After half-heartedly explaining himself by uttering bullshit that he gained an enlightenment hence he somehow happened to shed his skin and whatnot, Ken asked her explain the scene in front of her since he wasn't able to feel the changes in the room, except for the irony scent of blood assaulting his nostrils.
From Ela's perspective,
Most of the room was splattered with dark coloured blood which made her feel nauseated, and the side of the bed where he seemed to have been laying before he went to take a shower was patches of dry, dead skin laying here and there while literal footprints of the shed skin was on the ground where he had walked.
After assessing the condition of the room, adorning themselves in their clothes, both of them made their way out of the room, with Ela holding his hands with a blush as if she wasn't used to physical intimacy after making love until the whole room stank in their messy scent of sex which was now dominated by the scent of blood.
