Dar's list of names was of other people he was recommending for key government positions, including Secretary of State, because if the PE was going to have to change her foreign policy in view of Javadi's 'revelation', her previous nominee wouldn't be hawkish enough.
That was why she was supposed to fake Dar along during that meeting, in order to get the list out of him, and see who else might be on Dar's 'side'. Honestly, presumably you don't get to be PE without pretending all kinds of stuff all the time, but if her 'acting friendly to Dar' schtik was any hammier, she'd have had to throw herself into his slimy arms, saying 'I've always found beards strangely attractive....'
How hard would it have been not to do anything new? To NOT bob up and down serving him coffee and hovering like a butler, and then give him the hairy eyeball???
