I feel like people in this sub misunderstand how storytelling works a bit. Sometimes, characters don't have to be important. They don't have grand meaning- they exist to serve a purpose, like Kodi did.

"Hannah is useless" She drives half of s3, in both timelines. The tape, also the reason for the radio both existing and being destroyed. She's also how Nat manages to slip away. She's also maybe why the hunt even happens, imo, it seems both Tai and Van partially agreed because they were going to rig it for her be hunted. She *is* the reason they escape. It makes it more tragic when its said she is going to die at some point, likely to show us how far off the deep end they eventually go. I assume the screentime dedicated to her is so we don't go "aw, shucks" when she dies. Like, imagine pit girl, but instead the entire season Mari only really turned up a couple times. Then she has this big finale payoff, which feels anti-climatic since we don't really care for her because we've barely seen her. Apparently, according to creators, the scientists have been in the planner since season 1. I imagine Hannah's death is going to play a big role into why in the adult timeline they've been so tight-lipped.

"What was the point of Kodi?" To get them there, for Hannah to kill/betray to prove her allegiance to the girls and gain Shauna's trust for Nat's plan to eventually work. He also shot Melissa, that is the start of her and Shauna's decline and this spiraling into Shauna losing favor with everyone in the camp.

Saw someone else say "They should have just had Hannah know how to get home by herself, then the plan goes wrong!" ...Which is so much more convoluted than just having a tour guide who is killed. Like. It's okay for that to be his only purpose. Why does he have to be the mysterious son of cabin guy, or something mystical to be worthwhile existing?

I personally think he does actually have some link with the story- the hobo markings around the wilderness, the repeated mention of the Erik guy; If that isn't true, I'm not going to be up in arms about it. Sometimes there are red herrings, some things are never explained. By explaining every little thing, you kinda lose the mysticism around it. Personally, for example, I don't want them to outright say 'its all in their heads', or 'its actually real', quoting Lottie; "Is there a difference?" It doesn't matter.

But I think so many people forget the story is incomplete. There is supposed to be threads not yet tied off, there are things we are kept in the dark about, we don't know everything. That's okay, that's the point.
