Without the magic barrier bearing down on him, Tony was so sure it would be easier to breathe. While it slid over him, though, his last breath caught in his chest and he squinted his eyes against whatever awful thing was going to happen next, only to be left standing free in the vast expanse of this alien desert. He couldn't go fast enough, throwing up more sand into the storm as he launched into the sky, every breath still clicking and wheezing in his throat until he was circling studiously around the one curiosity on this barren landscape; nothing else unearthed or revealed in the sandstorm that he could see raging hard on the horizon.
That was what that whole performance was about-- Iron Man quitting the team? Sorry, abandoning, because they couldn't handle it on their own. And yet, they were just as capable, just like he said when he left them, just like he thought when he expressed his respect for the Fantastic Four, the Heroes for Hire, even the X-Men despite the mess they liked to stew in. That was a whole lot of people taking responsibility for the world. Tony didn't realize leaving them to focus on the people that were far more dependent on him meant the Avengers had to disband, which made him sound very fucking important. He had never fucking told Wanda a goddamn thing; she and the rest of them had shown him that his way wasn't welcome. She was telling him how he 'ought to act', so what the fuck was making him the villain here?
The building was a perfect pyramid, or would have been without the wear of the sand, with only one obvious point of interest on its surface. Set slightly into its face, where Iron Man could land on a lip of stone, was a darker, 8x8 brick, appearing dense as it was wide. And it was quiet, suddenly, sheltered from the wind, letting Tony think for a second with both hands on his one entranceway. Depending on anyone lost him his company, got him shot in the back, got people killed; Wanda had yet to prove she was any better than that. Demanding that he be this kind of friend to her without ever doing anything to earn it only made his body ache, exhausted with the heavy lifting he obviously wasn't doing enough of. She never asked him to help her, either. Iron Man pushed, the brick sliding slowly and gently across the smooth stone, inch by inch, until click. It stopped, and slowly sank into the floor.
