Quicksilver returns

This is one of the freshest rumors "“ Quicksilver will return in the MCU. And this will happen as soon as the Infinity War arrives. There are plenty of ways the character could cameo, but the most credible one is via visions.

The rumor says that Scarlet Witch will be given a taste of her own medicine once Thanos reaches Earth. As one of the most powerful Avengers, and one of the most unstable, the Mad Titan will want to take her out as soon as possible. And since she can’t control her emotions, what better way to incapacitate her than by messing with her mind?

As she did with the Avengers in Age of Ultron. I can see this happening, with Scarlet Witch losing her mind in the end (and revealing another great possibility).
