Jack didn't say much of anything on the way back to the SGC. He'd handed Sam his keys as they'd left the Adams' house, telling her that she'd better drive. Which meant that he knew he was too distracted to be behind the wheel. She didn't argue with him, and as the silence between them grew deep, she didn't press him to start a conversation. She knew when he was ready to discuss it with her – once he'd thought it out himself – he would.

She looked over at him more than once, usually just when she had to look his way anyways, like to check for oncoming traffic. His position didn't change. He was leaning slightly against the passenger door, the side of his head pressed against the glass as he stared forward out the front window. She was pretty sure he wasn't actually looking at anything, though, since his expression was about as distant as she'd ever seen it. He was thinking, she knew, and she could understand. He'd had quite a day, and there was plenty for him to think about.

Sam reached her free hand out and placed it gently on his thigh. She didn't look at him, or say anything, and when he looked over to see if it was a way of getting his attention, he saw that she didn't want anything from him. She was just giving him what little support she thought she could. Jack rested his own hand over hers, acknowledging the touch silently, and resumed his brooding.

The door to the infirmary opened and Fraiser walked in. Daniel looked up from the necklace he'd been looking at and smiled when he saw who it was.

"Are you still trying to figure that thing out?" Janet asked him, shaking her head.

"Nah. Just looking at it." He gestured over to the sleeping man. "He woke up. Well, kinda. I don't think he was very aware of what was going on around him, or where he was. And he wasn't awake long."

"Did he say anything?"

"He asked what happened. He knew me, Janet. Recognized me and asked for Jack. It is Shawn."

"I told you it-"

"I know. But being told and believing are two different things." Daniel grinned and held up the necklace, looking around to make sure no one else was around. "I asked him where he got this."

"You pestered him?"

"No, no. It wasn't like that. He asked me where I got it, first, and I... well... yeah, I pestered him. A little."

"So? Did he tell you?"

"He told me Jacob gave it to him."

"Jacob Carter? Sam's dad?"

"That's what I asked." Daniel smiled. "Know what he said? He said he got it from Jacob O'Neill. And that I'd been there."

"I don't know any Jacob O'Neill, Daniel." Fraiser said, her brow furrowed as she tried to remember if Colonel O'Neill had a male relative she'd forgotten about.

"He's from the future, Janet," Daniel said. "Maybe there isn't a Jacob O'Neill here, but there is there?"

Her eyes widened as she realized what he was getting at, and she smiled as well, looking at the necklace.

"I didn't think of that. Are you going to tell the Colonel?"

"Nope. I had to tell someone, though."

"Yeah."

She thought about that for a moment. "I'm not going to say anything, either. Why ruin any potential surprises? But it is nice to think about, isn't it?"

"Yeah."

They heard a whine outside the door, and Daniel and Janet crossed the room and opened it, looking at Teal'c, who was still standing there, leaning slightly against the wall with the two dogs near at hand. Jaffer whined again, looking over at Daniel when the door opened, then down the corridor, his tail wagging idly.

"Why's he doing that?" Janet asked.

"O'Neill must be returning."

Sure enough, a moment later Jack and Sam both turned the corner, and Jaffer gave a low woof and broke ranks to thunder down the corridor at a full run towards Jack.

People dodged him, mainly because that was a lot of dog coming at them and it was safer to move than try to contain him, and Jack was pulled out of his inner thoughts when he saw the large black shape coming at him. No one could brood when a lab was around. Especially when he was so happy to see you that his tail was wagging a mile a minute. He stopped and dropped to a knee, bracing himself, and Jaffer put on the brakes far too late for the slick concrete floor. As Jack had known from experience that he would. A hundred pounds of dog crashed into him, and the Colonel caught him easily, halting the momentum with careful arms that he wrapped around the big head.

"Hey! There's my boy!" Jack ignored Sam's amused grin, and rubbed his dog's ears cheerfully. Then did the same for his namesake when Teal'c's yellow lab decided he needed attention, too, and broke down the hall as well, although he didn't have any trouble stopping.

With Sam on one side, and Jaffer on the other, and Jack leading them all back to the door to the infirmary, Jack walked over to Teal'c, Daniel and Janet, looking towards the door.

"How's he doing?"

"He's resting, Colonel." Fraiser said.

"Were you able to locate the whereabouts of Shawn Adams, O'Neill?" Teal'c asked, reaching down despite himself, and scratching Jack's yellow ears when the lab came over to get some attention.

"Yeah, he's up in the mountains fishing with his... with James."

"And Dotty?" Daniel asked.

"Oh, Dotty is not all that she appears to be," Jack said, taking a deep breath. "We need to talk to Hammond, and you guys might as well hear this, too, so Sam doesn't have to repeat it."

"Me?" Sam asked.

"I only understood about a quarter of it, Carter," Jack said. "You were paying attention, right?"

"Yes. Of course."

"Well, there ya go." He shrugged as if it made all the sense in the world, and headed down the hall, Jaffer ambling beside him. "Teal'c, put a couple Marines on the infirmary door, will you?" Jack called over his shoulder. "I want them armed with zats."

"What's going on?" Daniel asked Sam, who watched with the others as Jack vanished around the next corner.

"Oh, it's complicated, Daniel," Sam said, shaking her head. "Come on, let's go get General Hammond, and then you can all hear at the same time. I don't want to have to repeat this one any more times than I have to."
