(POV : you are the Captain of your own squad)

You were with your squad, but left them to keep riding on their horses as you went in the air to kill a few titans. Levi sees you in the sky with your ODM gear, bringing down as many titans as you can. He rides faster on his horse, leading his team through the battlefield. But as he kept leading his squad, he hears something loud in the sky like an explosion. Smoke was in the air and you seem to be falling from the sky after getting hit.
