I didn't like Miranda at first because she wanted to put a control chip in my Shepard's brain. o_o; When she said the Illusive Man wouldn't let her do it, Shepard's response was exactly what I was thinking - "I'm glad he's in charge." Then I started to like her more after the loyalty mission, but she got into a fight with Jack directly after (because I did the missions out of order, so Jack's was completed a while ago) and I lost her loyalty when I didn't side with her. xD She was loyal for all of two minutes.
Right, back on topic. My Shepard's response to that Garrus image since she won't see it in-game because I never download anything...
Shepard: *stares* ...Wait, what? Sorry, I lost my concentration. >///>;
Illusive Man: *facepalm* Shepard, pay attention! ...To the mission, not Garrus!
Shepard: If I had ten credits for every time someone told me that, I'd be able to buy everything on the Citadel.
