How so?
Her most prominent characteristic is being the champion of her personal brand of justice, which she does ruthlessly and with seething anger. I would've guessed 1w2.
She wants power through being loved. She works her way up by seducing. She works her way to gain Drogo's devotion through sex and power.. she loves for everybody to love her and follow her 'by choice' and out of adoration.. she seduces practically in her sleep.. and what she offers people is freedom, which is the 2's holy idea.
I made a stronger case for this on another website during the first season - I can copy it over here if this isn't enough. But I just find it sooo obvious! 2, anyway. I see [MENTION=5684]Elfboy[/MENTION]'s point about 2w1 actually.
Social 2s want to be loved by "everyone' and have social influence, but she still works her way up initially by having power over specific prominent people through being loved and adored. Later on, in a wider context, she works her way up by having power over many people through being loved and adored.
She is a clear heart-type, operating straight from the heart. Her disintegration to 8 is obvious in how fierce and brutal she is, and how much pleasure she takes out of her brutal revenges. Think about the woman she burned alive in the first season. There are many examples of revenge with her, and she is bloodthirsty and gets a thrill of it. line to 8 is clear. Line to 4 is clear in how she takes on this cause as her identity, and in how she expresses who she is ultimately, and her ideals, once she has gained power.
That "seething anger" you mention is fueled by pride. Her pride is tangible - you can taste it.
Any type can care about justice. It's not specific to 1. 1s are perfectionists. A personal brand of justice vs. a social brand of justice probably has more to do with confidence and believing in yourself, and perhaps MBTI (she is probably a Fi dom) than what enneagram type you are.
The question with enneagram is "why?" and "how?" Enneagram is defense strategies and coping mechanisms. Justice is a personal cause, but the question is how does she go about obtaining justice? She makes power-climbs by making other people love her. What she really craves deep down, is to be loved, to be powerful. She clearly wears a "mask" of power when she approaches enemies, but shows her sadness and vulnerability to her close friend, knowing he's in love with her.
2s do this a lot. They can put on a powerful mask when necessary, and be fierce and scary, but then when they're alone with someone who they know loves them, they show their worries, sadness, feelings of weakness.
By contrast 1s crave & need to be PERFECT. They need to feel morally correct. Daenerys doesn't care about this. She doesn't even blink during vengeance. Sure you could say "It's just" - but a 1 might have a moral connundrum about some of these actions, and wonder whether it's truly just. She doesn't blink, it's all from the heart. She doesn't have INSECURITY about being morally ambiguous or having to be morally perfect.
Her insecurity about being unlovable is harder to see, but you can see it I think, in the way that she takes such joy in being loved. When she frees people and they worship her and follow her, she derives tremendous pleasure. In the breaking of chains scene, she derives heartfelt pleasure in all of the men offering to sacrifice for her. She doesn't mind leading various men around by the nose; doesn't care if it's moral or not. She is loved.
