Dante knew that the penultimate moment had come. He informed his wife and daughter of his task, and the two of them gave him their blessings to go ahead in peace, as they were waiting for him.
Dante rolled his eyes because they were acting like he would be gone for long when an omni-clone was always present with them at the least. For all they even knew, Etz Chaim's solution might take a split second and he would be back.
Regardless, Dante kissed them both and left the Eternal universe, heading into the primal chaos that existed in between the universes. The moment he entered this void, the first thing he felt was the vast nothingness and the thunderous silence.
