Warning: This article contains spoilers from VisionQuest episode 8.
The series finale of Marvel Studios' VisionQuest was full of surprises. Some of them had been rumored for some time while others completely caught us off-guard. But all in all, the finale delivered in every way imaginable, sending the WandaVision Trilogy out on a high as strong as the one that it began on. And we couldn't have asked for more (or better) than that.
One of the biggest moments from the episode, titled "Forever", was the return of Billy Maximoff (Joe Locke). The magical son of the Scarlet Witch and Vision made his long-awaited comeback when his brother Tommy connected with him via Billy's dreambinding spell, leading to an emotional reunion for the Maximoff brothers. It also led to a moment that raised some eyebrows as fans pondered who he invisible person Billy was talking to actually was.
Ghost Agatha Harkness remains Billy's guide
When Billy reveals to Tommy that he is in New Jersey and can't make it to London in time to save Vision, he turns to his right and speaks to someone who isn't there - prompting a conversation about portals, suggesting that his training has hit a snag. But who is this mysterious voice training Wanda Maximoff's son? Why it's none other than Agatha Harkness herself, of course.
If you'll recall, the William Kaplan reincarnation of Billy was introduced via Agatha All Along, the first WandaVision spinoff. Kathryn Hahn led that Disney Plus series, reprising her role as Agatha from WandaVision as the ancient witch accompanied Billy down the magical Witches' Road. Although Agatha was as self-serving as ever throughout, she developed a soft spot for Billy and ultimately sacrificed herself to save him from Death - becoming a ghost in the process. And, from that moment on, she became his mentor, accompanying him on his journey to find Tommy. As The Ballad of the Witches' Road goes: "Spirit as my guide"
Although an Agatha cameo was rumored for VisionQuest, Hahn didn't reprise the role, with the show's more grounded tone allowing for Agatha to be represented via supernatural whispers instead. It proved that she had remained by Billy's side after all this time without us having to physically see her. And given that Vision had spent most of the series talking to AIs in his head, it was rather fitting that Billy got to talk to his "imaginary friend", too.
Showrunner Terry Matalas confirmed that there were never conversations to have Agatha actually appear, telling Entertainment Weekly that "We couldn't afford that... That wasn't ever really an option." He did, however, love the idea of having Billy speak to her, adding that it wouldn't have made sense for Tommy to see her. And, as VisionQuest had more of a grounded tone, an old-fashioned house-haunting transparent ghost might not have fit with the aesthetic (even if we would have totally forgiven that to see Agatha again).
The good news is that Tommy, Billy, and Vision are together again, with the potential for a reunion with Wanda herself down the line. We don't know what the future holds for these characters as the MCU prepares to head into the double act that is Avengers: Doomsday and Avengers: Secret Wars but we do know that we will see the Maximoff family again down the line - and that means that there will be plenty more opportunities to see Agatha too.
Kathryn Hahn has made it clear that she is ready to reprise the role in the MCU's future, so it's only fair that we get to see more of the beloved witch as she guides and trains Billy. Heck, if and when Wanda and Billy reunite, the Scarlet Witch needs to see that it was Agatha who helped her son reach his full potential. And if anybody in the MCU should be able to see ghosts - especially witchy ones - it should be Wanda.
Although we didn't physically see Agatha on our screens, it's good to know that she's stuck by Billy's side, offering advice, guidance, and ultimately helping him learn how to open portals. So, if you found yourself wondering who the voice he was speaking to, we have only five words for you: It was Agatha All Along!
