Anon's been thinking about the Keystone ever since Q brought it up. A keystone is something/someone which holds the whole mass together. Something which, if removed, would cause the entire structure to implode, to self destruct.
Came to the conclusion (why it took so long?) that it has nothing to do with us anons. If it's one thing we anons don't have, would never accept (on earth that is) is a keystone. Fuck that. We have no keystone. That's what makes us anons. (That's also why many hate us, call us names, because we follow no man, but I digress.)
What then? The Keystone can only pertain to the enemy. It's them, and only them. who has, who needs, a keystone. Take their keystone away and they crumble, they are dead. It's now only half as hard.
