^I think if anything the build up came after Alina died, and Talulah's feelings of hate grew from that point onwards. I really don't like the idea of Talulah not having agency/reduced agency over her person during such an impactful scene.
It's fine if we don't agree though, nothing wrong with agreeing to disagree haha
^this. Ucchi just has no real filter in that regard so she's the most blatantly obvious about it. If memory serves it took her friends all of like five minutes watching her behaviour around Tomoko to connect the dots (and promptly start shipping/wingmanning them).
p sure Alina's death was just the "beginning of the end", both due to its own obvious emotional impact and because it deprived Tal of a vital emotional/psychological support and moral anchor point. The actual breakpoint that allowed the Snake to take over only came later, when she finally lost it in that one village - that was the last straw that broke her idealism and faith in "regular people". Kaschchey back in the day pretty much outright told her as much, and both Alina and... IIRC Patriot? had repeatedly expressed concern about her excessive optimism in that regard and how she kind of didn't have an ideological fallback should she be disillusioned one day. If memory serves in "present time" at one point Faust also made a passing mention about how she changed "after that village"...
^I think that's along the lines of what I remember. Talking some more about spoilers, Personally I really don't like the Biblical Snake, I would have been more invested in Talulah losing to her anger and losing herself without it. So I really hope we get to see more of Talulah in the future without the snake. I want to see more of her character under her own power, and I could see her with some writing improvements being an interesting villain along the same lines of someone like Magneto.
Mostly just the original, Ishtar, Space Ishtar, and Ereshkigal. There's also a couple AU versions and summer Ishtar, but it's arguable if they count. And there's TO-SAKA, but people mostly ignore her (being restricted to Capsule Servant helps in that regard)
