Regarding that Arhu line, I don't think it's bleed-through, the same thing happened to me during my first playthrough with this build. I think we're simply not supposed to have access to the 'About Jake's corpse' line yet, or there's something wrong with the coding.
It's certainly a bug of some kind. He has a version of the line where instead he says "Oh, it's already been buried. Go talk to the Mortician about that."
