Rule #7: Mind your business.

A couple days after Noah found Tyler, they ran out of food completely.
They decided to split into two groups to find food faster and meet up back at camp before dark.
Gwen and Duncan were group leaders and Noah ended up in Duncans group. Right away, his team bolted into the forest to look.
Noah and Cody stuck together and talked about anything to get their minds off the killer, when he pointed out that it was getting dark.
Duncan ignored him and kept going.
They got into a heated argument about how they needed to get back but Duncan got so pissed that he left Noah in the woods alone. Cody shot him a sad look before Duncan pulled him away.
Noah sighed and sat down.
He knew he wouldnt make it back in time before the sun was completely gone so he just hid.
Sadly, his hiding spot wasn't perfect and the killer saw him.
It snuck up from behind and grabbed Noah by a rope, strangling him, and when he was about to lose consciousness, it stabbed him.
He winced and passed out.
The killer dragged Noahs unconscious, wounded, body towards the lake and drowned him, making sure he was dead.
In the morning, Cody and DJ walked around quietly, looking for Noah when DJ spotted him.
He gasped and ran towards the lake as Cody followed him confused.
Until he saw what he saw.

Chris, when going swimming, be wary of the humming coming from the lake.
It may be soothing, but dont listen to it, for it is hypnotizing you.
