ive been yelling about this pesterlog in sids dms for 3 mins now hello
just.... so many things......
vriska wanted to fight jack to protect her friends. shes the only one in her group that god tied. its on her. ((so many trolls do this. feel like they have this task thats /theirs/. no one else can do it. no one can understand or shoulder the burden for them. the exact wording is "if not me, then who?" and isnt that just the perfect example of alternian society, expecting them to perform the impossible on their own, making them feeling like no one can help so they shouldnt even think of asking. thats why karkat as a leader and as a knight of blood does the impossible by keeping them together. everyone has always told them they CANT rely on others: the others are too weak, the others wont understand, the others are too good for you, you are too good for the others, etc. teamwork was something alien to them and yet karkat got them through the full game)).
if vriska goes fight jack, he follows her trail ((much like a dog would may i add)) and kills karkat and terezi. kills like half of her remaining friends, who are one of the biggest reasons shes fighting. she thinks of their safety before she thinks of her glory!! of course she wants to be savior of the universe, but she wants to be savior of her friends before that.
but most of all, killing jack means meeting the other session safely. means not having to hide anymore. means meeting /june/, and the other humans. means seeing their ways and behaviors so different from the trolls', yet something that calls to vriska. sure, karkat would fit better as a human, but her? could she fit as a human? could she be like a human, or a troll thats like a human, or even more of a human with a hint of troll? shes willing to give it a shot. and who best to try it with than her favorite human, the one who knows about her doubts about "the test", the one that doesnt understand the way she sees killing but tried to support and listen to her anyways, the one who doesnt judge her for being too much of a troll or not enough of a troll or for the things she did while trying to fit into her supposed place??
and none of that matters because if she challenged jack, she would lose. shed get her friends killed before he even bothered with her. and we dont even /know/ if she would win, or if shed survive even if she did.
none of that matters either, because on the alpha timeline shes dead. she laid her heart bare for june and now shell see and respond and it wont matter because vriska needs to die.
