So I have valiantly dispatched cheesily one-shot the big bad with Mega Stab (hey, stop cowering between those lava tiles and you'll get a stand-up fight next time!) and watched the ending slides. Most of them were fine (and/or amusing), but there was a minor issue -- they didn't seem to realize that Louise was dead! I got the 'good' ending for the Louise/Madeleine pair ("Louise, unused to winning games of chance that she hadn't rigged herself...") with both of them on the screen unlike the "bittersweet" blurb I got for the Hashmals (Nalia and Gavrielle were both dead... though in retrospect, I haven't seen any mention of Nalia anywhere, I only noticed her name because she said something when she died in the basement fight).
Actually, I checked Ending.xml, and couldn't find a blurb for "Louise dead, Madeleine alive".
