WandaVision Episode 4: 8 INSANE Fan Theories You Need To See

8. Scott Lang Is Jimmy Woo's Missing Person

There was a potentially big detail revealed towards the start of WandaVision's fourth episode that, thanks to everything that happened after it, was never mentioned again. Jimmy Woo was brought to Westview on a missing persons case, as someone he was supposed to be monitoring in witness protection disappeared.

Even those who knew him had suddenly lost all memory of him in the same way the guards in front of the Westview sign genuinely didn't believe the town itself existed. There is no way this missing person doesn't have a bigger role to play in the series, but who is it?

Jimmy's past appearance in the MCU makes it easy for fans to jump to Scott Lang. He is the only person we have ever seen Woo track before, and though his house arrest sentence was over by the end of Ant-Man & the Wasp, he is still likely to be a person of interest to the FBI.

While it's unclear exactly why Scott would be in witness protection, it would certainly make sense as to why Jimmy was on the case. Should Cassie be in Westview with him, in the same area as Tommy and Billy, this could be the next step in the establishment of a Young Avengers team in the MCU.
