Tony needed to see Wanda. He was frustrated, he was tired, he couldn't focus on anything Pepper tried to talk him through, and he was downright anxious about Bruce. He could barely even sit down and read six words before he was pacing again and asking for another cup of coffee, his brain on overdrive and his fingers buzzing to do something but unable to land. He could have gone home. If something happened, he could be back in under an hour. He could have at least been pacing in the garage with his cars and projects and hearing JARVIS' voice to talk through some of these things. It wasn't quite the same just humming in his head. He could at least work out some frustration with someone he didn't care to know and didn't stand a chance of fucking up in his own bed. But that would just put him further away from the issues and it would do nothing to help him stop feeling sick.
He could have been vibrating by the time he made it to the twins' front door. His knock was a frenetic drumming, abruptly ending for Tony to grip either side of the door and try not to claw his way out of his skin. That knot of tension that sat between his shoulders felt as deep as his heart, making it difficult to breathe never mind turn his head. He needed to fix something. He needed to see Wanda.
