Warning: SPOILERS for WandaVision episode 8, "Previously On".

Agatha Harkness, a powerful witch who has been alive since the Salem Witch Trials of 1693.

Of course, Wanda and fans were shocked when Pietro, recast with the Doctor Strange and the Multiverse of Madness, which Scarlet Witch will be part of. Spider-Man: No Way Home may also be Multiverse-centric. In WandaVision episode 6, "All-New Halloween Spooktacular", Pietro fulfilled the TV trope of "long-lost brother causing chaos", and he evaded Wanda's tests of his veracity while providing just enough details about the real Pietro to be ably convincing as the MCU's Quicksilver magically resurrected.

Agatha Harkness spilled the beans about Pietro in absorb much of S.W.O.R.D. based outside the magic bubble's original boundaries.

As Agatha explained, she couldn't resurrect the real Pietro: "Necromancy was a non-starter since your real brother's body is on another continent. Not to mention, full of holes." This confirms Pietro's bullet-ridden corpse is likely buried in the Maximoffs' home country of Sokovia, perhaps with their dead parents, Olek (Daniyar) and Iryna (Ilana Kohanchi). Instead, Agatha used a crystalline possession spell to control the mind of someone who was already in Westview.

So, who is the fake Pietro? His true identity hasn't been revealed yet and, unfortunately, Dr. Darcy Lewis (Kat Dennings) and FBI Agent Jimmy Woo (Randall Park) have been separated and are preoccupied so they haven't been able to crack his identity like they did many other WandaVision cast . However, Agatha via Fake Pietro may have dropped a clue when he was complimenting Wanda on her achievement in Westview during "All-New Halloween Spooktacular": Pietro mentioned that Wanda's illusion for each character is based on their personality underneath. So it's possible the man Agatha selected to play Wanda's "not-brother" is someone's twin brother, an athlete who runs very fast, or both.

The last time Fake Pietro appeared, he caught Monica Rambeau (Teyonah Parris) snooping outside Agatha's house in the end-credits scene of WandaVision episode 7, "Breaking the Fourth Wall". Fake Pietro is likely still under Agatha's mind control and he may even retain Quicksilver's superspeed if he took on the newly-superpowered Monica, but there was no reason to continue the charade of being the resurrected Pietro Maximoff.
