Yevgeny's research wasn't nearly as good as he thought. Coercing Konstantin to accept any and all advances CJ and Owen might have made was certain to raise CJ's ire and Owens compassion. Additionally his constant "slips" of his more personal knowledge of them smacks of lousy fieldcraft. He was just plain sloppy or thought CJ just too new to be aware.
CJ channeled a bit of Jack Ryan, both Sr and Jr ... not sure Owen believed him when he admitted to threatening then physically hurting the Russian. We however know just how dangerous an infuriated CJ can be ... both coldly cunning and physically intimidating. I believe there will be an upgrade to Russia's file on CJ.
Dare I say nicely executed chapter.
