My thoughts have stalled halfway through, and I can't seem to formulate them properly. I'll just offer a weak, lazy IMHO:

- Freud's dismembered body was found near Xostor's hut; what a difficult journey he must have had that night! The poor fellow had his limbs amputated one by one, and then his head was taken!

There are no more mentions of me as the one being acted upon (protected, healed, supervised, etc.), so Freud came to kill me. There are two possibilities: either a leukocyte protected me, and Heroin arrived, or Heroin arrived, but he was dealt with earlier. I'm leaning more towards the second option.
Why Heroin specifically? Let's compare it to Arandor's death:

- And even though Arandor wasn't the most righteous citizen, we will mourn him.

- a hint at a not-so-good status.
And in Freud's case:

But don't worry, nothing and nowhere will be hidden from His gaze. The Church will take care of a proper burial.

- I think this is a hint at a positive status, and among the killers, only Heroin has that so far.
My lazy IMHO is over! Maybe I'll chat more tomorrow
