okay so i have a theory about how akilah (and possibly many more) is going to die! i wasn't going to mention it till i had more proof but i've connected some dots. current working name is the Bite Theory because "everything with teeth bites" :)
obviously, spoilers for s3 ahead, be warned!
i think the yellowjackets are going to get rabies. at the very least akilah! theres a couple things that make me think this, the main being what we saw in her hallucination in episode 3. we're told by the talking llama that "everything with teeth bites", which while it could mean a variety of things i think its probably a very literal meaning in akilahs case. her whole thing this season (and a large part of season 2) revolves around caring for animals. wild animals. and its fairly likely that that the reality that the yellowjackets have shown is not accurate to what is really happenong (yellow filter theory), so i think theres one of two ways that the Bite Theory could happen.
1.) and the most straightforward, akilah is bitten by one of the animals shes caring for or an animal she comes across in the wilderness. possibly in the caves since it's likely that a fair amount of season 3 is going to revolve around them. this could also be what her sinking into the dirt in her hallucination could mean. the wilderness is taking her, like the way it took laura lee and javi, into it and under it. further evidence supporting this theory is how weird all the animals are in the wilderness. the suddenly dead birds, the sick bear, even the wolves were strange because wolves generally do not go out of their way to attack humans, especially not humans in groups (from my understanding). while this may be due to some other phenomenon occurring out in the wilderness (possibly due to heavy metal poisoning) we at the very least know that the animals out in the wilderness are NOT normal.
as for the 2nd way the Bite Theory could occur, its a little more out there, but personally my favorite and i think would work well with the girls further descent into the wilderness:
2.) and, the more outlandish, is akilah being infected by coach ben or mari. akilah has shown herself to be a very compassionate character, especially within season 3, and i think thats going to get her killed. from what we know currently of the final survivors, its reasonably safe to say the neither akilah or ben are likely to make it through the final winter. we also know that pit girl is probably either gen or mari, however, with the "It Girl" episode the general consensus is that its probably gen, and the "It Girl" episode is a misdirect. so, mari probably died before the final winter. we have also directly been shown mari AND ben consuming bats (gross), which as i mentioned in my previous theory, are EXTREMELY well known carriers of rabies. and we already know that all of the wilderness animals are NOT well. rabies can also be contracted through eating an infected animal, so even if neither of them were bitten during their time in the cave its still possible for them to contract the virus. ben has also been living in these caves for MONTHS and exposed to bats and likely other rodents the entire time. we also know he's not well because mari hears him talking to "something", so maybe it was because of the gas in the caves or maybe he's already sick and losing his mind.
so assuming either ben or mari (if not both) are infected at the current point, how would akilah be infected? if its ben i think it will be dependent on his outcome during the trial. if hes found guilty i think he'll try and escape and end up attacking and biting akilah during the process. if he's found not guilty (or held prisoner) he'll get gradually sicker and akilah will try and help him, maybe by bringing him berries, hm? if its mari that bites akilah i think it will happen at the end of the season or after a timeskip. mari is clearly a more important character this season, so i imagine her death will be fairly dramatic. i could see her getting extremely sick and lashing out in a fit and biting akilah.
also another thing to note is that literally in the 1st episode of season 3 we see mari get bitten by shauna!!!! which considering how symbolic yellowjackets is could totally mean something since "everything with teeth bites" seems like its going to be an important theme this season.
another reason i think this theory holds weight is because i don't see ben NOT being eaten when he dies. they hate him and as much as the girls claim to "not being doing that anymore" i really don't see them wasting that much food. they've been willing to eat people and they will again, so i think they'd need a better reason than morals to stop them now. same with akilah and mari, i think depending on how close to winter they die they'd be willing to eat them even tho they care a lot more about them than ben. unless they cant, in which case they'd either burn or bury (cough cough like in akilahs hallucination cough cough) them. also shauna straight up says she wishes they'd eaten mari first so.... definitely not gonna be morals that stop her.
we also know they literally do go back to cannibalism at least by winter. why? well, it could be because they have run out of food, but if they know how hard winter is wouldn't they have prepared better? unless they can no longer trust their food to be safe.
anyway thats a lot to read so tl:dr: theory goes, akilah gets bit by either a.) animal b.) coach ben, or c.) mari and contracts rabies, dies and results in the girls going back to cannibalism.
maybe im totally off base here idk but this was fun to think about! sorry this got really long and i think i even missed a few things to say, but thanks if you read this far! (also if anyone agrees or has more to add pls let let me know!)
