The portrait is absolutely horrifying. It looks like Dorian but a warped version of Dorian, withered with age. Traces of all the injuries he's ever received show on the portrait: burns are spotted around the face, two puncture wounds on the neck bleed, it's every sin, every injury, every trace of age writ large on his portrait.

Finally finding the dropcloth (how did it get under the couch?) Dorian tossed it over the portrait and gave Teekl a Look. A sort of 'don't try anything, cat' look. The last thing he needed was Klarion's cat to try and use the portrait as a scratching post.

"It's my portrait," Dorian explains, as he looks over at Klarion. "I brought it back to my apartment when the blackout happened. I don't..." He doesn't want Klarion just to see how much of a truly awful person he is. "You don't need to see it."
