In Concept Art WandaVision Reveals A Deleted Quicksilver Scene
A WandaVision deleted Quicksilver sequence, which would have enhanced Evan Peters' involvement in the series finale, has been shown in newly released concept art
Even though Aaron Taylor-Johnson played the MCU's Quicksilver in Avengers: Age of Ultron, Peters made a surprise appearance as Wanda's long-dead brother Pietro in WandaVision episode 5, "A Very Special Episode..." Beginning with X-Men: Days of Future Past, Peters played Peter Maximoff in Fox's X-Men franchise. Many fans assumed Peters' involvement in the MCU as an alternative franchise character meant the multiverse and future crossovers were confirmed; however, later in the series, it was revealed that Peters was actually the witch Agatha Harkness's neighbor, Ralph Bohner.
A WandaVision deleted Quicksilver sequence has been revealed in new concept art provided by artist Chris Nichols. Darcy Lewis (Kat Dennings) cares to Ralph, who kneels at the edge of Agatha's cave, which holds the Darkhold, a huge evil power spell book. Tommy and Billy, Wanda's twin boys, stand at the far end, disappearing from view. Here's some of the initial concept art:
The original WandaVision Quicksilver scenario saw Tommy and Billy bringing Darcy, Monica Rambeau (Teyonah Parris), and Ralph down into Agatha's basement to fetch the Darkhold in an effort to stop the witch, according to director Matt Shakman. They are ambushed by Agatha's rabbit, Seor Scratchy, before they can reach the book. The rabbit seems harmless at first, until it morphs into a monster. The sequence was removed because it detracted from the fundamental tension between Wanda and Agatha at the series' conclusion, according to the director.
Following Monica's release from Agatha's spell, the deleted Quicksilver scene would have extended Ralph's participation in the series finale. Wanda's twins depart from their mother's construct, despite the fact that the concept illustration does not show Agatha's demon bunny or Monica. Wanda would have put her boys in bed before collapsing her constructed world in on itself in the final episode, thus their "death" would have occurred sooner. Although fans were split on the WandaVision X-Men Quicksilver spoof, the show's ambitious plot established the basis for Doctor Strange in the Multiverse of Madness and the MCU's Phase 4 in the future.
