As Spock walked down the hallways of Starfleet headquarters flanked by James Tiberius Kirk, his boyfriend, and Doctor Leonard Horatio McCoy, Jim's best friend, he sighed. His father had suggested a Vulcan-style mourning ceremony for his mother but after some thought Spock declined: a mourning ceremony would have to take place on the colony planet, a human funeral or a memorial would be more logical as his mother's human relatives may also take part. He had underestimated the task in preparing the memorial.

The meeting went well; he had been given a list of his mother's relatives and would peruse them in his apartment. Despite Spock's insistance he was fine and the fact that Jim had another apartment across the complex he still slept over every night.

As Jim placed the cup of tea, steam rising, on the coffee table Spock frowned. "What is it baby?" Spock looked at him disapprovingly.

"I have already informed you that I am not an infant. Please refrain from using that term." Spock took a breath. "There is something that doesn't make sense in my mother's family tree. It states that there is another son."

"So, what does that mean? Do you have a brother?" Jim sat on the couch next to him.

"Not a full one. I shall do a search." Spock got up and typed in the name into the computer. "Fascinating." He mused. "It seems my Elder half brother works for the Univeral Bureau of Investigation, which was..." "formally the FBI!" Jim interjected, becoming very excited.

"Yes, he was also the youngest on his team and, according to the interview on this page he has an IQ of 187, an eidetic memory and can read 20,000 words per minute." looking over at his boyfriend he continued. "By human standards that is considered a genius, however had he been Vulcan he would've appeared to be just another Vulcan."

Jim smiled "Maybe not all your brains came from your Vulcan ancestry." He glanced over at the chronometer on the mantlepiece. "It's late, we need to rest. Out of curiosity what do you want to be called?"

"Ashayam is the most popular term of endearment on Vulcan. T'hy'la however would better describe our relationship." Spock wrapped his arms around Jim.

"Okay, Ashayam it is. I don't think I could pronounce the other word." Jim sighed, then yawned.

"Very Well T'hy'la. I shall take my rest at your side and in the morning I shall inform my half brother of his mother's funeral." And with that Spock and Jim headed to bed.

Jim patted the other side of the bed in confusion: he was sure he went to bed next to a warm and hunky Vulcan. "Ashayam?" he sits up, then gets up and goes into the living room, where he finds Spock calling his brother.

"Yes, that will be amenable. My partner and I shall meet you in Las Vegas in due course. Live Long and Prosper." After Spock gave his traditional greeting he turned off the communicatior and went into the kitchen. "I made us some breakfast. Oatmeal."

After breakfast Jim booked them tickets on the next shuttle to Las Vegas, grateful for the 15 minutes flight time. He packs a toothbrush for each of them, some pyjamas and a change of clothes each.

"You ready sweetheart?" Spock gave one sharp nod and they headed into their hovercar.

In Las Vegas Spencer Ried closed his communicator and headed back to the team.

"Hey Pretty Boy!" his best friend Derek Morgan shouted at him. "What was that all about?"

Spencer shrugged "I don't know. Starfleet wants to talk to me." Morgan put his arms around Spencer's shoulder.

"Well if it's Starfleet then it must be important. Don't worry, it's probably just a consultation." Technically Morgan wasn't lying: Starfleet did take consultations from the UBI's Behavioral Analysis Unit but Spencer sensed it ran deeper than that. Fortunately there was a case to keep his mind occupied and the Vulcan he spoke to would be here in a few hours. He threw himself into his work.

Stepping off of the shuttle Spock was first struck by how grand it all seemed; there were minatures of the Eiffel Tower and the Statue of Liberty and there was a hotel called "Caeser's Palace". It didn't seem right for the Vulcan at all.

"Ahhh, Vegas!" Jim smiled and inhaled deeply. "Maybe I can gamble when I'm here." he says rather amused. Spock sighs and intones " I do not think that would be wise T'hy'la, the odds of you winning are..." Spock is stopped in his tracks when Jim laughs heartily. "I was kidding Spock."

Raising his eyebrow Spock gets in their taxi and gives the driver the address of their hotel. In a few hours he would be meeting his brother for the first time.

A/N: Okay, I am in the middle of another chapter for my ongoing fics but the plot bunny for this one wouldn't leave me alone so I had to write it!

I have been so busy over the past few...years...has it really been years?! Wow! Oh well I'm back and I'm ready to write fics!
