[ Shepard's decision to remain hidden didn't bother Saren. He just wanted the confirmation that she was the source Nihlus had, and now he had it, among other info. He assumed Shepard and Nihlus must have been here for around the same duration of time. Nihlus trusted Shepard, clearly, and Shepard trusted Nihlus enough to let him make this call. Not only that, but Shepard's trust in Nihlus was evident in the way she stayed out of the way.

Maybe what he said wouldn't sound so unbelievable. ]

Possibly the most sensible thing I've heard you say so far.

[ Saren scoffed, but he didn't sound like he objected, strangely enough. ]

If you're expecting resistance to such an ultimatum, you'll find none. I would have done my own assessments eventually.

[ Yes, Saren's casually suggesting he would have started to run experiments on his own body. So it's probably better that he had supervision. ]

But I imagine you won't be satisfied until I give you answers.

[ Saren paused. There's really no point dragging it out since he could guess time passed differently for Shepard, as well. ]

The last thing I remember is thanking Shepard. For...showing me the errors of my ways, and that I still had a will of my own.
