Fan Casting Nature is like That in The Unknown Howl

Susan, Tina, Forrest and Brian manage to reach a slightly brighter part of the local road, before seeing Unknown Howl stopping in the middle of the woods, watching them with his mouth still dirty with blood. [Tina] - Was it the lights? [Susan] - I don't know. I don't think so. The creature seems to show no more aggression, until it decides to turn back to the woods. [Tina] - I don't understand, why did he do that? [Forrest] - Unknown Howl is a predator, Tina, not exactly a monster. He didn't kill Brenda for any other reason. A while after that, the quartet starts to hear the sirens, which anticipate the arrival of the police.
