Horror Story.
