Renegade : What are you so afraid of? That you might actually start caring for somebody?
Paragon : I care about you Miranda, and I think you care about me.p.
Got to stop lurking and pick up on this because I feel that this is a reflection of how some of Jack's dialogues are often interpted. Obviously your milage may vary, I personally feel that the Renegade dialgue options are Shepard deciding not to try diplomacy but instead trying a spot of poking. Taking an ice-axe to the ice-queen persona; hacking away at it and Miranda's convictions/hangups over her Mary-Sueness until he
finally gets a reaction which is 'hers'. Hence her suprise; she's so used to keeping herself under control the passion she displays catches herself off gaurd.
...well. That's how I viewed it anyway.
If you're curious about the supposed similarity to Jack's dialogues, I was thnking the ones where Maleshep is accused of being smug/know-it-all like this one:
Jack: Leave me alone Shepard, I don't want this.
Shepard: You're lying.
In much the same way as renegade dialogues with Miranda, Shepard's (paragon iirc) dialogue with jack is (imo) not Shepard being a smug ****** but calling her out on her behaviour. Because Shepard
knows that if either of them
really wanted Shepard to stop they would make him.
As you might have gathered, I sort-of see Jack and Miranda as opposite sides of the same coin (to an extent anyway). Since I tend not to keep track of the Miranda thread I don't know if this comparison is a sore point so apologies if it is.
