This ties into the theory that Ash is Voq. Especially in light of Ash having PTSD and flashbacks to what L'Rel did to him, whether it was rape, something more, or both, but mainly the "something more". How Voq would've been surgically altered to become Ash and how something besides just rape would give him such PTSD. L'Rel said Voq would have to give up everything and hasn't been seen since. It would be interesting if he were a Frankenstein type of creation with human parts but also ghastly. Victor Frankenstein would be L'Rel and The Matriarchs Voq was sent to. He'd have someone else's skin from top-to-bottom. Ridges sanded down. Before the new skin is applied. Redundant organs (Klingons have a lot of them) would have to be removed. Even typing all of this is gruesome. Could Ash be made up of humans who were mutilated as they were being killed? i.e. Skinned alive and poached for organs more specific to human anatomy. Also bear in mind the title of the episode where we last see Voq. "The Butcher's Knife Cares Not for the Lambs Cry". Is this what it could be referring to?
