He is the exact opposite of subtle. Everyone in King's Landing knows he is a schemer. He openly tells people not to trust him, how is that subtle? His interaction with Tyrion after the 3-choices thing wasn't subtle either. Bragging that he banged Catelyn isn't subtle.it's that he issubtleand calculated.
He isn't subtle at all but he is able to get away with it because he is so needed and people underestimate his ambition. Of course, Cersei could care less about needing someone, so the scene with him fits to me.
