It is odd that SH had her memories wiped. Like, how would that help her with her mission? Maybe wiping memories would be helpful for deep cover, but once she got the artefact the memory block should have been removed to help her successfully escape with it...?

And her deep-down opinions (e.g., feeling happy that the tieflings were saved) do indicate some base desire to do good, which is at odds with a Sharran philosophy.
