Frederick nods ponderously, which mostly means he dips his whole from half. The way his skull is attached, he can't really nod properly.

Hmm, that's going to be hard to explain, when you don't share a language.

Frederick draws an arrow next to Kilroy pointing to his right, then next to it draws a deer skull. Or, well, it's not a very good drawing, but it looks kind of skull-ish and has antlers. He was a human. Now he's this. An effigy, his granddaughter had called him. A poppet. A twisted one.
