Like most of the government agencies depicted in films and on television, the MCU's S.W.O.R.D. isn't quite as noble as it wants citizens to believe. As WandaVision viewers discover over the course of the show, Director Hayward has a hidden agenda — specifically, reassembling Vision's lifeless corpse so he can be wiped clean of his humanity and used as a sentient weapon. He gets his wish toward the end of the season, using Wanda's chaos magic to power up an emotionless (and mostly colorless) Vision 2.0.
Of course, Marvel being Marvel, the introduction of the reanimated Vision sets up some nifty battle sequences between Hayward's sentient weapon and the Vision that Wanda has conjured into being in Westview. But more importantly for longtime Marvel readers, it also calls back to an arc from the comics in which Vision "died" and was later brought back — albeit without the brainwaves that gave his earlier incarnation its humanity. Cold, emotionless, and just as pale as the synthezoid seen in WandaVision, this version of the Vision no longer loves the Scarlet Witch, dividing one of Marvel's most popular comics couples even after half of the pairing triumphed over death.
WandaVision viewers familiar with this storyline will know that Vision eventually gets back to his old self — comics stories are nothing if not a series of shocking changes followed by a return to the status quo — and the show seems to take care of that plot development when the two Visions square off in the Westview town library. After receiving a memory transfer from his magical doppelgänger, Vision 2.0 flies off for parts unknown. At this point, there's no telling where or when he'll turn up next, but it seems pretty clear that we haven't seen the last of Vision.
