The two of them worked together on picking a villain to attack. When they were done, they left the apartment together.
They walked over to the elevator and waited for it to open. The elevator came after a few seconds of waiting.
The door of the elevator had just opened when a wave of euphoria struck their minds. The boy swooned, but the old man was fine. He was fine enough to respond to the sudden attack aimed at the boy.
Kelvin had been waiting at the elevator for them to come. He hadn't attacked last night because Wrath had checked in on them and saw the old man sitting in front of the door waiting for him.
Wrath did so and told him because he had asked her for help. He was proud, but he was also smart enough to realize that he had too much at stake here.
Not only would he be fighting his first Omega, he would be fighting two of them at the same time. He had a lot to lose, so he had to make everything perfect.
