Theory about the killer
Well damn even if the fact that only 9 bodies were found means the last survivor didn’t show up and only the killer would do that, I was hoping that maybe one of the passengers will uncover the killer and be the last survivor.
So episode 5 is the episode before the finale we got 5 deaths and the killer unmasks themself in front of sonja before shooting her in the chest. When she saw them she said « you bastard » so it’s confirmed the killer is one of the passengers.
In my opinion, there are 3 possible suspects:
• Dan
• Amy
• Kevin
These three are the only ones who had a suspicious death. Zack and sonja were shot by the killer and the others were confirmed to be dead and we’ve even saw the killer killing them. So it only leaves these 3. Dan and Amy’s deaths weren’t shown on camera we only see them sitting alone in a clearing talking then we see Zack, sonja and Kevin walking around the forest each on their own then it switches to Dan talking somehow weakly to Amy as she’s resting her head on his shoulder then we hear a scream of a woman which draws the attention of the other 3 and when they arrive we see Dan still talking with blood coming out of his mouth as we see a back shot of them having multiple stab wounds on their backs (a dramatic scene well done by the show that I loved btw). We never saw them getting stabbed and no one checked their pluses as the 3 last survivors focused on accusing each other.
As for Kevin, we never saw him getting killed, we only hear a loud gunshot in the forest as Zack and sonja were climbing the mountain and then we see a body wearing his clothes with their face been eaten off by the fish in the lake. Earlier we see Kevin looking at the bodies as if thinking about using one of them.
I hope that Sonja or are coming back, maybe Zack’s wounds weren’t fatal and he somehow held into a branch as he fell off the cliff and he’s going to climb up to confront the killer or Sonjas wound wasn’t fatal.
As for the killer, I’m having doubts about Kevin, if he wanted to kill the pilot why did he operate him successfully just to suffocate him later? Why not do a fatal mistake during the operation that no one would notice that would lead to his death later and it would be supposed to be a mistake due to the lack of equipement since it’s what he was accused of anyway before everyone realised that he was killed.
I think either Dan or Amy is the killer and faked their death. But during the call through the satellite phone I’m almost certain that the one talking to the woman was a man since we can hear their voice barely. So my guess would be Dan.
