In Avengers: Age of Ultron (2015), many fans were frustrated by Quicksilver’s (Pietro Maximoff) death. The super-speedster, capable of moving at incredible velocities, was killed by a barrage of bullets while protecting Hawkeye and a young civilian. For years, viewers questioned how someone who could move near the speed of light could be taken down so easily by gunfire.

However, the latest episode of VisionQuest appears to have retroactively fixed this issue.

According to the series, synthezoids like Vision, Jocasta, and Ultron are equipped with advanced quantum processors that allow them to perceive and keep up with super-speed individuals such as Quicksilver or, in the case of VisionQuest, his son Tommy Maximoff (also known as Speed / Célere), played by Ruaridh Mollica.

The show even demonstrates this visually: Vision and Jocasta see Tommy running at what looks like a “normal” speed to them, while in reality he is moving so fast that he’s imperceptible to the naked eye.

VisionQuest finally fixes Quicksilver’s death plot hole after 11 years

This revelation makes Ultron’s ability to eliminate Quicksilver in Age of Ultron much more believable. Ultron, being a synthezoid with the same quantum processing capabilities, could effectively track and react to Pietro’s super speed.

The post has sparked a wave of reactions from fans, with many appreciating the explanation while others still argue the original scene felt unnecessary. Either way, VisionQuest continues to deliver smart connections to the larger MCU timeline, pleasing longtime fans who have waited over a decade for this kind of closure.
