It just hit me that Q has repeatedly posted the following line in recent posts.

>The silent war continues

More recently each word has been capitalized like so:

>The Silent War Continues

This sure looks like a signature like Q has used in many posts in the past and all of those signature refer to various movies (Red October, Sum of All Fears, Godfather III, Snow White, etc.).

I started hunting down movies by the name "The Silent War" and several pop up. I think this one is most notable as it deals with Chinese spies. This might be worth a dig.
