femto sounds like a disease

I'm wondering if this "Abduct Casca" plan was a spur of the moment thing or if Griffith was planning this all along. I would like to think that it's the latter, since it's fucking Griffith, but even though we've grown to know him as this master strategist we also know that he is not immune to "moments of irrationality" a.k.a. stupid/mean emotional decision making (whether it's sleeping with the princess out of wedlock and getting caught or R-wording your friend's lover just to be vile and spiteful) and that he can't still spin things in his favor (i.e. no Griffith wasn't planning that R-word scene in some master scheme like how some would like to apologize away BUT he definitely took advantage of the aftermath b/c causality).

Of course if that's not the case, I just wonder at just what moment Griffith decided, "Ya I need to kidnap her." I guess we could potentially get a better perspective if we get into Griffith's perspective (which we don't really get a lot of post-reincarnation) and how he and the child became one body, but not necessarily one soul/mind.

Back during the post-Conviction Arc, at the confrontation on the Hill of Swords, it's evident that Griffith is aware that baby whose body he stole in order to reincarnate into the world is still aware itself. BUT, now that I think about it, was Griffith even aware that the body belonged to Guts and Casca's child? Was it something that he also had to piece together over time? Like, he's not going to say this in front of people (because it's a sign of weakness), but he most definitely was experiencing lapses in memory and black outs during the full moon. Maybe at the beginning he had no awareness or control over these transformations but somehow he figured stuff out.

I guess maybe it was in chapter 358, right after he and Charlotte shared some "tea time" together and she fell asleep. He was anticipating the transformation and that was the last time we saw him in Falconia before the arrival of Moonlight Boy on Elfhelm. If he was seeing into Moonlight Boys mind bit by bit over the duration of these last few arcs, he definitely might have been piecing together Guts and Casca's travel path, their activities, and more importantly, their relationship to the boy and the boy's own feelings toward them (which would surmount to the conclusion of the boy - whom he stole the original body of - being Guts and Casca's child). Of course I'm remembering the world tree has a lot to do with cosmology of the Berserk-verse, though I'm not sure how much either Griffith or Moonlight Boy know about its function as a sort of ethereal super-highway (if the Moonlight Boy was operating independently from Griffith up until at least very recently, how was he compelled to use the world tree to find Guts and Casca wherever they were in the world?).
