WandaVision Episode 03 Plot Summary and Synopsis
During what appears to be the 1970s, Wanda and Vision have a doctor, Stan Nielson, check on her due to her being pregnant unusually fast.
Nielson explains everything is fine, and leaves, intending to go to Bermuda with his wife. While Vision sees Nielson out, he sees his neighbor Herb cut through the wall.
The couple builds a new room for the baby. While debating on what the name should be – Wanda calling the baby Tommy, while Vision calls it Billy – Wanda suddenly has her pregnancy elevate to six months, then goes through the Braxton Hicks contraction.
This causes her to accidentally generate an energy surge, which shuts down the entire town’s power. She then gives birth to twins with the help of Geraldine. Vision catches Agnes and Herb gossiping and interrupts them.
They talk about Geraldine, and Agnes stops Herb when he stutters repetitively that “She came here because we’re…” Wanda interrogates Geraldine after she reveals she knows Ultron killed Wanda’s twin brother Pietro. Wanda notices that her pendant has a S.W.O.R.D. emblem.
WandaVision Episode 03 Ending
Vision returns to find that Geraldine has disappeared, and Wanda says, “she had to run.” Outside of Westview, Geraldine is cast out from a wall of TV static, then S.W.O.R.D. agents surround her.
