Severus was so busy attempting to purge his mind of all emotion that he nearly missed what she was saying.
The sound of her voice had set his heart pounding alarmingly fast, and he felt as though his throat was being constricted. He was sure that, if he spoke, his voice would be nothing but a hoarse croak.
In an effort to centre himself, he wrapped one hand around the opposite wrist, pressing a finger against the pulse point there and all but losing himself in the feel of the rapid thrumming. He breathed in deeply but quietly, not wanting her to notice that there was anything out of the ordinary about his behaviour but also hoping to slow his frantic heartbeat.
He had almost managed to return to stasis when she spoke again, her words raising the same sense of near-panic in him. It was no use; he was not going to be able to master his emotions. Not when she was here.
But then, he didn't really need to fully regain control. Yes, these feelings were unpleasant, and yes, it was difficult enough talking to his old friend without such intense anxiety to contend with, but it was hardly as though she would be employing Legilimency against him. He couldn't clear his mind, but he could at least suppress his feelings enough to carry out a seemingly normal conversation.
"Miss Jones informed me several days ago about the shortage of Murtlap Essence," he said, frowning. "But I was unaware that supplies of Dittany had fallen so low."
He took a moment to consider the problem, cursing the fact that they had run through their stock so quickly. He had told them to attempt to conserve those precious ingredients as much as possible, that he couldn't guarantee when he would be able to find more, and that Dittany in particular should only be used when absolutely necessary.Â
"I have parted with as much of my personal supply of Dittany as I feel comfortable giving away," he said, gesturing idly at the shelves of jars and phials that now made up his 'stockroom'. "I have reserved a small amount for emergency situations, but apart from that I have given all that I have."Â He frowned. "The Murtlap Essence is less of a problem - I need only take a trip to the seaside and I can replenish our supplies, but Dittany is not native to England. It will be difficult to obtain more - impossible, even, without venturing into private homes, or else finding a way to make it grow here."Â
He raised an eyebrow questioningly. "I'm afraid I have allowed myself to become rather isolated these past few months. Is there anybody left alive with that sort of Herbology expertise?"
