"I'm sorry… For all the things I said to you in the past. I didn't know the truth. I judged you harshly. Hurt you with words I never took responsibility for."
She looked at him, lips trembling, trying not to cry.
"And yet… You were still there every time I was in danger. So… thank you."
Kael turned to her. His expression was gentle, a stark contrast to the demonic power that was coursing through him. "It's alright," he said quietly. "I had complaints, but never disliked you for it, because I always knew that you were unhappy because you love your freedom, and your sisters. And I held you back. So I completely understand your predicament. Let bygones be bygones. However, there's something I want you to promise me."
She blinked, nodding. "Anything."
"I need you to keep everything you saw today a secret. From everyone. Your sisters… my sister… and even your mother. No one else knows this side of me."
