"Perhaps I should introduce myself," Robert said. "My name is Robert Lupin, and I am, amongst other things, a healer and a potions maker. Remus Lupin was my brother, so I know a thing or two about werewolves, things that I can't image wanting to know otherwise. I think I might be able to help you. A couple of key questions, if you please. First, what did this dealer give you. You said you were bitten by your brother--obviously a werewolf, so did you know what he was, and was this your first time bitten?" Robert asked, suspecting that this man might not have been turned before now. He inspected the wound, already seeing that it was indeed a werewolf bite. Robert heard the sound of someone apparating in, and he glanced back to see Brian there with his bag.
"How did you apparate here?" Robert frowned. "Its too far for that."
"Portkey to Hogsmeade, and apparated from the square," Brian said with a cheeky smile, bringing the messenger bag to Robert. He had a potions vial in his hand already and he handed it to Robert. It was a vial of wolfsbane. Robert handed it to Jack.
"Take that for now," Robert said. "Let's keep any more transformation business from happening tonight, shall we? The moon will still be full enough that you might well have some symptoms tonight when it gets dark if you don't take this. Take it and then give me your facts, in order, as you remember them while I work on this bite wound."
"Would you rather I..." Khaat began to offer to rid Jack of the wound.
"No thank you, my dear," Robert said. "I've got this. I'll draw off some of the wound but these bites are resistant to healing, so we will have to keep after it for awhile. It will need to be cleaned and dressed properly, and it will need to be tended regularly because it will bleed and seep for awhile. It will need regular dressing changes. How about one of you take the blue glass jar in my bag and use it as an ointment on that wound and then dress it while I try to draw some of the toxicity off it, please?"
