Human emotions were baffling. He thought he considered Wanda a friend until just now, when he selfishly wished she'd stop smiling. Why didn't he want her to smile? He cared about her happiness, and in that moment she was happy, so why did it bother him that this time Captain Rogers was the one to make her laugh?
He watched through the reflection in the glass window as Steve helped Wanda into her jacket, his knuckles lightly brushing her arms. It was irrelevant whether or not this gesture was intentional. It hurt just the same.
Wanda called out to Vision as they headed towards the door. "We'll be back in a few hours, are you sure you don't want to come?"
He stared at the blank words in the book he was holding, pretending to read. Maybe he should go after all, but why be miserable all afternoon, watching her laugh at the Captain's bad jokes? He pretended turning the page, but did it too quickly and forcefully; a small ripping sound erupted as a tear appeared at the bottom of page 72.
"No, I'll just stay here. Tony might have something for me to do at the lab." He turned around to meet her gaze, forcing a smile.
"Oh, okay. Yeah, that's fine, too," she nodded and returned that same smile as she followed Steve out the door.
He turned back to the book as a soft click sounded behind him, letting him know the door had closed and she was gone. A swift movement of his wrist and the book slammed shut angrily, an exasperated sigh escaping his lips. He wanted her to be happy, but not with any other man than him.
