Who killed Y/N Stark?

Chapter 2 - Tape 1 Side A (Wanda)

"Let's start with the one and only Wanda Maximoff." The tape continues and Wanda breathes in deeply "You were good to me in the beginning. Then came your love for Vision and all of a sudden I wasn't needed. I admit I was a little bit jealous at first. But not as jealous as you became. We had fun while it lasted. But all good things come to an end."

"We shouldn't be doing this." Wanda breathes heavily as Y/N's hands roam freely around her body. 

"If it was wrong it wouldn't feel this right." Y/N smiles as her hands make her way to Wanda's hips.

"You're right." Wanda nods, pulling her in for a kiss. 

"I always am." Y/N smirks as her lips delicately place kisses across Wanda's stomach. 

"You know. It will always be you." Wanda smiles up at her.

"Don't make a promise you can't keep." Y/N shakes her head.

"I intend on keeping it." Wanda tells her as her hands grab Y/N's hips pulling her as close to herself as possible. Her gasp is silenced by Y/N's lips with a kiss as she pushes her own hips up.

"You never did keep your promise. Did you? And you turned into a very jealous person the moment you felt I was moving on." The tape continues.

"I know what you're doing, Y/N. It won't work. Should I tell her about us?" Wanda goes to step towards the door, but Y/N's arm shoots in front of her stopping her from taking another step.

"I am done playing your stupid games, Wanda." Y/N scowls at her.

"I'm not playing games." Wanda shakes her head.

"Then what are you doing?" Y/N asks.

"Do you love her?" Wanda turns to look Y/N in the eyes.

"I love you." Y/N tells her almost sounding frustrated.

"You must not know what love is." Wanda shakes her head keeping her eyes fixated on Y/N's.

"The reason for you being on these tapes is quite simple. You hurt me. And now I'm hurting you." The tape finishes. Wanda lets out a breath she didn't realise she was holding before turning to Vision who was avoiding her gaze.

"Vision, I..." Wanda begins.

"It doesn't matter." Vision doesn't look up.

"Can we move on?" Wanda frowns at Carol who was now fully controlling the tapes. 

"It's probably best." Carol nods pressing play.
