You're Wanda's boyfriend.

You and Wanda are best friends, but she's really in love with you and knows you're in love with her too, so she decided to make you jealous so you'd make the first move.

You were at a party at Avengers Tower and you see her getting a little too close to Vision, then they start dancing... And then they go off to who knows where.

Of course, this was all Wanda's plan. An hour later, she returns and approaches you.

"Want something to drink?" she asks, smiling innocently; she knows you, too, saw everything that happened to Vision.
