Sigma never paid any thought to how the other 'Kurloz Makara' and the Initiate communicated - he had just assumed they'd had their own language, perhaps knowing themselves without speaking, rather than the use of sign language. But it was remarkably clever, and with Nill in the Arena, having such a skill was an asset.

It would also be an invaluable tool for communicating with Avoxes.

He stamps that thought out at once. "You are going to have to introduce me to her - or at least pass on a good word. I cannot imagine many Tributes will be happy to see me during my return visits to the Tower." He reaches inside of his coat - for now that he had some control over his own style of dress, Sigma hardly went anywhere without an overcoat - and retrieves a pen and notepad from his inside breast pocket. A student for life, he never went anywhere without them. He splits off a page for himself and passes the notepad to the Initiate.
