"Because someone should tell them." Greg let out a nervous laugh. "Especially with all that's been going on around here. I'd hate for him to actually start dating her and then find out later that we knew that she was his sister, especially since who he thought was her actually turned out to be Heather."


It took Catherine a moment to get her words out as she held her robe around her body. "Ecklie passed away a short time ago."

Warrick was a little confused as to why Catherine seemed visibly shaken at that news since it wasn't unexpected. "Cath?" He touched her arm gently.

Catherine met his gaze and had tears in her eyes. "There was a plane crash in Paris. It's Nick and Sara."

Warrick suddenly felt sick to his stomach.


The CSIs all made their way to the lab, even Grissom when he was discharged from the hospital headed in to the lab rather than follow the doctor's orders and go home. The break room TV seemed to be stuck on CNN where footage of the crash scene was played from as many angles as they could show it.

"Can we watch something else?" Greg was visibly upset.

A concerned Mia placed a hand on his shoulder in support. She hadn't known Nick and Sara very long, but she'd hit it off with Sara and she was feeling disbelief at the thought that just after they'd found such happiness that they'd be hit with tragedy.

"Greg's right." Warrick agreed as he unashamedly held onto a sniffling Catherine as they sat on the couch. Nick and Sara were like family and the thought that they'd lost them like this was nearly unbearable.

Brass turned the TV off. "We still don't have confirmation that they made it onto the plane. Sophia's checking on that right now." He was even more somber than normal.

At the mention of Sophia's name, Greg and Mia exchanged a glance. Greg cleared his throat and looked over at Grissom. "Uh, Grissom, can I talk to you?"

Grissom looked perplexed. "Right now?"

"Yeah, it's kind of important." Greg furrowed his brow.

Grissom let out a tired sigh and regarded Greg over the rim of his glasses. "Greg, whatever it is, just say it."

Greg glanced around the room a bit skeptically. "Uh, here?"

Grissom narrowed his gaze at Greg. "Yes." He motioned to the wheelchair he was confined to for the moment. "I'm not really in the mood to wheel myself anywhere."

"Uh, it's just that…" Greg looked unsure of himself.

"Greg!" Grissom practically growled. He had kept his composure through every other thing that had happened over the last few months, but Greg's indecision was the last straw.

"It's just that Sophia and you…" Greg looked up just as Sophia walked through the doorway to the break room with an odd expression on her face.

"Sophia and I what?" Grissom looked at Greg with a studied gaze.

"Yes, Greg, what?" Sophia regarded him with a bit of suspicion.

Greg swallowed hard and plunged ahead. "Well, Mia was working on comparing some samples and she found out that Sophia and Heather aren't related at all."

"Yes, we know that." Grissom sounded impatient.

Sophia looked amused.

Greg continued. "Well she was going to run Heather against any unknowns to see if she had any other identities and well, she ran Sophia's by mistake."

Mia interjected and looked at Sophia. "Your sample was still up when I ran the test and I was waiting for it to time out before I ran the correct one." She smiled hoping that this wouldn't reduce Grissom's confidence in her ability. She'd already had an uphill battle because she wasn't Greg.

"What we're trying to say is, we found something." Greg looked at Sophia and Grissom with a tentative expression.

Grissom was impatient. "What?" He was tired and irritable and not having any firm details about the plane crash was unnerving.

Mia blurted it out. "You're related." She gestured to Grissom and then to Sophia.

Two people could not have been more surprised and they spoke in unison. "What?"

Greg smiled smugly. "It seems that you two are first degree relatives. By the amount of markers in common, my guess would be that you're brother and sister."

"But…I, she, how?" Grissom looked dumbfounded.

Sophia was surprised, but not shocked. "I always knew I probably had siblings somewhere since I never met my father, but I never expected to find out quite like this."

"We have the same father?" Grissom looked at her in disbelief. "I mean I supposed it's possible…he left when I was five."

Sophia looked at him sympathetically. "He obviously didn't stick around long enough for me to remember him either, Gil."

"Wow, a sister." Grissom looked at Sophia trying to absorb the information.

Catherine cleared her throat. "Uh, as long as we're dropping bombshells here…"

Greg's eyes widened as he turned towards Catherine and Warrick. "You aren't having a baby are you?"

Catherine rolled her eyes. "No, we're not having a baby, at least not yet." She smiled a little as Warrick hugged her a little tighter.

"I asked Catherine to marry me." Warrick only wished he could have shared the news at a happier time.

All of this was a little much for Grissom. He looked completely worn out and with the lack of any specific information available about the plane crash he was starting to feel sick too.

Brass turned towards Sophia. "Did you find anything else out about the passenger list?"

"Oh." Sophia had almost forgotten the reason that she'd come into the break room in the first place. "Yes, the list you had was just the list of individuals who had tickets for the flight, not the list of those who had actually checked in."

"And?" Catherine sounded hopeful for the first time since she'd heard the news of the crash.

A smile began to spread across Sophia's face. "They never checked in for their flight."
