Sorry for typos in advance, im at work.
I hadn't tried other routes when the time I wrote this. So I just played the
'Killing Cass' route in the morning and it looks like Ludwig ain't happy we
killed Cass unlike M.W . Though in the path we choose not to
kill Cass he
dies and
reincarnate into a cat bod and tells us that 'the mistress' will show herself and answer our questions. Is M.W 'the mistress' he talks about, if it is why he thinks opposite on the matter of Cass?
Another thing I noticed in 'Killing Cass' route is that M.W says there is 'another blind snake (so there is only two snakes according to her or she simply doesn't talk about the third one...?) coils around us - the one behind all of ours misfortunes, pulling the strings, unaware that she herself is a puppet' unlike the Crone who said there were three snakes and they were only watching our moves (well Cass certainly acted so this kinda irrevelant as of now) and if we kill one of the snakes remaining ones will strangle us yet eliminating all of them will lead us to abyss. So if we get back to the 'mistress' Ludwig talks about it is probably the Crone, both talk about maintaining the balance in some way while M.W thinks the opposite clearly. Though, ofcourse M.W could have basically captured his soul and trap it in a cat bod and she is the mistress he talks about y'know. And anyway, who is the 'another blind snake' M.W talks about, Alaina? King fits the bill but M.W says 'she'. She is the one who advises the king about exiling the Prince afterall.
There are two versions of present shown by M.W depending on whether Cass is alive or not. In the route Cass is dead Alaina talks to Conrad and saying someone is threating Prince's life and calls him to a belltower. Lets say she speaks true: who may that be? Though there is a possibility she wants to lure him there and kill him, ain't she saved him once in previous update, why would she kill him now? She may want to manipulate him but on the expenses of whom? Alaina's plans may have changed based on Cass' state, Crone said if we kill one of the snakes others will act and M.W says another one is strangling us rn, so there is that.
Also don't forget, the second time Alaine showed us the past (the past where Prince poked the eye of the Cass) she defends Cass against the king and advise him to exile MC. Cass and Alaina, what or how is their relationship exactly? I would say she is the one who manipulated her from the very beginning but she was beside the MC whole time AFAIK.
