You know, it never struck my mind before, but... where is Nebula's body? Is it possible S.W.O.R.D. has her body & are using it to further their agenda?
From what we know, Vision died in 2018, and sometime between 2018-2023, S.W.O.R.D. took Vision's body and refocused from sending people to space, into developing A.I. & robotics. In that footage from episode 5 on WandaVision, it seemed like they had dismantled Vision's body into pieces to study, analyze & reverse-engineer to create sentient weapons.
Wanda has taken Vision's corpse, but what about Nebula? 2023 Nebula shot alternate 2014 Nebula in the heart, and her body was left in the Avengers HQ tunnel. It seems like after the Battle of Earth, the Avengers all went their separate ways, and the ruins of the New Avengers Facility were left as-is (it took ages to clean up Battle of New York, so these ruins aren't gonna be cleaned in 3 weeks, which is how long after Endgame that WandaVision takes place).
Our heroes just left those ruins, and I'm sure the government would wanna take a look, send guys in hazmat suits, check for any alien materials left behind. S.W.O.R.D. walks into the tunnels, sees alt. 2014 Nebula's clearly bionic body... and they would retrieve it. What if that's how SWORD continues their robotic/sentient weapon work since Vision's body has been taken? Just a though that popped into my mind that I wanted to put out there.
