Speaking of Yasu, for anyone who's interested the
"Stupid Goats Seacats Reread Session tumblr liveblog / analysis" is now done with Episode 2.
The google doc with every post for easier reading can be found
here.
For anyone who missed it the first time around, the link for episode 1 is
here. It's a reread of Umineko by two different people each giving their own insights, with a specific focus on Yasu's perspective. It, imo, does a great job of highlighting a lot of the stuff that was troubling her, and shows just how much of it Ryukushi baked into the story even early on.
