CinemaBlend WandaVision currently has a significant number of big questions floating around as the show gets set to wrap up its run of episodes in the next few weeks, but one in particular that has made fans antsy and excited is the mystery surrounding the unnamed aerospace engineer. The character was first brought up by Monica Rambeau in Episode 5 a.k.a. âOn A Very Special Episode,â noted to be a friend who could help with the whole hex situation, and the end of the latest chapter, âAll-New Halloween Spooktacular!â saw Monica and Jimmy Woo hit the road to meet with them. But who exactly is this shadowy scientist, and what could it mean for the future of the Marvel Cinematic Universe?
