Well, it was clear already in the last ep Anew was a real mole, so that wasn't as such a surprise. Her moleness was actually made more realistic (though that's a word that shouldn't be used carelessly when talking about Gundam series) by the fact how attached she got to the CB. The real history is surely full of spies and infiltrators that went through agony because they really fell in love only to be ultimately forced to betray one side or the other. Seeing how these innovators are so miserably remote controlled by Ribbons, Anew's agony was probably twice as bad as she couldn't even make the choice by herself.

Speaking of Ribbons, I still don't understand why CB doesn't go and nuke his palace. Considering the strict hierarchy of innovators, killing Ribbons should be a blow even though no. 2 would eventually replace him. Moreover, Ribbons possibly cannot have any fancy position in the society, if the innovators so far try to maintain some sort of a facade of democracy. Meaning, for the world at large assassinating Ribbons would be nothing but one isolated incident of terrorism.
