Little happened at Cheyenne Mountain that General Hammond didn't know about, so when the report from the armory crossed his desk that morning, he grabbed his phone and called the front gate to have Colonel O'Neill come directly to the general's office when he arrived.  Twenty minutes later, Jack leaned around the door frame, his hands occupied with carrying a miniature backpack and holding tightly to the tiny hand of his son, Danny.

"You wanted to see me, sir?"

Hammond gestured toward the armory report.  "You want to tell me why you requisitioned the use of a TER sweep on base yesterday and didn't inform me?"

Jack sat down in a chair across from the general's desk and pulled his sleepy ward into his lap.  "Danny was translating the writing on some doohickey Reynolds' team brought back, and I thought he was just doing his usual talking to himself thing.  I'd gone through two reports before I realized he was talking to someone, but when I looked up, there was no one there."

He shifted the child in his lap into a more comfortable position and continued, "I asked him who he was talking to, and he said Peter—"

"Petrie," Danny corrected.

"—And said that Petrie was helping him translate the text."

"You suspected an alien presence?"

"Yes, sir, and since you were stuck in a meeting, I made the call to have the level checked for uninvited guests."

Danny giggled.  "I told you, Daddy, he's invisible!"

Jack nodded and kissed his little boy's temple.  "Yes, Danny, but I still had to check.  Anyway, about that time, SG-8 came back hot, and I completely forgot about it until this morning."

A smile crossed Hammond's face.  "Danny, do you mind if I speak with your dad alone for a moment?"

The little boy rubbed at his eyes, shrugged, and gave Jack a kiss on the cheek before sliding off his lap.  "Petrie and I are going to go finish that translation, Daddy!" he announced, heaving his backpack off the floor and scampering out of the office.

"Sir?"

"Jack, did Charlie ever have an invisible friend?"

The colonel froze, then rubbed at his temples.  "Oy.  You know, we're all so used to the weirdness that happens around here, 'normal' is this last thing we look for any more."

Hammond chuckled.  "You want my advice, Jack?  Get that boy a dog."
