The 'Malcolm in the Middle' theme of this episode is appropriate for the family with three 'brothers'- Tommy (Jett Klyne), Billy (Julian Hilliard), and now Pietro (Evan Peters). The Halloween episode within the hexed reality of Wanda (Elizabeth Olsen) also gives them a chance to donate the classic costumes of their character, including the eventual alter-egos of Billy and Tommy, Wiccan and Speed, respectively.
Since Uncle Pietro arrived home, the twins note their mom has been 'weird' and mention the underlying tension between her and Vision. This becomes evident when Vision (Paul Bettany) says that instead of going with the children, he needs to be with the neighborhood watch. It doesn't seem that Wanda is happy about it, but there is little she can do. Pietro steps up and once again dons his classic Quicksilver costume.
Hayward (Josh Stamberg) continues to throw his weight around, out in the real world. When they question his aggressive actions, he gets Monica Rambeau (Teyonah Parris), Darcy Lewis (Kat Dennings) and Jimmy Woo (Randall Park) off the base. The three recognize that it may be counter-active for them all to attack Wanda, and retaliate to sneak their way back in.
Darcy discovers that Hayward kept data from them, which shouldn't be surprising to anyone. What is surprising, though, is how, with their references, the show continues to be tongue-in-cheek and meta. In a surreal moment, 'Kick-ass' starring Aaron Johnson (Quicksilver in 'Age of Ultron') and Evan Peters is casually name-dropped and repeated by Wanda.
However, the episode has several odd occurrences, the least of which is the interstitial animated advert featuring a guy stranded on an island. Is it intended to show how residents of Westview are trapped with no escape in Wanda's world? Or something more profound? Speaking of which, Vision visits Westview's outskirts, where the powers of Wanda appear to be diminished. It's both unsettling and distressing to see people stuck in limbo, fixed there. Vision briefly takes Agnes (Kathryn Hahn) out of the Hex mentally, but when she calls him an Avenger and says he's dead, she doesn't know what she's talking about. All hope, though, isn't lost. The visits of Monica to Westview resulted in her molecular change, Indica, When Vision steps out of the Hex to begin disintegrating, the episode comes to a considerable turning point. Billy senses something is wrong telepathically and informs Wanda, who then expands the boundaries of the Hex to ensnare the military base and some of its agents, including Darcy.
