Tears form in Zaana's eyes from the intense pain - perhaps tail-first would have been a more competent choice. Despite this, she simply carries on, working through the pain that forms all over her mouth. Her venom drips down steadily from the wound in her upper maw, although fortunately it won't affect her, and it doesn't work via ingestion anyway, it would be too warm to take effect by the time it was absorbed. The liquid is very cold to the touch, even freezing in places of concentration on Thanatos's scales. She forcefully yanks his head into her throat, "accidentally" scraping through a layer of his scales with her fangs as he is dragged inside, and her throat muscles clamp down far harder than was necessary.
