A/N – Plz review.

An hour later, Crystal, Grace, Sam and Daniel were the only ones left in the room.

The twins were packing up their books, while Sam and Daniel were talking at the front.

"Sam, are you ok?" Daniel asked sincerely.

"Uh, yeah. It's just…I sense Naquadah coming from someone in this room."

"Well yeah! That would be you wouldn't it?"

"No! I can't sense my own and since Teal'c isn't here it has to be someone else, besides me!"

Daniel's eyebrows furrowed in thought as he scanned the room for anyone that could be a Goa'uld or even a Tokra. "It's only you, me and the twins still in here…No! No Sam. You really think that they're…"

"I don't want to, Daniel, but it's the only explanation I'm sorry!" Sam started walking up to where Crystal and Grace were laughing quietly.

Grace looked up when Sam approached and smiled."Colonel Carter! How are you?" she asked.

"I'm good! Um, what are you doin?"

Crystal shut the sketch book and shoved it in her bag. "Oh, nothing! We were just… drawing"

Sam just stared, her ice blue eyes glazed over, remembering her encounters with the Goa'uld, most of them aren't pleasant.

"Why are you staring at us?...Hello?"

Sam snapped out of her trance.

"Oh, ah, sorry, what are you drawing?"

"Everything, anything, just random stuff, you know, when your bored you just scribble things down" Grace said politely, still smiling up at the Colonel.

"Well for me it's more writing than anything else but Grace here likes to draw a lot." Crystal said her fingers tapping on the chair in front of her.

"Yea I know someone like that." Sam said with a small smile. Grace and Crystal shared a look, a very confused look with each other. The statement the colonel said meant an obviously great deal, one the girls just didn't understand and one they hoped wouldn't need to be explained, it seemed like a long one. After a moment of thinking about a certain General, Sam realized that standing closer to these two girls made the urge to throw up overwhelming. "Ah, I'll be back" Sam walked back down the stairs to Daniel quickly, the sickness in her stomach subsiding as she got further away but not completely going. She had only one conclusion that she could think of and that was the combined amount of high levels of Naquadah flowing in the twin's blood. She walked the short distance from the stairs over to Daniel at his desk, her hand clutching her stomach as she fought down the nausea, her face clearly paled by it, something Daniel noticed. "I can definitely sense Naquadah, in their blood!" she sighed.

"Damn it! DAMN IT!" Daniel slammed his hands onto the desk, causing the two to look over at him.

"Professor, are you alright." Grace asked as she headed the down the stairs, her pace quickening seeing the look on Daniels face. "Sir?"

"Yeah I'm fine, just peachy" Daniel gritted through his teeth, while Sam smiled inwardly but worry quickly filled her happiness. She looked up at the girls and watched as grace moved down the stairs; caution was clearly on her mind. Sam could see they were worried; it was etched all over their faces, Graces more than Crystals.

"He's fine girls, nothing to worry about; you go and pack your stuff up." Sam smiled up at Grace; she returned the smile. Sam then smiled up at Crystal who just stared back down at Grace as she tapped her fingers on the chair in front of her still.

"You sure, I mean he looks pretty…sir are you sure your alright." Grace slowly moved closer and then looked over at the colonel; she was slightly hunched over as she balanced herself on the table beside her.

Sam could feel the sickness getting worse as Grace got closer, she clutched her stomach again, the urge to throw up becoming greater. She looked up and saw Daniel standing beside her with the rubbish basket. She smiled and waved the basket, as the nausea went down, she noticed that Grace had walked back up the stairs to her sister and started to pack her shoulder bag. Grace looked down at the Colonel and smiled, she knew something was wrong.

"Crystal?"

"Grace…"

"I think something's up, they're acting weird"

"Really, never would have guessed"

"Maybe we can do something to help or…"

"Grace. It's not our problem."

"But, crystal" Grace whined.

"No! we are not getting involved."

"Why?"

"Grace I don't trust them."

"Why?"

"Remember how many people we've trusted, and look how many people that let us down."

"But…" Grace looked down at the Colonel and Professor again and then back at Crystal. "…I think we're making her sick, every time we go near her, she seems to go really pale and looks like she's going to throw up."

"Oh yeah, we're making her sick, how? You ever think maybe she ate some bad shrimp or something."

"No… it just seemed logi-"

Before Grace could finish her sentence, the door on their right banged open, allowing two men to enter. One was of average height; he had short military cut brown hair, a black jacket with a white T-Shirt underneath and blue denim jeans. He was followed by a large dark skinned man; he had a black top hat on, a white jacket with a black shirt underneath and white pleated pants.

"Well, at least one of them has fashion sense." Crystal said, eyeing them.

Grace nodded. "Yeah. That suit is so cool."

Crystal looked at her sister.

"I was talking about the jeans. I prefer the laid back style, not the 'Oh I'm a private investigator' style."

"Hey, you two comin? or what? Cause you know how Teal'c get's when he's deprived of some much needed doughnuts." The first man said, not noticing that the man behind him had already started eating one.

"Colonel Mitchell. Was it not you who was becoming impatient with the wait? I believe I was very patient otherwise." The man who the girls now identified as Teal'c, had a very proper voice.

Grace and Crystal started laughing, but stopped abruptly when the larger man looked over at them. They picked up their bags, put them on their shoulders, gathered their books in their arms and headed for the exit.

"Goodbye professor, goodbye colonel. It was nice meeting you, Colonel Carter." Grace said politely, as she waved, and headed up the steps with her sister.

"See ya, Sir. Bye rando's and Colonel Carter." Crystal said half-heartedly, following Grace.

Sam started after them, reaching only meters away, when the nausea returned slowly, and she stopped, backing away.

"Wait a minute. Don't go."

"Why?" the twins stopped, and turned to face her.

Suddenly there was a loud bang and voices drifted through the door.

"Oi, watch it!" a man's voice said, and both Grace and Crystal saw Sam's face light up.

"Oh, that's who it is" Grace whispered to Crystal.

"Sorry Jack, but you really should walk faster." A woman replied.

"Yeah, yeah." From the door emerged a tall graying man who looked younger than he sounded, and a woman with long black hair.

"Oh my God. The first one was weird, but this one is just plain creepy. I mean we don't even know who these people are…" Grace spoke just over a whisper and immediately dropped her books on the stairs, causing them all to slide down to the four people at the bottom. Grace came back to her senses after Crystal gave her a sharp jab in the ribs, and she ran down to collect her books. Her and her twin were looking for the book with the dreams in it but when they found it, it wasn't on the floor, or in the one of the three sets of hands that held books. The book of dreams Crystal and Grace drew and wrote in, was in the hands of their professor, opened to a page with a picture of the tall graying man on it.

"Sir? Um, that's one of ours." Crystal pointed out.

"Uh, yeah thanks. Don't know what we would have done without it." Grace walked over to Daniel; with her bag now full with her dropped books. She held her hand out expecting to receive the book, instead, the professor turned around and walked towards his desk, flipping through the pages of the book.

"Uh, Danny-boy, what's up? I think these ladies would like their book back." The tall graying man was now standing next to Sam as he said this, and turned to smile at her. Sam started to step back and the man gave her a worried look. She smiled to reassure him, but continued to step back further, away from the girls. Grace turned around and saw this, so she moved closer. Sam held up a hand to stop her, but Grace continued to move closer.

"Daniel darling, what's wrong?" The lady with the long black hair stepped up the stage towards the professor's desk, with Colonel Mitchell behind her and started leaning against it. "Daniel"

"Ah, is this the book you two were drawing in before?" Daniel said and continued looking at the book; he began flipping through when he abruptly stopped. On the page was a circular machine with constellation characters on it. He looked up to find Sam paled and clutching her stomach, Grace stood in front of her. And then Daniel realized the closer Grace was to her, the sicker Sam got.

"Colonel? Are you alright?" Grace asked edging closer, until she was only an arm length away. Sam started to lose her balance, and grabbed onto Grace's hand which she had extended. It was like electricity flowing through them as their hands touched, and with a scream, Grace collapsed onto the floor. Sam stumbled backwards, clutching her stomach and called out the name 'Jack'. The graying man raced to her side at the call of his name, and circled his arm around her waist, guiding her to a chair, where he set her down, and noticed her hugging her stomach in pain.

Crystal ran to her twin's side, and rolled her onto her back. That's when she noticed her sister's locket glowing again, and tucked it under her shirt to hide it from prying eyes. Daniel dropped the book onto his desk and raced to his students', along with the woman and Mitchell on his tail. Neither one of them seemed to notice Jack and Teal'c attending to Sam.

"Daniel, what can I do?" The woman asked, laying a hand on his shoulder.

"Vala, just…stand back for a sec. Give her some space."

Vala did as she was told, while Mitchell made his way back to the desk, where the book was lying open on the machine. At one look, he pulled out his cell, and hit speed dial.

"General…I mean Jack. I'm calling SGC." He looked up from his phone when Jack didn't answer him, and saw why. Sam was crying into Jack's shoulder, and he had his arms around her, pulling her closer as she still cradled her stomach. Teal'c caught Mitchell's eye, and after looking between the twins and Sam and Jack, nodded to him. Mitchell nodded, put the phone to his ear, grabbed the book and started up the stairs, away from the others.

Sam pulled away from Jack, her pale face streaked with tears. "Jack. I need to move away."

"What?"

"I need to move up, away from the girls." She hissed through her teeth. Jack nodded, still confused, but complied, and he supported her until they were almost at the top of the lecture room, where he sat her down.

Crystal looked around frantically. "Where's my bag? Has anyone seen my bag?"

Vala searched the floor, and then saw a bag near the stairs the girls had come down. She picked it up and carried it over to Crystal, who grabbed it with a quick and quiet 'thanks'. She rummaged through the front pocket, until she found the box of sleeping pills.

"What are you doing?" Daniel panicked, not seeing what they were.

"It's all good, sir. Nothin' to worry about, this'll help her sleep."

"Why do you want her to sleep?"

"At the moment, your timing is horrible…sir. Just let me do this." Crystal popped two of the pills into her hand, and held them to her sister's mouth. "Here, Gracie. Take these, for me please." Grace opened her eyes slightly, and complied, swallowing the pills dry. She waited as the pills took effect, until she screamed again, and to her horror, the pills didn't work, like they did the first time it happened to Crystal.

"What's going on?" Vala asked, beating Daniel to it.

"Look, have you ever had a nightmare that you could feel, and you scream because it feels so real?" She didn't wait for her answer, "Well, that's what is happening, except while she's awake, and it's causing her great pain. At least if she's asleep, it won't hurt so much. But she's not so, it does."

"Oh."

Daniel felt Grace's pulse and was surprised to find it beating faster than it was supposed to.

"Are you guy's gonna help, or what? Maybe call an ambulance, or something?"

"No, we can't call an ambulance."

Crystal scoffed in disbelief. "Why not?"

"Because of what I saw in that book, and because I don't think any normal doctor can diagnose what's wrong with her."

"Oh and you know an abnormal doctor?"

"Like you wouldn't believe." Vala laughed, and then stopped when Daniel shot her a glare.

"That's my wife you're talking 'bout, remember?"

"Is this really the time to be bickering?"

Cam emerged from the door, and shoved his phone in his pocket. "An SG team is on their way, along with the medical team."

"No! it'll take too long and I don't think people will just walk by and ignore this." Daniel looked up at the colonel standing at the top of the stairs, and then noticed Jack, Sam and Teal'c sitting in chairs a few rows from him. He saw Sam being held by Jack as she cried, while Teal'c stood guard in close proximity.

Jack looked over at Mitchell as he rubbed Sam's back. "Mitchell call them back and tell 'em we're bringing 'em in, now"

"Yes Sir."

"Sam can you stand?" Jack looked down at her as she nodded. "Teal'c can you take the girl to Daniels car after I leave with Carter, she seems to want to stay away from them."

"Indeed O'Neill."
