She accepted his words. After all that had happened she didn't find it right - she didn't have the right - to contradict Stitch. She listened to his words, berating herself for finding no meaning in his rage. What would make Stitch understand that her choice could not be driven by anything else but the sake of her love? Perhaps she had been selfish, perhaps her soul had a dark shadow. Silence was her acceptance of Stitch's accusation: she chose the book over the children. It was a sacrifice that she was willing to put up with. It was a burden she was willing to carry. But she didn't expect Stitch to agree with her, in fact it was her fault that Stitch couldn't understand. If she had laid out her whole story before him, the blind man would have still accepted her. Stitch would have welcomed her in spite of everything. Maybe Stitch didn't have to hurt so bad, if only she dropped her robes of selfishness.
She watched him step back, and she held her glowing hand to where her heart should be. The warmth enveloped her soul. She was a mix of emotions, and she wasn't built to sort out too many feelings at once. Silently, without tears, she walked towards Stitch, grateful that he had at least found it in himself to forgive her. Forgive, not forget.
"Where Yaska had been," she whispered, stepping closer to Stitch. Her voice held a melancholy that she pulled out from the depths of her soul. Maybe it wasn't apparent, but she was sad as well, even more than Stitch. "It had been dark. And it has been so dark for many many years. In this house," she stepped closer, "I..."
Was she going to break down again?
"In this house I saw a light. But maybe the shadows in my life had been too many, that I absorbed too much." She was very close to Stitch, this was the final moment that they will share, and it will be a long time before they meet again. The Nuit was a breath away from him now. "I didn't mean to."
So this is goodbye. An even more painful farewell for Jilitse, "Stitch," she moved her cheek against him, and she placed her glowing hand upon his face, "Thank you for reminding me what it's like to be human, and for giving me the chance to be your friend." Lightly, in a way that she had seen the kids do the same for Stitch, she gave him a kiss on the cheek, a kiss that was barely even there.
And with that, she took all of her belongings - even the beaten up golem - and left the house quietly, never looking back.
