A VisionQuest mystery has quickly been put to rest.

After an emotional journey for White Vision (Paul Bettany) and his encounter with his son, Tommy Maximoff (Ruaridh Mollica), it reaches a satisfying conclusion, reuniting most of the Maximoff family and helping the lost Avenger finally make peace with his grief. However, the most talked-about moment was VisionQuest's post-credits scene that confirmed Elizabeth Olsen's Wanda survived the temple's destruction, with Robert Downey Jr.'s Doctor Doom present to take her.

While that set-up to Avengers: Doomsday broke the internet, a few curious viewers noticed that Doctor Doom didn't sound like Downey's voice. Thankfully, it didn't take long to get a response, as VisionQuest creator Terry Matalas provided a definitive answer to those who suspected. In an interview with Gold Derby, he confirmed "that's Downey's voice" in the surprise post-credits scene.

However, the showrunner didn't elaborate further on the surprise reveal, since he wasn't directly involved in filming that moment and said, "I don't want to give away" anything that could spoil Avengers: Doomsday. Matalas wrote and directed the finale. Still, he knew that Wanda was a "missing component of that finale," titled "Forever." The team felt the surprise revelation "felt the biggest promise of more for everybody" and "came together really fast."

"I can't talk too much about how it was constructed, because I don't want to give away, but yes, that line was designed for this moment, specifically."

"It was something we all knew that we had to have. She was the missing component of that finale, and we talked about a dozen different ways to bring her back. This was the one that felt like the biggest promise of more for everybody. It came together really fast, and was really collaborative in a very fun way."

For four years, the Scarlet Witch's fate was up in the air after Doctor Strange and the Multiverse of Madness seemingly implied shedied in the falling rubble. Even Olsen has stated repeatedly that Wanda likely died and put on record that she wasn't in Avengers: Doomsday.

Now, the VisionQuest post-credits scene changes everything ahead of the highly anticipated Avengers movie, setting up the Scarlet Witch's return, likely under Doctor Doom's control. Even before the surprise came to light, plenty of fan theories suggested one of the Latverian Witches was the Scarlet Witch, especially as multiple posters highlighted their importance.

Scratch & Peek

Seven years after Tony Stark died in Avengers: Endgame, Downey marks his return to the Marvel Cinematic Universe, but this time as the iconic villain Doctor Doom. Avengers: Doomsday trailers have already sampled his Latverian accent for the antagonist, which is a stark contrast to his voice as Tony.

It's unclear why Doctor Doom sounded different, though it's now confirmed that Downey does the voice, and it wasn't a stand-in or a hint of another variant. Nevertheless, it has raised eyebrows about whether that was intentional or just a matter of tweaking Downey's voice before the movie's release.

Meanwhile, given that VisionQuest features multiple close AIs of Tony Stark, Matalas addressed why Iron Man, and, by extension, Downey, didn't appear in the series. While speaking with The Brandon Davis Show, he first attributed it to cost, noting that a "television show budget" is different from movies'.

Still, he had envisioned an idea that would have shown him talking to Katerina Wells, revealing an "old Tony" before the Jericho incident. He acknowledged that "it would have been a big ask to get Downey to come in and do it."

All eight episodes of VisionQuest are streaming on Disney+. Avengers: Doomsday will be released in theaters on December 18.
