One of the things Cabot says when asked about rumors is, "They have heeded the call to power and are ready to raise arms at Chateau Crane du Gris." Chateau Crane du Gris sounds a lot like Castle Grayskull, don't you think? I haven't seen the new show, but grew up watching the original cartoon, and I remember He-Man raising his sword and saying "By the power of Grayskull, I have the power!"
I've never had Cabot say this to my Inquisitor until today, and I can't find this listed under the easter eggs.
