Voloke looks at Serge with a raised eyebrow as the large man spoke to Elle's rat, asking it if it knew of or could gather information relevant to the investigation. Rather than shake his head though, he just looked ahead to the direction they were walking in. "So... if Luth was a person not too long ago... exactly what to Wights do to a someone to make them into another Wight?" He asked. Voloke's tone was one of genuine curiosity, rather then the fear that a normal person might show. He had proven to himself that he could kill them, and if he could kill the Wights, then they were on, at worst, even terms. Now he simply wanted to know what it was exactly that they did with their victims. Better to know what to look out for than not. He figured that Ghaazala would probably know the answer, but didn't speak only to her, and rather spoke loud enough that everyone present would hear him, in case someone else had more knowledge of the creatures.
