Don ' t listen to people in YouTube comments <| sep |> On the other other hand , the MM not asking for donations now makes a lot of sense from a ruthless strategic perspective . Their Grounder supply is gone , and they can ' t send out the Reapers to collect more Grounders without breaking the deal with Lexa . We ' re never given any numbers on just how many blood treatments they need , but the implication is that they don ' t have much time left . Which means that getting bone marrow for everyone in time without killing anyone would require the cooperation of the Arkers outside of Mount Weather , and whatever Kane says people who are about to die will say anything , that would be a pretty hard sell . The only real alternative would be to use the captured Arkers for blood treatments to give the MM the time to figure out another solution . But at least some of them would probably end up dying from that anyway , and it would make negotiations pretty much impossible , so why bother ? That being said , On the other hand , maybe the inability to cut a deal when it absolutely should have been possible makes the whole situation more tragic . I agree , and I think that it would have been better to include a justification earlier for why Cage wasn ' t willing to consider a nonlethal option . It actually isn ' t hard to think of one even sticking with the bone marrow concept . Mount Weather has put a lot of effort into scaring the Grounders away from using guns and presumably other technologies so that the Reapers can do their job , so a technological civilization landing on MW ' s doorstep should logically be a pretty huge wrench in the plan . All they had to do was include a conversation between Emerson and Cage about the situation in Camp Jaha . Cage This is bad . There are two ways that this can end . Either the Arkers share their technology with the outsiders or the outsiders wipe out the Arkers and steal their technology . Either way , things are about to get a lot harder for the Reapers . The guns are bad enough , but if they figure out how to make their own tone generators , we ' re finished . Emerson Sir , I think we should consider using a missile . Cage That might buy us some time , but it wouldn ' t destroy everything . In any case , my father has adamantly refused to use missiles against the Ark . Something about how crashing a ship carrying soldiers is one thing , but wiping out an entire civilization is quite another . Then when Tsing presents the option of using bone marrow to Cage Tsing To be on the safe side and limit side effects , we ' d want to take no more than one donation every six weeks . Seven of the kids have volunteered for blood treatments . If all of them are willing to donate marrow , then we ' ll be able to make everyone immune within 7 years . Cage With what ' s going on outside , we definitely don ' t have 7 years . We might not even have 7 months . How fast could we get enough marrow for all of our people , if we didn ' t bother asking ? Tsing There are 382 of us , that ' s roughly 8 procedures for each of the kids . We could carry it out in less than 3 weeks , but every one of the 47 would die . Scene continues as in CanonThis ties into another complaint I have , which I ' ll discuss more fully in another comment the tendency of characters on this show to not even bother discussing alternative courses of action , and instead just barrel ahead with whatever the script says that they ' re going to do . The last time I can remember an actual discussion happening is in episodes 7 and 8 , where they debated between Jaha ' s plan of leaving for the City of Light and the alternative of staying and fighting . But since then , we ' ve had major decisions like the TonDC bombing , Lexa ' s deal with the Mountain Men , and the final decision to irradiate Level 5 where alternatives either aren ' t discussed , or are simply handwaved away . What has ended up happening with each of these instances is that the writers have posted justifications for them on social media . In my mind , if an explanation is necessary for a significant portion of the audience to follow a story , then the explanation should be in the story itself . After all , the vast majority of the audience is never going to check out the writers ' social media accounts . This is something that only gets worse in Season 3 , which I ' ll discuss when we get to the episodes in question . Also , I think that the story would just plain be better if Kane hadn ' t ended up in MW in the first place , for reasons I ' ll get into in another comment , but it would help this point out quite a bit if it was just one of the kids or maybe Wick who was presenting the idea of donating bone marrow , rather than the Arker leadership .
