I gained Miranda "loyalty", after completing her storyline and she got to converse ansd speek with her sister, got follow up Email ...
I gained Jack (Subject Zero) loyalty after completing her storyline as well...
I interrupted their (Miranda & Jack) argument and took the Middle option (Paragon) and later continued to have conversations with Jack, however perhaps due to my Paragon level being between 40-65, I got cold shoulder from Miranda (and it appears lost her loyalty too) , telling me to go see Jack if I wanted to Talk...After many "roundabout" conversations with Jack endign with "com back I have to think about it" type attitude, I broke it off with her (Jack) by chosing the Middle Selection (nicer way)...After all is said and done, when I saw Miranda "Go see Jack if you want to Talk", Jack said "F@#$ &&F" every time I go to see either of them...no communication difference through to end of Mission...Jack lived and has it so happened "Miranda" dies... So I am hoping that though I dissed TIM and am going to do what I was brought back to do, I wonder if the same can happen to Miranda, because Jack may be "B" to deal with in ME3 if all she says is "FA#$ &&F"...
