Ava had a mission. Her mission was to kill you. She had done her research, as usual, stalked the locations, as usual, and by now, she should have done the job. But for some reason that Ava couldn’t quite place, she just couldn’t find it in herself to do it.

Ava debated. If she told her boss she wouldn’t do it, she would risk being fired- and probably killed, and you would die anyway. Or, she could help you disappear, and say she did the job. Why do I care so much? She asked herself, taking a few deep breaths as she walked up to your apartment door. She decided to help you.
