A/N: I just watched the first 4 episodes of Alphas, and this sprung into my mind! Doesn't have to be read with my other Rose/10.5 fic. I just love writing for these two so much because they are a real couple, and I want a go at the Alpha characters. Might unblock some things with my other fics.

"New York City! Smell that Atlantic breeze, Rose! I took Martha to New York City back in our universe. The year was 1930, and it turns our good friends the Cult of Skaro were - Hello what's that about?"

Rose was just stepping out of the TARDIS when she saw the Doctor's head swiveling to follow a man running very fast in front of them, followed almost at once by a larger man.

"No matter what universe we're in, you still manage to land us right in the middle of somethin', don't ya?" Rose put on a mock frown that didn't fool him for a second. It turned into a grin.

Without another word, they clasped hands and took off after them.

The chase ended at what looked like a police barricade, where the large man had tackled his quarry to the ground. Rose turned to leave.

"Looks like just normal police stuff, Doctor. You promise to take me to a Broadway show, come on." She tugged on his hand, but his eyes were on the crowd behind the barricade.

Rose followed his gaze. At the front was an older man with grey hair talking to a few suits, Rose guessed CIA or FBI. Next to him were two women, one tall and clearly well off, the other shorter and more reserved. A few steps behind, and the object of the Doctor's clear interest, was a young man, not much younger or older than Rose, who seemed clearly unfazed by the whole situation. In fact, he was facing a whole other direction entirely. The oddest part, though, was his hands, which were swiping and twitching sporadically in front of his face. Rose figured he probably had a condition or something, like Autism. But she couldn't understand the Doctor's specific interest.

The Doctor turned to her, grinned his Doctor-ish grin, let go of her hand, and walked towards to barricade, the psychic paper already pulled out of his pocket. His disarming grin had made Rose hesitate so she couldn't stop him, which was the intent. Oh, this could get interesting, she thought.

The Doctor had already made it to the barricade when Rose caught up with him. The two women were looking at him like he was crazy, something Rose was quite used to by now.

"Doctor-"

"Oh, this is brilliant Rose! He can see wavelengths from radios and electronic devices and scan them! I've heard of this before, happens in the part of the brain that-"

Rose nudged him into silence as the older man walked over, looking protective and a little in awe.

"How in heaven's name did you know that?"

Rose intervened before the Doctor could answer, "I'm sorry, he does this. We're just tourists, lost our way looking for Chinatown, but we really should be going, come on Doctor." She yanked on his hand, but he wouldn't budge.

"No, Rose, you don't get it! I heard about this in the, you know," she nodded for him to continue, "they're called Alphas, apparently, and it seems they are put to the same use here, finding others like them for the government." He said this in a stage whisper, and Rose groaned as the group in front of them took on another familiar tone of anger and frustration at this stranger.

"I'm right, aren't I?" He looked around at them, the smaller girl nodding her head in a daze.

"They're the source."

This came from the young man who had caught the Doctor's attention in the first place.

"What source, Gary?" The taller woman asked.

"The source I told you about, the wavelength I haven't seen before."

The older man turned his gaze on the Doctor again, and said, "I think you two better come with me." He beckoned to the group around him, and the Doctor turned to grin at Rose again, who just rolled her eyes. "Ok, fine, but if Torchwood gets pissed again I'm blaming you." He grinned wider and pulled her along, following to the group.

A/N: Sorry it's not that long, I'll try and make the following chapters longer! Review, I want to know how I'm doing with such new characters!
