Wicked’s ability to leave unhindered, without a super soldier appearing to block her path, was enviable. Wanda would have loved nothing more than to do the same, had tried to, but escape was something she obviously wasn’t allowed. Actually, she was sure they weren’t going to let her out of their sight until what they wanted finished was finished. So here she remained, tugging with more persistence at Clint’s arm and thinking that yes, in fact, he was only making things worse. This wasn't going to get her what she wanted, it wouldn’t help anything- not the people Cap and Tony were going on about or her brother locked away. Cap’s giving exactly what he got wasn’t especially surprising and if Clint wasn’t especially fazed by being shoved back, Wanda was still unprepared when that shove knocked him back into her, set her off balance and sent her stumbling back. She couldn’t say exactly what the catalyst was, but the snap of something inside that Wanda had been expecting finally came.
Maybe it was being talked down to, having others speak for her, saying how she felt and what she had to do as if she weren’t even there. Maybe it was this situation where everyone was wrong. Where Steve sounded so self righteous and Tony callous, Wicked reproachful and Clint choosing the wrong battle to fight and meanwhile they were just burning through what precious little time there was left. Most probably it was the shock of something physical that had finally broken through the numbness and left her glassy eyed and flushed in anger, barely hearing as Clint continued to yell at Cap, his glance back at her going unnoticed. A heat rose and spread through her, burning with acid that churned in the pit of her stomach and bile that rose in her throat as she gritted her teeth and made a small strangled hiss, the only warning before she shoved her own way between Steve and Clint. Her fingertips twitched, lit up with light, and she held up her hands in warning.
"Stop,” she snarled, "Or so help me God-" she left the threat hanging in the air, unfinished. They could decide for themselves what they thought she was capable of and whether provoking it was worth the risk. Wanda turning her gaze slowly between each of the Avengers. She would acquiesce, just to stop this from going any further, to move them all into action, to wait it out until she could find her moment and disappear.
Her voice was strained, her fury barely under control. "I'll do what needs to be done for these people but shut up. Just shut up, both of you! All of you! Stop wasting time and let's get this done.”
