Wanda is alive

First is nanobot Ultron in Horton's estate and he has the original memory chip for Jocasta. While not pictured i bet they forgot to loot the vibranium body and it was left behind.

Second is Doom gigachad TK lifting up the crashed debris and commanding Wanda to 'awaken'. But yes she's back.

I'm guessing that's the black lady that made all the AI.

no one stays dead except Jason Todd

Jocasta (Josephine Carrington) came up with the idea to scan human minds so AIs can use it as the basis for real emotions and also made 20 billion nanobots before dying in 2008 that are apparently better than current year Wakanda tech. She shows up as a female ultron robot hunting down the board members of her company believing she was betrayed and they sold her tech to Stark but her memory is incomplete and she has no idea how she ended up a robot.

The truth is the original human from a century ago (Paul Bettany / Vision template) made the basis for all AI. His son passed away and in his grief he shunned his wife+daughter to focus on building a replacement (also Paul Bettany), funded by preemptively selling all his estate and assets upon his death and abandoning his still-living family. His future grandson (James Spader / Ultron template) from the abandoned daughter would inherit nothing but his grandfather's code notebook, marry Carrington, mind scanned both of themselves to 'complete' AI with emotions, and eventually betrayed her to sell the AI tech to Stark and buy back his Horton family estate.

Years later the Horton grandson was the one hired by SWORD to rebuild Vision. He somehow stole enough vibranium to make the Jocasta robot and transfered her mind scan into the body but she was pissed so he erased all memory of himself leaving her to blame the company board members who likely did nothing wrong. She hunted and killed them to collect all the bio-data needed to unlock the box with her nanobots which is what Horton wanted since he had the last password to open it, he was The Client that hired Paladin, and he has amazing coding powers that let him override both Jocasta and Vision because he's the grandson of the AI founder.

His plan was to erase Vision and upload his mind into the perfect body, make Jocasta his robo-bride-slave, and use the nanobots to control the entire human race and bring peace to the world (showing exactly how he is the human template for Ultron).
