Grey is really personal when it comes to mistages in language. It's not like I don't know that it's wish but I remember that my english teacher said once that some of us sing whisk and not wish when I was in primary school. The portrait in the background is called "God's will" he took this woman from the Earth and the man stood alone back on Earth. I don't know but altough Grey is mean he is kinda cute in this houseman outfit.
