No, I agree; which is part of why the dossier stuff doesn't seem to fit anyway. You could play it with the angle that she wasn't always so hardened and focused on her duty to Cerberus perhaps? If the stuff with Oriana had sparked that desire in a younger Miranda, I could sort of see that working. Anyway, it's just throwing around ideas. It's up to jtav whether she thinks any of that fits or doesn't even matter.
As for my own purposes, how does everyone view the course of events for Sanctuary? From what I can gather, TIM was aware that the Reapers were either interested in the facility, or already attacking it, hence why he sent Kai Leng to get the data.
And if Miranda's line about "Things got really complicated when Reapers showed up. And Kai Leng", is meant as chronological as it sounds, then she could've been there sometime, finding her way around. At some point, Kai Leng must have beaten her to the tower and I guess she encountered him on his way back. I can't recall if she was in the tower when she was attacked though, and whether exactly the 'heavy resistance' was Reapers or Cerberus.
I guess it's something like:
1. Miranda arrives - either she has found a secret way through which she arrives into the facility, or discovers a secret entrance somewhere beyond the legitimate-looking front like Shepard does.
2. Searching around, she uncovers what has been going on. During this time, Reapers arrive.
3. Kai Leng arrives, making it to the tower (while the Reapers are focused on Miranda?) and retrieves the data. He abandons Henry and Oriana who have holed up in there.
4. Miranda encounters Kai Leng. He leaves without 'finishing the job' and also avoids Shepard on his way out.
5. Miranda makes it into the tower with Shepard not far behind.
The bits I am a little unclear on is whether she would've faced Cerberus troops beforehand, or if perhaps they arrived with Kai Leng. Also, I assume she knew Oriana must be there because her father was. Or maybe she gets some information our of Kai Leng?
Help plx.
