i do think it's interesting that in willow's ritual to resurrect buffy it's specifically a snake that she coughs up. like there aren't that many snakes in the series it's pretty much the giant snake monster in "reptile boy," the mayor in "graduation day" and the snake glory uses in "shadow" and it feels interesting that all of those snakes are about the pursuit of something for selfish reasons — "reptile boy" is literally about sacrificing the lives of girls so that rich, powerful men can get and stay rich and powerful; the mayor's ascension in "graduation day" similarly is about power, is about consolidating power, and also involves the sacrificing of a young girl, faith. and like, buffy is the one who stabbed faith, but in terms of the violence done, the mayor was the one using faith to further his goals. he loved her in his way, but still at the end of the day her strength and ability coupled with her destabilized sense of self were fodder for his political ambitions, and he sent her to kill angel knowing full well the danger she could be in. "shadow" is about glory trying to find the key so she can destroy everything in existence just to go home, and even though she doesn't know it's dawn at that point, it's still once again a young, vulnerable girl being implicated, losing her life.
and then you have "bargaining," willow coughing up a snake, in this sort of reversal of "reptile boy" and "shadow," where the snake is this external thing you're feeding to attain a goal. it's much closer to "graduation day," where the snake erupts from within the mayor and consumes him.
and that's interesting when you consider the role of faith for the mayor, the role of buffy for willow. that's the chink in the mayor's snakeskin. the other cases of young girls in snake episodes are very straightforward attempted sacrifices for power. but there's something curious about the fact that for willow and the mayor, the young girls they care about really were stabbed, really did die, and that it wasn't an intentional sacrifice to a snake. rather, it contributed to the swell of desire for power and protection and invulnerability that makes willow's snake and the mayor's snake live inside them, rather than an outer force that they feed.
for the mayor, faith is at the heart of why he wants that power to begin with. the mayor is "a family man" without a family. he's the sort of guy who would say he does what he does "for the children," and faith is that. faith is his adoptive child. he had this plan before her, but it means more now, it's more vulnerable now, he wants to protect her. he genuinely thinks, as you can see in "this year's girl," that without him there is nothing for her. you can hear the emotion and ache in his voice when he says "some people who should be here today aren't." wanting faith's safety is a massive contributor to his feelings towards the ascension and amassing as the season progresses, and yet he is the one who sacrifices her. he sends her on the mission to kill angel which ultimately leads to her coma. the way him becoming the snake is linked to this sacrifice of an innocent life.
and willow is so similar. she didn't cause buffy's death. but her snake arises in this undeath, her snake appears when she traumatically rips buffy from death, in a sense sacrificing buffy in reverse. sacrificing buffy's peace in heaven so buffy can continue to fight against evil, because willow needs her. while willow's stated goal isn't greater power and influence, that's definitely a part of it. i read willow in "bargaining" and beyond as being in deep denial — she really thinks she's not a bad guy, not a bad person, that her aims are pure. and i do think she really Believes buffy is in a hell dimension. but, at the same time, she's been anointed the boss of the group in buffy's stead. she's living buffy's role, by being the programmer of the buffybot, the bot becomes this extension of willow. and there's this curious dichotomy where resurrecting buffy is both this event that gives her tremendous power — she's one of the most powerful witches in the world at this point — and also this attempt to get rid of that power. she doesn't want to be the leader of the group. she's off-kilter. she desperately wants buffy back, so that buffy can take her rightful place as the glue of the scoobies. but buffy comes back fragmented and traumatized and not in a place to be anyone's hero, she's just trying to remember how to be a person again, and the fact that willow's power play to fix everything didn't work if anything only fuels her power spiral. she keeps trying to fix things with magic and intimidation and forcing her will, over and over again, for the rest of the season, so that she can be so powerful that she doesn't have to feel this way, this destabilization, ever again.
and you can honestly read those other snake moments as about destabilization and vulnerability as well. the frat bros in "reptile boy" live and die by hierarchy — they sacrifice people at the bottom of that hierarchy so they can stay at the top, and their position on the top is so fragile, however it might appear. the mayor is deeply afraid of being vulnerable as well — literally he taunts others about how he is "invulnerable," verbatim. he's immortal and unchanging and represents old guard values that are crumbling. the world is trying to eat the things that he holds dear — patriarchy, order, law — so he needs to eat them first. and glory too, is so vulnerable, is in this human form that can be killed at any moment when she used to be the most power being in the world. she doesn't know who she is on earth, she is constantly being destabilized by the shame and desire and feeling that creeps in when you have physical human form, and she wants to go home so she can be bigger than those feelings, squash them like bugs.
i find it so interesting with willow's snake that it's coming from within her, and she's vomiting it up. the desire for power, the fear of vulnerability, the willingness to sacrifice the lives of young girls specifically, that's within her, and she is trying to eject it, compared to the other cases, where they are literally feeding or trying to fully embody that snake. but vomiting the snake doesn't save her from it, because it came from within her. she never acknowledges her link to the snake, and so it keeps pursuing her. it doesn't feel like coincidence that the effigy of proserpexa is wrapped in a snake, and has a snake tongue:
willow's desire for power, for specifically invulnerability — to have protective snakeskin wrapped around her, to have the power to swallow things whole, a power you need when you are so aware of your own vulnerability because you are constantly slithering on the ground — follows her. she can't protect herself from the world, no matter how powerful she gets, and so she decides the only way is to destroy the world.
there's something haunting about that, about the fact that willow is in the world. willow in "grave" is making a suicide attempt, this dark mirror of buffy's self-sacrifice in "the gift". which can also be read as a suicide, as buffy's death wish and depression catching up to her. there's something about willow, buffy's spirit, as per "primeval" feeling SO destabilized without her best friend. wanting someone back from oblivion. she thinks buffy is in hell because she is in hell, and willow's spirit is buffy's spirit, so how can they not be in the same place? willow starting the season trying to make everything better by reversing a suicide, but it doesn't make everything better, from willow's black-and-white perspective, it doesn't necessarily make anything better, the world isn't worth saving. and she ends up right back here. with the snake she didn't accept she had. trying to destroy the world and herself.
it's the fact that in the end, the young vulnerable girl willow is trying to give up to attain power is herself. she's sacrificing herself to the snake. proserpexa both has the power of the snake, and is totally bound by it. and so is willow.
it's the fact that what saves her is vulernability. there's sort of a transitive property you could read into "primeval"'s model of the scoobies-as-buffy. willow is buffy's spirit. xander is buffy's heart. so, transitively, isn't xander also willow's heart?
and willow's heart comes to save her. totally vulnerable. knowing he could very well die. says he loves her. no matter how afraid and vulnerable, and alone willow is, her heart, her spirit's heart, still loves her. and now im crying bye!!! except not bye because this is literally jsut me watching the fucking previously-on of "bargaining part ii" and i have the rest of the episode to watch and did i MENTION season 6 is gonna destroy me
