i don't know if this is the right blog to ask or I should ask on the other one, but speaking of zeus! i wonder if youve ever written anything or had headcanons about how the rest of the elder six reacted once he was back from his ordeal with typhon
for questions like this, either one is fine!! and boy am i rubbing my hands together over this one, because it is juicy!!! i don't know that i've ever addressed this in any detail (with the exception of hera, i believe), so i'll dive right in!
i believe that the general response to what happened with typhoeus were variations of horror and outrage. remembering that all of the other gods fled when typhoeus came knocking really emphasizes their fear at facing such a powerful and dangerous foe. none stayed to fight, save one. all of the gods were fearful of typhoeus, and this is only more deeply cemented after seeing just what the creature was able to accomplish. even though zeus prevailed in the end, it was incredibly clear that this was not a battle won easily. the gods had reason to be afraid.
because if zeus could be defeated, tortured, and made low by a single beast, what chance would any of them have stood? together, they may have prevailed, but any one of them could have suffered the same fate. they learned of that fate after their all-powerful leader suffered it. so when zeus returns and they see what has become of him, there is horror. there is outrage. there is, undoubtedly, guilt.
( i like to headcanon that some wanted to stay, such as athena and hera, but seeing what danger was coming and that no one else was staying to fight, zeus sent them away too ).
as for zeus' siblings in particular, i think the responses vary a little, but are ultimately all rooted in the same emotions; fear of what could have happened to them, surprise at how something managed to fell zeus, anger at the beast for what he had done, and guilt for fleeing when their aid could have spared zeus.
hestia's response is the most humble and empathetic, i think. she cared little about the implications and what they meant for her - she was mortified to see zeus in his state. she had seen her family members through a lot of terrible things, but this was something else entirely. she was seeing a broken zeus, in both body and spirit, and her heart ached so deeply for him a part of her broke that day, too.
i think hades and demeter shared similar responses. again, horror at seeing zeus of all people so broken. guilt at their lack of participation, knowing that their help in particular could have truly turned the tide. discomfort at not knowing how to fix it, how to help zeus, how to undo the damage that had been done. ultimately, neither of them doing enough.
poseidon was complicated, too. i headcanon typhoeus to have happened after his attempted coup, and so there is a lot of complex feelings between him and zeus. ultimately, poseidon does not like seeing his brother this way. it leaves a sour taste in his mouth he realizes is guilt much later on, but in the moment, i think poseidon's biggest concerns are with the fact that clearly zeus is more powerful than he, and zeus fell, so what does that mean for him? that he never would have stood a chance? it's selfish but very real, i think.
zeus and hera were also not in the best place prior to all of this. zeus' return reunified them, but under the worst possible circumstances, and hera's guilt ran deep. she felt she should have stayed, fought harder, done more, but she didn't and she knows zeus will bear the weight of what he experienced forever.
as for zeus... there was a very real amount of time in his captivity where he believed no one was coming for him. that he has lost, and that this fate was it for him. while he does not blame his family for what happened, there is a part of him that felt what remained of his trust in them shatter, and he's spent a long time trying to recover it. however, the thing that the ordeal did for him, besides giving him endless amounts of trauma and physical scars, was it was the catalyst for some of zeus' biggest changes - the zeus we see afterwards is fundamentally changed and in many ways, better.
