The long wait and restraint, all the unrelated things done to kill time, had all been meant to numb the enemy before launching this dishonorable sneak attack.
Deathstroke had previously acted like a street punk, running around right under the enemy's nose. Though he had beaten back Pralaya's subordinates several times, to that mother, those actions had probably looked like a cat in a cage puffing up its fur to keep people from touching it.
So, as time went on, she might have formed the impression that this Deathstroke was quite capable, but still operated within the cognitive level of an ordinary person—still inside the cage.
After all, even when spying, she could not see Deathstroke. She could only see a Batman, and everyone knew Batman represented ordinary humans.
That somewhat blurred her assessment of Deathstroke. Every time she saw Batman's appearance, it reinforced the impression that he was "an ordinary human who was a little less ordinary."
In particular, Deathstroke's plan to create the Cosmic Tuning Fork probably made the Goddess disdainful. He had employed multiple concepts, only to recreate a technological device?
The Cosmic Tuning Fork was Anti-Monitor technology. The Monitors' technological level was naturally extremely advanced by human standards, and it had basically all come from their mother, Perpetua. But if one really traced the lineage, Pralaya was even Perpetua's mother.
Those technological methods were probably like children's toys in her eyes. She should have seen Deathstroke create the Tuning Fork, have a gorilla operate it, and restart the Timeline countless times because of it.
Using so many advanced concepts to do something so boring was like watching a child with power and knowledge use an excavator to dig out an ant nest. She had tried to stop him, merely as a token gesture.
But from that
