Tony hadn't even taken a breath before he found himself stumbling back in cold sand, the sky behind him gold now and making the face of the hotel glow before Tony blinked, and suddenly it split and shattered. How could someone who had called themselves an Avenger do that? How could Tony have allowed him to? Why didn't he stop it? Why did he just let Quicksilver go like that? Before the hotel had finished its collapse, the boom of the explosion still reverberating across the beach, Tony launched himself at Quicksilver, former Avenger, terrorist, murderer, turncoat, liar, with enough force to knock him to the ground, grabbing for his hair, ready to tear him apart, choke the life out of him, stop his heart for just long enough for him to know what it felt like before the police and paramedics arrived to strap him down so someone else could get their hits in. Maybe Wanda-- Wanda deserved some vengeance for his treachery. Maybe all the people and their families that were still in or just too close to that building as it came down. Maybe all the people who's lives had to stop for the clean up and the rebuild-- if they even could rebuild-- because Quicksilver wanted to show his daddy what a good boy he was, an empty message to the rest of the world, just innocents suffering for being at the wrong place at the wrong time. Just because they welcomed Tony Stark into their hotel. And how dare you, how dare you make me so fucking angry you evil fuck.
Tony couldn't even think of how strange Pietro was acting, that he still didn't have answers, that none of this made any sense. He needed to destroy him.
