Is Leonard a Whispered? Spoilers for FMP The Second Raid

Is Leonard a Whispered like


   his twin sister Tessa? If so, do we know his specialty? If not, how did he become the leader of the opposition?
I think some of this is not revealed in TSR, so I've spoilered it.


   Yes, he is a Whispered. Not only that, he exceeds his sister's abilities both physically and mentally, and he used his knowledge to produce Arm Slaves for Amalgam. I don't think we know for sure how/why he became the leader of the opposition, though it's implied at some point that primarily he wanted more freedom.
