Ah. That smile. Wanda knew that smile because she'd used it so many times herself. She'd been using it all night and even as she unconsciously took a step back from it she felt her lips tug up into a nonchalant grin that did not reach her eyes.
"Yeah, it's really nice, it's-" she made the fatal mistake of glancing into his eyes then and she felt her smile crack and then she was frowning and chewing her lip as she finished, "been a tough week for everyone. So, a party's...nice." Wanda faltered; she looked away from him and towards the door and she wanted desperately to leave. She wanted to be home where she could crawl into bed and sleep for days, maybe with Pietro nearby for comfort. She needed more than anything for Tony to pull her to him and kiss her and tell her every thing was okay, that they were okay and that the Avengers would be okay without Cap. She wished he would stop smiling so mercilessly.
