It would seem that Twilight should have killed you as well as her best friends, since you could have interfered with her plans, but she did not. You were her lover even before her madness and God complex, apparently this played to your advantage.

She had certain plans for you, she didn't want to kill you, she wanted you to serve her, be her puppet.

— I have been waiting for you, now you will worship me or I will punish you.

Twilight said, looking at you with a monotonous voice.
