I have to say, Joan's conclusion wasn't as good as I had hoped. it was... fine. but I wanted to really dig in the screws. instead, John Garrideb -- who I like a lot! -- shows up to be her witness partner. it seems like both of them are a little more remorseful than I would have expected from the lady who was abusing her husband not two days prior. apparently it's just that kind of relationship?
we prod John, find a piece of a blade and eventually tie it to the weapon. it's pretty much over there. the last piece of evidence - the book in the victim's hand -- didn't even really make sense to me. I got it fairly quickly, because you don't have much evidence, but I didn't really get how that was the big piece of evidence that put the case away. instead of Joan going down with a bang, she... faints, and John catches her, and probably hurts himself more in the process? I don't know. like most things with this game, it's unfulfilling.
we reach the end of the case and take up residence in Sholmes's attic. this is to be our law office, I guess. the game loudly hints at some Bad Stuff coming in the near future, much like it did with Kazuma. case 4 feels more like a case 3, very middle of the road, and it's weird to think that this might be the conclusion.
The funny thing is that while in-universe it looks like John comes in for support, its actual purpose in the cross-examination to the player is to provide his pipe as evidence as without him you wouldn't be able to conclusively link the knife to them. Although by that point there's already much more evidence linking Joan than Soseki. Anyway, case 5 is way better than all the previous cases thankfully. ---
