Based on a prompt by flauermari on Tumblr: "i would love a scene like the one in batman the dark night in which the joker pushes rachel off the building and batman jumps after her ,i want something like that for oliver and felicity."
Oliver manages to fire the arrow straight into the bastard's chest, but it doesn't stop him from dropping Felicity off the edge of the building. His feet are in motion even before he hears her scream out his name and he goes flying off the edge after her without hesitation.
He reaches back and grabs an arrow, hoping his meticulous quiver arranging pays off because he won't have chance to fire another before they hit the ground. He takes as careful aim as he can in free-fall and releases the bow string. The arrow comes close to her, missing her my mere centimeters and flies past her toward the ground.
There's no time to see if it works because a moment later he catches up to her–the push off the side of the building when he first jumped giving him that extra momentum–and they wrap their arms around each other.
He manages to turn them so he takes the brunt of the impact and is glad to hit something soft and pillowy instead of concrete. Felicity lands on top of him, knocking the wind out of him and they bounce once before coming to rest.
"Oliver, Oliver, are you OK?" she asks, pushing up off of him to look into his face, her glasses lost sometime during the fall.
"I'm fine," he grinds out. She relaxes and rolls the rest of the way off him, rocking the giant cushion beneath them.
"I told you the 'airbag arrow' was a good idea," she says smugly.
He only sighs in response. He'll never hear the end of it now.
