If this group needs one more royal, Dany can pose as one! She is a queen in her home world anyway, and in an #extra move, she probably brought her three-headed dragon crown with her, just in case it would come in handy on this mission. She also brought the set of golden bangles she has. She has a very pretty, eloquent way of speaking, and could also pose as a noble, if we're overloaded on royals.
