I'm gonna talk about the Aldrich boss fight so spoiler warning.

So in the opening cutscene (and every other interpretation of him) he's depicted as this giant blob of black sludge that has this werid clam like crown on top. Ok cool. But why is it when you fight him, he's half normal looking, half werid black ribcaged snake thing. Im not trying to troll or anything, I've just always wondered why there's such a continuity error. I've watch a bunch of lore videos, watched other cut scenes that Aldrich is in but I haven't seen one remnant of his human half. Is there an explanation or are we chalking it up to From not being able to have a gigantic blob be a boss fight cause if the polygons and animations?
