Chameleon Circuit

Rory Williams was walking through the grocery store, picking up bananas and some frosting for their son, Gregory's, third birthday cake.

He took a step back as he was about to leave an aisle, and bumped into someone.

"Oh," he apologised, "Excuse me, Si... Oh no."

"Rory!" the bow-tie clad geek greeted, happily, hugging him, "How are you and Amelia? You still have that car."

"Hello, Doctor," Rory sighed, "No. I'm afraid it wasn't... Efficient for our family since..."

"Since?" the Doctor raised an eyebrow, when he trailed off.

"Since... The birth of our son, Gregory," Rory managed, wincing as the Doctor started to get all excited.

"Oh! Little Ponds! How sweet!" the Doctor cooed, "When do they get to meet Uncle Doctor... Or... I suppose I'm his brother, aren't I?"

"Yes, well," Rory rubbed his neck, "Doctor... Um... Have you seen Melody, recently? How is she?"

"She's well," the Doctor promised, "She misses you very much. If you like I cou-"

"No," Rory held up his hand, "That's quite alright."

"Oh, well..." the Doctor muttered, "Rory. Is it just me or are you less than happy to see me?"

"It's great to see you, Doctor," Rory insisted, "Don't get me wrong, but I'm just thinking of my family at the moment. I... Don't want to involve Gregory in your world, too. Amy was already broken when we lost Melody, but if we lose him as well..."

"No," the Doctor nodded, "I understand. Perhaps... It'll be best if I left."

"Oh... Doctor, wait!" Rory called after him, guiltily, "I suppose it won't hurt to spend one evening with us. It's Gregory's third birthday, you know. He'll be so glad to meet you. He like's new people."

"Hurray!" the Doctor sang, happily, "If I may, though, why Gregory?"

"Gregory Pond," Rory explained, "You know... GP? General Practitioner?"

"Oh, well," he actually blushed, which made Rory chuckle, "Did Amy come up with that?"

"Nope," Rory shook his head, "She wanted to just name him 'Doctor' and I said that would raise suspicion. So, I came up with that, to compromise. She loved it; said he could be our secret little Doctor. He's already found my bow-tie stash three times. I can not hide it from that kid."

"I... I'll meet you back at your house!" the Doctor promised, "I've got to get something for him!"

"No Fezes!" Rory warned.

"No promises!" the Doctor called back, disappearing around the corner.
