"Hold his mouth shut," Hemingway said darkly as he returned, glancing up at Sirius. His face conveyed his seriousness, though the other man still objected.
"What? Why would I do that? He's hardly breathing as is," Sirius barked, oblivious to his own bleeding and the deep cuts and scrapes on his own body. Remus was his concern, and he shot Hemingway a glare.
Glaring back, Hemingway reached over and took Sirius hand, slapping it over Remus' mouth. Before the other could object further or complain, he jabbed his finger down into the cut on Remus' neck, feeling around.
"Good, we're in luck! It's not too deep, I don't think she did anything we can't easily reverse with time," he explained, glancing back at Sirius. "And did you want to hear him scream when I did that? No, you didn't. It's a deep gash, but not deep enough."
Getting to his feet, he wiped his finger off on his robes and hurried to the shelves, picking through everything. He grabbed a bottle of dried leaves labeled Echinacea, gathering up some oils, two bottles of blood replenishing potion, and plaintain leaves and antiseptic for the burns. He hurried back over, working quickly and mashing up the Enchinacea leaves in his pestle, mashing it with the oils to make a paste.
"Hand back over his mouth, Sirius. This isn't going to feel pleasant, but it'll keep the poison from spreading into his blood stream."
Once Sirius did as he was told, Hemingway dipped his fingers into the mixture and started pressing it back into the wounds. He knew it was gruesome, but being a Potions Master did not make him a healer, and he had little to work with other than his knowledge.
Turning his head, Sirius gagged a little but kept his hand over Remus mouth, the other petting his hair. "It's okay, Moony. You're gonna be okay."
