The Apex Caleb Moment

Caleb and Ava are left as the only two conscious entities in this enormous place. There's something about it which feels like she just knows to stab him right through the ribs. Because a robot, of course, wouldn't have the kind of human reluctance or squeamishness,. But it would also be able to adjust its pressure every microsecond to make it a smooth stabbing... So it is exactly how an AI would stab you, like utter cold perfection. Yeah.
