Author's note: So, this is pretty much a continuation of the Happy Birthday, Jack story, but it's a few weeks later, and everything's back to normal (as much as it gets, anyways) I'm not sure how long it will be, but we'll wait and see how things unfold!

Disclaimer: I don't own Jack, Sam, Jacob or any of the SG characters that are already made up, but I do own Jaffer (Thank goodness, because I really love writing him)

...................

The street was dark. One of the streetlights that normally illuminated the road was malfunctioning and the other one just wasn't enough to make up for the loss of the broken one. A non-descript sedan drove down the dark street and stopped in front of one of the many dark houses on the street. A moment later a shadowy figure emerged from the car and looked around.

The house was as dark as the street it was on. The porch light, which normally was on at night, had been forgotten and whoever lived in the house had left only one small night-light on in the kitchen, which barely showed through the open curtain of the living room.

Silently, the man from the car walked up to the front door. He looked under the welcome mat, thinking that there might be a spare key hidden there – lots of people hid spare keys there, after all. When he didn't see one, he looked under a nearby flowerpot but there wasn't one there, either. Grumbling, he gave up, and with a faint tinkling sound, he pulled put a set of lock picks from his pocket.

The noise of the lock clicking open a moment later seemed deafening in the quiet of the neighborhood, but it was his imagination, he knew. Nothing heard the lock clicking open, and no one heard the faint creak of the door as he swung it open a moment later.

He was wrong.

He'd barely moved into the hall and closed the door silently behind him when he heard a very faint noise. A slight clicking sound, like a bird clacking its beak, or the sound of claws on tile, perhaps. Whatever it was, it didn't repeat, no matter how hard the man listened, so he assumed it must have been his imagination.

Then he saw a slight movement. A shadow moving against the shadows thrown by the tiny night-light in the other room. This he was sure he saw, but again, he had to be imagining it, since he knew the house well and knew that nothing that big and dark lived there. He started to take a step forward, and the shadow moved once more. This time it was moving towards him, and he froze, knowing that whatever it was, it definitely wasn't his imagination.

A low, almost inaudible growl was the only warning he had. A second later, the shadow had solidified and had launched itself at him. With a shout of surprise, the man went down, landing hard on his back with the heavy weight of whatever it was fully on his chest. He started to struggle, but felt something clamp on his throat, and he stilled immediately.

There was a faint rustle of clothing, and the sound of bare feet moving on carpet, and then the room was suddenly washed in a bright light as a switch was thrown on.

"Dad!"

Samantha Carter rushed over to the entrance hall, where Jaffer was sprawled on Jacob Carter's chest, his teeth locked firmly on the Tok'ra's throat.

"Jaffer! Let him up."

There was another low growl, and Jacob saw the brown eyes go from watching him suspiciously to looking over at Sam. Still his teeth didn't move and his jaw didn't relax.

"Jaffer, drop him baby. It's okay."

There was a sigh, that Jacob felt more than heard, and the teeth loosened their grip on his neck, then the big black lab got off him, and walked over to stand next to Sam, his head still low as he watched his prey.

Sam brought her hand down onto the lab's head, rubbing his ears to relax him.

"It's okay, Jaffer. You know my dad."

Sure he knew her dad. But her dad wasn't supposed to be sneaking into her house in the middle of the night. People you know come through the front door with the lights on, not sneaking around like they're up to no good. Jaffer still watched Jacob suspiciously, and moved when Sam started to reach down to help Jacob to his feet. He stepped between the Tok'ra and his charge, unwilling to trust that all was well just yet.

With a scowl, Jacob got to his feet and glared at the dog while he ran his fingers along his throat, certain he was probably bleeding from half a dozen serious gashes, no matter that Selmac was telling him he was fine.

"What's he doing here?" Jacob asked, glaring at Sam as if it were all her fault, now. "George said Jack was out of town."

"He is." Sam said, kneeling down and putting her arms around Jaffer, still trying to relax the black lab. She could tell he wasn't exactly sure Jacob wasn't up to no good, just by the way he made sure to keep himself between her and him, which wouldn't do, since Sam wanted to give him a hug. "But he left in an F-15, and he couldn't take Jaffer, so he's staying with me. To keep me company." Uh huh. That was only part of it, and Sam hadn't been fooled at all. Jaffer was also her personal guard dog while O'Neill was gone, and she knew that he knew it as well as she did. Hence the extra protectiveness. "You shouldn't have been sneaking around in the middle of the night." She said, stroking Jaffer's side, again, but smiling. "He could have killed you."

Well, no, probably not. Jaffer could be vicious when roused, but he'd reacted exactly as he'd been trained, and she knew her father wouldn't even have a mark on his neck. But it was fun to say. Especially when it made him scowl like that.

"I didn't know he was here, or I would have knocked." Jacob sighed, and knelt down, reaching a hand out to Jaffer. He didn't like the suspicious look in the black lab's eyes, and wanted to remind the dog that they were friends. He just didn't come around as often as everyone else did. Jaffer reached his nose out and sniffed Jacob's hand. He didn't want to be suspicious of the Tok'ra – he liked pretty much everyone, after all – he just didn't like people who did sneaky things. Especially when he was in charge of the house, and the occupants.

"What are you doing here?" Sam asked, smiling when Jaffer's tail began to wag idly, as the dog accepted that Jacob wasn't so bad, after all.

"Came for a surprise visit." Jacob said, rubbing Jaffer's ears. He grinned, realizing that the surprise had been all his. "Surprise."
