What exactly has she done that has been "brilliant"? The gist of the show always seems to be 'take a look at this crazy woman who keeps mucking up the works!" She's only "brilliant" because they're telling you that she is.
Successfully turning the later head of Iran's intelligence agency? Realising Brody was dodgy in the first place when everyone else loved him? Getting him to confess and then get them to Abu Nazir? Realising that Brody wasn't guilty of the Langley bombing when the world thought he was? Making the Iranians look like idiots for taking him in?
That's five.
