Donahue... Donahue... it wasn't ringing a bell. No matter, Aaron would figure out who he was, and see if he could be of any use to them. From his tiny interaction with him, he did not seem to be one way or the other when it came to good vs evil. Though, Aaron suspected, he did not just "accidentally" throw the piece of burning wood on top of his wand.
"Wands do go through a regular wear and tear process. Wands can get a little rusty and a tune up from a professional is never a bad thing." Aaron smiled slightly, realizing he was trying to sell his business while flames where burning Diagon Alley to the ground. "But I digress, now is not the best time to be discussing these matters."
Aaron casually strolled over to the board that was flaming and over top of his wand. Luckily for Aaron he knew better than to leave his wand unenchanted. Dueling could result in some pretty harsh damage on a wand and if it was not protected it would be destroyed, much like it would have been if he had not made it fire resistant. He reached down, grabbed the board quickly, and flipped it over so that his wand was visible. He picked it up, rubbed it on his pant leg, and inspected it making sure it was fine. "Fireproof."
He smirked and he walked past Donahue, gave him a large slap on the shoulder, and began to job off in the direction of all the commotion. "Thanks again, Donahue. Oh, and its Marcheti's wands." He turned and left and made his way towards the other people in the alley.
As he was running, he heard a scream, and he stopped in his tracks. Someone was trapped inside of a building. This was his chance to go from local wandmaker to hero. He sprinted at the building and figured out his best chance of entry. "Reducto!" He shouted, which was followed by the front door of the building being blasted inwards. "Aguamenti!" Water poured from his wand and cleared a path to the room which harbored two people, an older woman and here child. The woman was in tears and hovering over the child, who was unconscious. Aaron scooped the child up and ran back to the entrance, the woman in tow.
"I need a healer!" Aaron shouted as he ran from inside of the burning building. He was not an exceptional healer, though he wished he was, and he would certainly need the help of someone else. He was not sure if the boy was alive or dead.
