Be His Soul Sister

She was his best friend. As she watched him dancing w/woman who held his heart, she realized she'd been holding onto him for too long, & it was time to let him go. & though he didn't return in love w/her, he returned her w/a part of her soul connected to his, part of his heart permanently attached to hers. She could live w/Ziva being his soul mate, if she got to be his soul sister.
