Barton finished firing at Klaue's henchmen. He saw the other team members on the ground, shocked by visions given to them by Wanda Maximoff.
He stood in silence for a moment, before turning around and shocking Maximoff as she tried to place him under the same power. As she fell struggling to the floor, he said "I've done the whole mind control thing. Not a fan.", briefly thinking back to his encounter with Loki three years before.
As he took the arrow from Wanda's head, her brother Pietro shoved him at full speed into a window. Pietro picked up his weakened sibling and took her outside.
When they were outside the ship, he said "are you okay? You good?"
She nodded, before seeing Dr Banner in the quinjet near the ship. Wanda looked to Pietro, who nodded as he said "go for it."
"Yes. Take care of the archer." Wanda said as she went to attack Banner. Pietro went back inside the ship looking for Barton.
The room was empty save for the other Avengers, who had been subdued by his sister's power. He said "I know you're in here, bird-face."
He listened silently for movements, before saying "or is it Owl-mouth?"
Barton hid in a dark area watching Pietro silently.
Barton readied an arrow to fire.
Pietro turned to catch the arrow that had been fired from behind him, looking up to face his attacker. To his surprise, Barton wasn't there, the arrow having been fired from an unmanned crossbow.
Pietro stared in confusion before a familiar bow had gone over his head and onto his neck, Barton pulling it backwards to choke Pietro.
As Pietro struggled, Barton whispered in his ear "oh, and by the way, it's Hawkeye, you quick little piece of shit!"
Pietro still struggled to free himself, eventually resorting to running around the room at mach speed with Barton's bow around his neck.
Barton used his bow to steer Pietro from side to side, causing him to crash into several doors and walls. Eventually, Pietro grabbed Barton and tried to throw him over a rail, Barton grabbing Pietro and causing him to fall as well.
As Barton and Pietro were both trying to get up, Barton recieved a call from Stark.
"Barton. Banner's in the city. Maximoff got through to him. Get the team over here!"
"No can do. Whole team's down. Just me."
"Shit. Okay, I'm calling in Veronica."
As Stark hung up, Pietro rushed head-first into Barton, causing him to go flying into midair before landing. A small piece of paper fell out of Barton's pocket as he landed. Pietro ran over to him and said "what is it with you and falling down."
Barton said "I don't like it when people talk down to me.", using his bow to trip Pietro over. As Barton stood up and dragged the other Avengers to the Quinjet, Pietro stood up and prepared to attack. He hesitated for a moment, before shrugging in annoyance and getting ready to leave. He stepped on something as he prepared to run, looking at his foot and seeing the small piece of paper that Barton had dropped. He turned and saw Barton leaving. He was about to shout to him to tell him about the paper, before stopping and shoving the picture in his pocket before going to find Wanda.
