Start over? From when, before she took off without warning? Before Pietro did the same thing? Before they all went to the West coast and became 'Clint's team'? Tony wasn't getting how far back he was supposed to go to boot safely and make everything run cleanly, and he definitely wasn't seeing how that was supposed to help Wanda. She knew she was wrong, great, she held her brother's hand for two days and thought she could swallow her pride enough to say the words. That bullshit was only step one, and trying to guilt the 'people who care about you' was definitely not step two. Forgetting about was a giant leap backwards.
"You don't get to fuck up then just ask for a clean slate," was a lot more concise, though saying it out loud made Tony suspect there was an exception to the rule here. Maybe normal people didn't, but the Scarlet Witch got anything she wanted with a little pyrotechnics. Maybe that was why she could go into something knowing she was wrong and come out of it with a little 'I'm sorry, please?'. "You don't get to blame someone else if you know your excuses don't hold up," sounded stronger, but Wanda was pretty right about that one; Tony didn't want to hear any of the reasons if she couldn't be bothered to dream them up. She fucked up, and she didn't even have the conviction to stand by her decisions. He hugged Anthony in both arms, bringing him higher on his chest like he meant to close himself off from the rest of this conversation.
