I've been wondering how long it would take for someone to color that image!
As soon as I saw that panel I knew it make a great pic
The way Undertaker and Sebastian are in adversarial roles, opposite of each other ... complete with Sebastian's hand bear the seal near Ciel's marked eye while Undertaker's scythe blade coming between Sebastian and Ciel showing their roles.
All the while Grell stand behind Ceil with his back turned, showing how he doesn't have an interest in Ciel himself ... but following Grell's eyes we see she does have interest in Sebastian.
The scene was a masterpiece, glad to see someone color it.
