Tony sat at his desk, as he searched for a pen he came across an old picture of a young girl with brown shoulder length hair, Piercing blue eyes. She appeared to be about sixteen.

"Tony"? Kate asked as she stood in front of him, shifting a stack of files in her arms. She tilted her head, she hadn't seen him space out like this in awhile and though she hated to admit was starting to get worried. She couldn't believe he wasn't seeing Gibbs give him death glares from across the room for the past ten minutes. "Tony"? She asked again touching his shoulder carefully.

Tony jumped, as he looked at Kate Sheepishly. "Huh?"

Kate looked at her partner her face showing concern. "You ok? Your just starring at that picture like you lost your best friend. Not to mention you haven't even noticed that Gibbs has been giving you the death glare for about the past ten minutes now.

Tony gave a small smile. "Worried about me huh." he said grinning.

"As if, I just don't want to get stuck with all the paper work." Kate shot back.

Kate pointed at the picture. "Who's she, she's a bit young for you don't you think?" she asked.

Tony got this far away, sad type of look in his eyes. "She's my sister." he answered.

Kate's mouth fell open. "You...have a sister?" she asked in aw, wanting to know more.

Tony nodded. "She's probably changed alot, she'd be about twenty now." he said, his voice showing a fondness Kate had never heard before.

Kate smiled. "She sounds nice, you should bring her around, I bet she's got tons of embarrassing stories to tell about you." Kate teased.

Tony's face clouded up. "I've got work to do Kate." he said, he quickly put the picture away and went back to work.

Kate knew that she'd pressed a button about Tony's sister she just wondered why he had gotten so upset. She figured she should ask Gibbs, he'd know Tony for quite awhile. She went back to work, though Tony was heavily on her mind.
