Daniel had barely finished his speech when the klaxons went off again.

"Unscheduled off-world activation!" Harriman announced, closing the iris.

Carter moved to the dialling computer to see if any known IDC was being sent.

Hammond appeared with O'Neill and Teal'c close behind.

Kaitlyn moved back a little as the group crowded around the computer, barely noticing her. She watched as a large metal circle was closed inside the inner ring. It appeared to be some form of protection. Kaitlyn noticed the burly man walk in behind Jack, a face she hadn't met yet. He had an unusual branding on his forehead though she couldn't quite make it out without looking like she was staring.

"Receiving Tok'ra IDC, sir," Harriman advised.

"Open the iris," Hammond ordered.

The iris was opened, and within moments, Jacob Carter stepped through, the event horizon vanishing behind him.

Sam smiled, happy to see her father and headed down into the gate room, the rest of SG-1 on her heels.

Daniel gestured Kaitlyn to follow, assuring her it was OK.

Kaitlyn felt awkward again, wondering what the hell a Tok'ra was. She really felt like the fish out of water. Deal with it, she scolded herself. You are the fish out of water, and followed Daniel down to the gate room.

"Stand down," Hammond ordered the SFs, to which they obeyed and lowered their weapons.

"Hey, Sam," Jacob said warmly, embracing his daughter.

"Hey, Dad. Good to see you."

While Jacob and Sam caught up for a moment, Daniel moved between Kaitlyn and Teal'c. "Uh, Kait, this is Teal'c. He's the fourth member of SG-1. Teal'c, this is a former colleague of mine, Dr Kaitlyn Richards."

"Nice to meet you Teal'c," Kaitlyn said with a smile. Interesting name, she thought, wondering where it originated from. Something about him gave her the suspicion he may not have been from earth.

Teal'c bowed his head gently in return.

Hey, folks," Jacob said, acknowledging the rest of SG-1, though there was a face he didn't recognise. "New recruit?" he asked Jack, wondering why there was a civilian in the gate room.

Jack opened his mouth to answer, however, Daniel beat him to it. "Not exactly, Jacob. This is Dr Kaitlyn Richards. She's a former colleague from Chicago. Bit of a long story, really. Kait, this is Sam's father, Jacob."

Kaitlyn smiled, though she thought it odd that, if this was Sam's father, why had he come through the Stargate? The whole thing was damn confusing. "Hello."

"Hi there," Jacob said simply, a little puzzled as to why she was here, though he'd probably find out soon enough. He turned his attention back to the group. "I wish I could say I was here on a more pleasant note, folks."

"What's wrong, Dad?" Sam asked concerned.

Jacob looked grimly at the group. "The Tau'ri are in danger," he said simply.

O'Neill rolled his eyes. "Oh, is that all! So what's new, Jacob? Wouldn't be a normal working week here if some snake head wasn't making a threat against the SGC or Earth itself," he quipped.

"Well, you're right about it being a Goa'uld. Ever heard of Osiris?"

Daniel's stomach turned. Osiris. Why did he get the nauseating feeling that this had something to do with Kaitlyn's amulet? "I have."

"As have I," Kaitlyn added, looking a little worriedly at Daniel. It all seemed a little too coincidental that the amulet was Osiris and now this man, Jacob, was talking about him.

"Osiris was the god of the Afterlife," Daniel explained. "In power, he was second only to his father, Ra, and was the leader of the gods on earth. He was the husband of Isis and the father of Horus."

"This is sounding a little familiar…" O'Neill interjected.

"Osiris resided in the underworld as the lord of the dead, as after being killed by Set, even though he was a god, he could no longer dwell in the land of the living."

"I hate to tell you this, Dr Jackson, but Osiris is alive and well, though he is now a she, having taken a female host this time."

"Why does Osiris want to attack the Tau'ri, Jacob Carter?" Teal'c piped up.

Kaitlyn looked between Daniel and Jacob as well as the burly man with the tattoo. Osiris was alive? What did he mean he'd taken a host? And what the hell was a Tau'ri? Kaitlyn's head was spinning. There was something so not right here. She kept quiet though and listened.

"Apparently you have something she wants. I haven't heard any more but I wanted to come as quick as I could to warn you."

"Appreciate that, Jacob," O'Neill said.

Daniel and Kaitlyn exchanged a glance, both having a pretty good idea what it was that she wanted.

Sam picked up on the look that went between the pair, coming to the same realisation herself. "The amulet."

They nodded in unison.

"What's so special about this amulet?" Hammond asked.

Kaitlyn shrugged. "I'm not sure, sir, though I had an idea earlier that it may be some kind of key, simply for the fact there is no hole to string it onto a necklace, which was often the case with this style of piece. Sounds like she wants what's inside of whatever the key opens."

Hammond mulled this over. "Jacob, do you have any idea where this Osiris is now?"

"My sources tell me she's currently inhabiting a small planet called Kalnek."

"You have the address?"

"Yes, sir."

"OK, SG-1, I want you to check this out, providing the M.A.L.P doesn't send back any immediate signs of hostile action."

"Uh, sir? Request permission to bring Dr Richards along," Daniel asked hopefully.

"Absolutely not! I'm not authorising a civilian to venture into a potentially dangerous situation."

"With all due respect, sir," Daniel protested. "Kaitlyn brought the amulet to us. If it weren't for her, we wouldn't have a clue right now as to what Osiris might want."

"Be that as it may, Dr Jackson, I cannot knowingly allow anyone that is not part of the SGC to be subjected to the kinds of conditions that you're potentially going to come up against."

"Pardon me for interrupting, General," Kaitlyn interjected. "I certainly don't want to push my limits here…but if you're worried about me not being able to look after myself or slowing the team down…well I can assure you…that won't be an issue," she said quietly.

Several sets of eyes turned to look at her, the most surprised and confused being Daniel's.

"How so, Dr Richards?"

"I've uh, had fairly extensive martial arts training & a small amount of combat training. I've been in many training scenarios as well as several real-life scenarios."

Daniel's mouth dropped open slightly. OK, this was not something he expected.

O'Neill wasn't convinced. "And how is it that a female version of Daniel here has had so much martial arts and combat training, hmmm? Not exactly a pre-req in your line of work?" he sniped, raising his eyebrows.

Kaitlyn chewed her cheek and looked down at her shoes before looking back at O'Neill, eyes a little dark. She knew he was probably challenging her to protect her and his team, but she could do without the patronising "you're a female" tone. "Let's just say I had an interesting life growing up on the streets of London," she replied coldly.

Carter shot O'Neill a look.

O'Neill caught it and softened for a moment, pulling back his sarcasm to a serious tone. "Ever used a gun?"

"When I've had to," she said off-handedly. Truth was, she knew how to use a gun very well, though it was not something she was prepared to go into at that point.

Daniel was horrified. How was it this accomplished and talented woman, who held two doctorates to her name, was once a kid on the streets and had handled weapons? He himself had only picked up a gun upon joining the SGC. When he thought about it, there was probably a lot he didn't know about Kaitlyn and her past. It had never come up in conversation and he could see why.

O'Neill wasn't entirely convinced though he was starting to get the feeling that maybe Kaitlyn was more capable than he first thought, however he wanted to make sure. If she'd lived on the streets of London, it was very possible she'd used some sort of handgun. He walked over to one of the SFs and took his Beretta, removed the magazine and walked back over to Kaitlyn, handing her the two pieces. "I want you to put that together and shoot as close as you can to those two red marks on the wall over there."

"Jack, what the hell are you doing?" Daniel asked, becoming defensive.

"Colonel?" Hammond asked warningly.

"Sir, if Dr Richards wants to accompany SG-1 into a potentially hostile situation, I want to know that I'm not going to be babysitting and that my back is covered," he said bluntly.

Hammond didn't like it, but he had to admit, if the woman could handle herself, he'd be OK with letting her go. "Alright, Colonel," he agreed, before turning to Kaitlyn. "Dr Richards, if you can proficiently do what the Colonel asks, I'll authorise you to accompany them on this mission."

"Yes, sir," Kaitlyn said quietly, looking down at the pieces of the Beretta in her hands. It had been quite a while since she'd held a gun similar to this, though it was certainly not foreign to her. Kaitlyn slid the magazine into the holster until it clicked, then cocked the gun, all the while keeping her eyes on O'Neill.

O'Neill was impressed, though he certainly wasn't going to concede just yet. Not showing any change in expression, his eyes moved to the wall.

Kaitlyn held the gun out in front of her, taking aim, as the group dispersed behind her. She squinted one eye, keeping the targets in sight. She fired the gun at the first target before adjusting and firing at the second, smiling inwardly as she realised she had hit both. Slowly, Kaitlyn lowered the weapon to her side.

The group behind had a few raised eyebrows among them, some of admiration, some disbelief.

O'Neill strode over to the wall to check how close Kaitlyn had been to the two targets, knowing full well she had hit both. He pretended to inspect the shots before heading back to the group.

Kaitlyn gave O'Neill a wry smile as she released the magazine and handed the pieces back to him. "Was I close?" she asked innocently.

O'Neill looked at her with a new-found admiration. "Close enough."

Collecting himself, Hammond couldn't help but crack a smile. "OK, Dr Jackson, request to have Dr Richards accompany SG-1, granted." The woman may not have combat training but she sure as hell was a good shot! At least she wouldn't slow them down. "Major Carter?"

Carter's head snapped up then, shaking her out of her daze. "Yes, sir?"

"Take Dr Richards with you to get some more suitable clothing to wear. Alright, SG-1, gear up! Dismissed."

The team moved out, heading toward the locker room. Daniel grabbed Kaitlyn's arm as she turned to leave. "Kait, I uh, that was…I had no idea," he said, partly in awe, partly feeling sorry for what she had possibly been through.

"There's a lot you don't know about me, Daniel," she said quietly, a hint of sadness in her voice. She gave him a small smile before following Carter out. As much as she cared for Daniel, there were still feelings of resent toward him she hadn't dealt with.

Daniel looked around, a little embarrassed. "Yeah," he muttered quietly to her retreating back, feeling the sting of her words. He knew deep down she wasn't being cruel to be cruel, but there were definitely unresolved issues between them, though it was just going to have to wait.
