I liked this story, but I found it hard to follow.

Nice!

Your story was really very good. I think you should elaborate on it, though. Just add more senes, elaborate on every thought.
There wasn't enough character development either. One reason for this was that it was too short for how many events took place. You need to add more senes of data and Rebecca's relationship, and what kind of person rebecca was.
Also, Lore and his motives could have been a little more defined. I always have thought of him as more than just "the bad guy", and his motives didnt really seem that complicated...
but it was good, you should just add more

an excellent story! data's mental workings were so eloquently described; held my attention from beginning to end _.

one thing that triggered confusion was when data started using contractions at the end. *shrug*
