Since vampires are nocturnal, Mateo feels more comfortable at night than during the day. He's aware there's many large nocturnal predators, but he trusts his abilities enough that he's not particularly scared. Nervous, yes; concerned about what the Huntress wants to kill, yes; but not frightened.
So Mateo looks around his area and moves quickly and quietly off into the forest, keeping all his senses fine-tuned. If there's danger nearby, he'll either see it, hear it, or smell it- hopefully before it sees, hears or smells him.
