A/N: This story is sorta a sequel to two of my prevous fics, Fallen Star and Postcard. However all three can stand alone. I don't own Doctor Who. Feedback is appreciated. Enjoy! :D

It wasn't often Rory got to explore the Tardis alone. He was always with either Amy or the Doctor, but he did like these quiet strolls alone. Rory was quite deep in the time machine when he noticed an open door at the end of the hallway. That's strange Rory thought. All the other doors in this hall are locked. Why should this one be open?

Letting his curiosity get the better of him, he walked inside. It looked like a bedroom of some kind. It wasn't well-kept, clothes were everywhere. The only clean area was a desk, which had tin canisters on it, kind of like those used for hairspray. A bomber jacket was flung over the chair. It had all sorts of patches and pins on it, and the word 'Ace' adorned the back. Rory picked up one of the cans and the jacket. Maybe, he thought, if I show these to the Doctor, he could tell me whose room that was. With that, he ran off to find his wife and the Doctor.

He found them in the console room, and by the time he got there he was out of breath. Amy was the first to notice him.

"Rory, where have you been? You're all out of breath!"

"I found- I found something. I was wondering if- if the Doctor could- could tell me, whew," Rory panted.

"Well, Rory," said Amy, smirking. "It looks like a jacket and a can of deodorant."

"What!?" the Doctor looked up, startled. He saw the can in Rory's hand. "Be careful with that!"

"Doctor, calm down!" cried Amy, confused by the Doctor's behavior. "It's not going to explode!"

"Right?" Rory asked, nervously.

The words of an old friend echoed through the time lord's head. Do you feel like arguing with a can of deodorant that registers nine on the Richter scale?

Rorycleared his throat. "Doctor," he began, "what's in the can."

"Nitro-9."

"What?"

"Hmm? Oh, it's an explosive an old friend of mine makes."

"You had a friend who made explosives?" Amy didn't sound convinced

"Yup, her name was Dorothy McShane, but everyone called her Ace."

"That's the name on the jacket," said Rory.

"So it is. I should probably give that back. She left it in her room years ago."

Amy's mind was spinning. Ace. She heard that name before, but where? Then, it clicked in her mind.

"Doctor, was that the name Mel wrote on her postcard?"

"The very same."

Suddenly the Tardis lurched.

"What was that!?" Amy shrieked.

"Oh, we're just making a quick stop on Earth in the early 90's. I'm going to mail Ace her jacket.

"Why not just give it to her in person?" Rory asked.

The Doctor's grin faltered a bit. "She wouldn't recognize me. I've changed so much since I last saw her. She won't need her Professor anymore."

Amy and Rory exchanged glances as the Doctor carried on with his task. He would be forever an enigma to them, but maybe one day they would get him to open up. Maybe tell them about the travelers before them. But until then, they would keep exploring. Amy already learned about Adric's sacrifice and the promise Mel kept. Who knew what they find out next?
