Headscratchers / Wolf Creek

• Why does everyone (such as some on this wiki) assume Mick survived Eve's assault on him? Seemingly because you hear his snigger in the final scene of the first season, and then because there is a second season. Oh and Wolf Creek 3 (another movie) is coming out. But wait. Who's to say both the second season and the third movie aren't both chronologically prequels relative to the first season? Maybe he is indeed dead. Maybe the snigger just represents the enduring PTSD Eve is suffering after her ordeal. If this is a wrong presumption, then one would at least expect the new movie to explain how he survived his injuries (including being trapped inside a burning building).
