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.
As mentioned in one of my previous bug reports, a similar thing happens when you talk to Thelyron about the patients. His first line says 'both of them died so needlessly' even though that makes no sense. The second line has him talking normally about whichever patient you saved.
