"And with that, he was gone, leaving me alone. Only I wasn't alone." suggests a moment of separation, yet the narrator feels a strong sense of connection or presence that remains. This indicates a transition from physical absence to a spiritual or emotional presence that comforts or guides them.

"In fact, I knew I would never be alone again." reflects a profound shift in the narrator's understanding of companionship, implying that after this encounter or realization, they believe they are always accompanied by something greater—possibly spiritual guidance or an inner strength that will never leave them.
