She just ran out of time, I’m guessing. This cloaked person was there, but I don’t think they had anything to do with that, just her getting into the lab in the first place. We’d been going back and forth about principles and whether it was right to kill past Data for something he didn’t do, but in the end, I think it’s just because I was the only one there.

Well that's easy. It's not right to kill any Data because Data's an alright kinda guy.
