Anakin frowned lightly. "I'm sorry. That..." He sighed, then chuckled. "I'm reliving the past several months in a matter of minutes. Okay. I was having some... identity issues several months ago. I had fallen back to the Dark Side. Vader was in control. He fought with you, and in the course of the battle, removed your hand."
Lightly, he brushed his gloved fingers against hers. "It helped to bring me back. I was... appalled at what I had done. So I made this hand for you. I know it's no replacement, but it was the best I could offer." He pulled his gaze up, to look into her eyes. "You helped save me, Jaina."
