Returning from the dead: Quicksilver

There are quite a few MCU characters who could be brought back, despite having been killed in the past "“ as a matter of fact, most of the villains should return, especially Red Skull, via some Infinity Gauntlet magic. After all, Thanos will need some generals.

But this next rumor is about a hero, not a villain. According to the 4chan leak, Quicksilver will be brought back for the Infinity War. Will it be a cameo? It isn't mentioned. However, he’ll be there. And the most interesting possibility would be for Thanos to play with Scarlet Witch's mind, essentially breaking her spirit and driving her insane.

Why would that be interesting? Because it could lead to a House of M type of event in which Wanda reveals her true power and rewrites the entire MCU.

According to the same rumor, Peggy Carter will also return "“ so using visions to play with a hero’s mind it is!
