Red Vision (MAJOR EDITING)
Wanda Maximoff has lived her entire life with her brother, Pietro. Now, with her twin dead, Wanda has to figure out how to survive. She's a wreck--- everything she does, she can imagine Pietro doing it, or saying things, or merely his expression, and she'll break down. She's grown close to the Avengers in the month since the battle with Ultron, the evil AI. Clint and Natasha almost seem like parents to her--- really weapon obsessed ninja parents. She's got a lot in common with Steve and Thor, who have both lost brothers. And there's Vision to deal with--- he's the one helping her through this the most.
The nightmares begin--- Wanda's vision goes completely red, shadows reaching for her. Her powers are unstable and she is liable to injure others when distraught. There's something wrong with the silver ribbon she's vowed to wear until she can let Pietro go, until she can stop asking for him back. It seems to ward of the nightmares--- until the nightmares become very, very real.
Pietro has returned, a shadow version that only she can see. He claims to be real, but when he thinks she isn't watching, his face changes into something that is NOT her brother. Pietro begins to hunt the Avengers and tear them apart, and Wanda must have the courage to do the unthinkable.
