George was never able to produce a Patronus after Fred died. I've read this a few times, and it still makes me want to cry, so I wrote this because you know...feels.
"Ex-Expecto Patronum!" He knew that charm, and the cry came easily to his lips, but all that came out of his wand was a thin whispering vapor.
The Dementor continued to edge closer, a deep rattling breath sucking away any air, and leaving him with a phantom.
"Expecto-" they were in the Room of Requirements, and Fred had just made a coyote appear from the end of his wand. George scowled good-naturedly at him, and after only two more attempts, he to made his guardian animal appear, but it happened to be a raven. The two animals gambled about the room, chasing each other playfully.
"Expecto Pa-" the Dementor swiped away the pitiful defense, a cold lifeless hand reaching towards his face, intending to end his life, and he welcomed it.
"Expecto Patronum!"
A silver bright Ostrich came storming onto the scene, waving its feather's around threateningly, and brandishing away the creature.
"George, George! Look at me!"
He blinked several times, noting that it wasn't the one he wanted to see, but a love of his none the less. Angelina was bent over him, concern etched into her every line as she continued to demand if he was okay.
"I, I saw-" then he sobbed. The memory of his brother, the clearest and most defined thing he'd had to cling to in a long time, and he'd welcomed the chance of death just for that lasting moment. His wife said nothing, wrapping her arms tight around him, promising never to let go.
