Crossover Crossroads (The Kell and Maille Story)

"I missed you." Kell said simply, knowing it for the truth it was. This was way deeper than he'd ever been before. He swam to the side of the pool and stared up at her.
"I missed you too." Her lips parted, and he nudged her closer, memorizing each soft feature.
"No, babe, you got me square in the---" He chuckled as she drew back with a startled gasp recalling where she had just accidentally kicked him.
Maille got up and went to get a towel. Kell followed her slowly, feeling returning to parts he'd rather have forgotten about.
"I have plans for you. Dress! Dress! Dress!" he announced as she began to head for the kitchen. She whirled around.
"Plans?"
It was dark throughout the house. She was simply a silhouette against the city lights. And standing there, he knew. She was the one. She could never go back to her house. He had to keep her there, with him, always and forever.
And what did forever look like to this sheltered little Mann Girl? At what point would Kell be able to reveal his secrets to her? Could he lay the decision to stay with him at her feet? Could she accept the man he was now? Or would knowing the truth destroy the fragile unity they'd haltingly built? He hesitated.
What would be the cost?
