The deck swarmed with evacuation ready agents as the Avengers appeared, prepared to lay cover or back-up or run distraction, whatever would help get the helicarrier out of Magneto's hold and into safety. Only their best bet was immediately struck down as the Scarlet Witch's powers stuttered, sending them falling and knocking down the unprepared agents like dominoes. There was no other back-up plan for total removal of engines, and they were only still here on a prayer already. Sitwell froze, flinging out his arms to keep his unit behind him as Magneto brutalized their last hope, and searched the faces of the Avengers for the next likely command. Where was Captain America? Who was in charge here?
He didn't even make eye contact with the Wasp, who had turned her back and disappeared over the edge of the ship before Sitwell's team had recovered. He shouted over the noise, "Eyes on Hawkeye!," to them before sliding across the trembling deck and skidding to a precarious halt at the tortured side of the helicarrier. She was huge! She could do that? "That's not on record!" he complained, voice too small under the wind and the metallic groans for the Wasp, Giant-Woman, whatever she was to even hear, not to mention the flash and bang that hit her ear. Sitwell flinched back, eyes squeezed shut against the flare then forced open to check her status: back-up plan B terminated. "Hey!" he protested, too many surprises in a row when she was just gone after being so giant and didn't even think before standing, taking a run and diving off of the helicarrier.
He shot through the smoke of the explosions with his arms tight to his sides, trying to keep watch through the force of the wind and the choke of the debris and spotted her-- tiny, dead weight. Sitwell tried to squeeze tighter and rocket his jump after her, closing the gap too slowly, the water coming too quickly, the fall high and fast enough to shatter them both on impact. But he gained on her, reached and grabbed her arm and flipped to put his back to the water and hold her against his chest when he pulled his readied evac chute. Sitwell's stomach hit the water and his heart the sky, and when he had enough breath gave a high, hysterical laugh and muttered, "Good jump."
