Wow, her complicated past with Shiro, huh...
I am going to leave them up this time since I was a bit slow to catch them, but episode discussions should be created by the bot, rikka@ani.social. I went ahead and catalogued the threads (this one and Behemoth) this time so that they are recorded in the episode discussion guide wiki page. Also, rikka will create future discussion threads for these shows now as long as there are comments on the previous episode thread.
In the future, if the bot hasn't created a discussion thread for an episode that you want to comment about, you can request that the bot create one via private message.
Thanks for going through the effort of fostering discussions! I don't have the rule about bot-created discussions to try to stifle these kinds of things, instead, it is because in the past there has been a sizable portion of users that have no interest in currently airing series. So, having all the episode discussion threads created by a single, bot-user allows those users to simply block the bot and not see the content they aren't interested in. I wrote more about it here.
