Finnegan had been quite startled when he found himself being addressed by Ludo. In fact, his astonishment was quite plain, as he visibly jumped in his seat, a strand of Dittany root dislodging itself from his hair and landing on the table. Finnegan grabbed the strand and hastily stuffed it in his pocket, lest Ronan get onto him for dirtying the place up. Then, the addled Potions Master gathered his wits about him to realized what was said. [color=gray]"Dragon Blood and Doxy Venom yeh say? Good, I've been outta Doxy Venom fer 'bout a week now. As fer Dragon Blood, I've got a bit left, but I'll take what I kin get. After all, that's becoming rare with Voldemort thievin' all the Dragons away."[/color] he said, his voice coming across as one who was in full possession of his mental faculties.

However, Finnegan missed Siobhan's entrance, as she came in right at the comment of Voldemort's dragon-nappings. As soon as Finnegan realized what he'd done, he shot her an apologetic look. He nodded to the other ashes, before turning to Ludovic. [color=gray]"I'll be by after the meetin' to pick it up. Will that work fer yeh?"[/color] he asked. He was more trusting of the former Snatcher than many would be. After all, he (somehow) managed to keep his Potion stores up. Finnegan himself went out to get his ingredients when he could, but the other Mediwitch (who he absently noted was still absent) had known him from St. Mungo's and didn't let him stray to far, lest he have another catatonic episode. However, the voice in his head reminded him that Voldemort might have died, and he resumed his (to the others) slightly crazed grin. 

However, when Viktor Apparated (a skill Finn was jealous of, as he had no talent for it whatsoever) and began talking about Horcruxes, Finn's countenance became quite serious once again. Horcruxes were very dark magic, indeed. Even though he still had the appearance of a homeless person, everyone present could tell that Finn was having a rare moment of being in his right mind (outside of when he worked on any sort of Potion, of course).
