Is Vision Alive?

In the fourth episode of WandaVision we see Wanda looking at Vision after using her powers to send Monica back to the outside world and he looks just like he did right after he died five years ago (which was about three weeks ago from Wanda's perspective). 

This brings the question to the forefront we have all been asking since the show started, "Is Vision really alive?" I think there are three possibilities:

1. He is alive but his animating energy is coming from Wanda, not the Mind Stone
2. He is alive and has a new power source (arc reactor?) or stone (in the comics he has the Sun Stone in his forehead).
3. He is dead and Scarlet Witch is just imagining him as alive

It seems that #3 is not true because Vision seems to have a mind and personality all his own as he is seen questioning the strangeness of Wanda's reality several times until Wanda asserts control again. So most likely either he has truly been brought back to life by Wanda (perhaps as her powers come from the Mind Stone she can create a reasonable facsimile to resurrect him), or somehow he was brought back to life in the five years since the Snap.

As Vision did not appear in Avengers Endgame it seems that he was NOT brought back to life by Bruce Banner or Tony Stark, but there doesn't seem to be a good reason WHY they didn't bring him back. It is weird that Vision just stayed "dead" after the Mind Stone was pulled from his head. I mean it's just basically like if you took the battery out of your toy, right? Couldn't Tony have just made a new arc reactor for him? It doesn't make sense that Shuri, Bruce, or Tony wouldn't have fixed him, but I guess Shuri was blipped out and Bruce and Tony were traumatized so they didn't think to resurrect him.  

I know part of his personality was from the stone, but he should still have his Jarvis personality, he would just not have emotions. (A similar thing happened to him in the comics.) It's not like a robot has to have their brain in their head. (It wouldn't make any sense actually; you would want his brain to be in like a bullet-proof black box deep inside his chest cavity or something, right?)  

So it makes sense that he could be back alive, it's kinda weird that Wanda didn't just . I hope we see the scene where Scarlet Witch goes to the warehouse with his body. Perhaps she is so overcome with grief she goes nuts. Maybe since she is not a tech person she didn't think about calling Shuri and having her fix him. It has only been three weeks (for Wanda) that she was in Wakanda and talking to Shuri who was sure she could remove the stone and save Vision's brain.  

 

 

 

 

In Infinity War Shuri says the Mind Stone is attached to "3 trillion neurons" in Vision's body (but it could be that the Mind Stone itself has the "3 trillion neurons" but that doesn't really make sense). Shuri says that any slight miscalculation when removing the stone could be catastrophic. It seems the obvious thing to do would be to make a backup of Vison's mind before she started to try to disconnect the stone safely. (If you were going upgrading your PC you should backup your data first, right?)

If Vision is not "really" back alive from Scarlet Witch's magic, then hopefully they contact Shuri and she can help make a new stone (Sun Stone?) for his power source and restore the backup she made before she started her procedure.
