Scarlet felt a sense of relief that almost made her feel guilty again, as she didn't feel like she deserved to not be hurt by the guilt she felt over the death of the people she killed.
However, she couldn't deny the relief she felt as she realized that in her last moment, she had decided to help everyone around her and maybe die forever in the process, instead of saving herself while everyone died.
She had used the forbidden technique, the Requiem of the Phoenix Song, which meant that she had absolutely done the most she could.
"You were in pain and desperate," Alex started speaking. "Most likely out of your mind. You instinctively wanted to go back home to protect yourself but you were stopped."
"Then, you were struck by the lightning and ran away. In the process, you gained a moment of clarity. You saw what was happening around you and felt the pain and guilt of having killed everyone. It consumed you."
