For the briefest of moments Viktor thinks perhaps they can make a clean break, which isn't a matter he even lets settle before that horrific sound makes him grit his teeth, molars buzzing in a gentle ache.

Still it's enough to stumble into the jutting rocks, through and into the mouth of one of the caves he's never explored for a variety of reasons, self preservation being one of them. Gods knew what lived in the caves of the Trench, and so close to the sea, but it's still a relief to only hear the faintest call of the creature, nearly buried by the wet thump of his cane on slick rock face.

The man he's barely had time to register beyond 'new sleeper' offers a hand and Viktor only regards it a single, hesitant moment before taking it, grateful for the help to get beyond. He stays quiet when they can finally settle, back resting against the damp wall.

"Seems it must be deaf," he murmurs, quiet regardless of the fact of the echolocation, now that he had the chance to assess the encounter. "I suppose being still may work more in our favor than being quiet."
