Marvel Studios confirmed last year that "VisionQuest," the second spinoff from "WandaVision," will serve as the conclusion to the trilogy. Brad Winderbaum, Marvel Studios' Head of Streaming, Television, and Animation, recently explained on Marvel's official podcast how these three series connect thematically.
Winderbaum stated, "In many ways, the exploration of motherhood in 'Agatha: Darkhold Diaries' and the exploration of fatherhood in 'VisionQuest' are intertwined. This entire trilogy, in many respects, is focused on the concept of parenthood."

Winderbaum further elaborated, "In 'VisionQuest,' the contributions of showrunner Terry Matalas are crucial, especially in collaboration with this incredible cast. It truly tells a story about the father-son relationship, and more specifically, the three generations of grandfather, father, and son. Can a man with an abusive father become a good father himself?" Winderbaum was referring to the protagonist, White Vision, whose abusive father is Ultron, his creator. As for the third generation, it presumably refers to Speed, the son of the Scarlet Witch, who is also expected to appear in the series.
"VisionQuest" is helmed by Terry Matalas, showrunner of the TV series "12 Monkeys." The story will follow White Vision, who possesses all the memories originally instilled in Vision but lacks the emotions tied to them. He will explore how to empathize with these memories or forge his own identity. A precise premiere date has not yet been announced.
