There was some sort of buzz in the air. Gaila was actually in a rush to attend Professor Spock's class.

"What's gotten you in a rush? I usually have to drag you here every day." Uhura said as Gaila lead her by the arm. Gaila stopped before the door and turned to Uhura. She squared her shoulders, lifted her chin and gave one of her best yet seductive smiles. "How do I look?" she asked.

Uhura, baffled, looked at her smiling roommate and said, "You look fine. Why are you so anxious?"

Galia winked while her smile remained in place. "You'll see."

There was a crowd of girls in front of Spock's desk. This was high unusual for this class. Curious, Uhura joined the crowd. Shoving her way to the front, she saw what the fuss was about. There was a man, an extremely handsome man sitting on the desk, smiling at all the cooing girls. His hair, dark and brown with lighter highlights was slicked back, slightly messy due to combing his fingers through it. His eyebrows were thick and he had traces of stubble along his jaw. His chestnut eyes were the first thing she noticed and then his lips. His voice sounded like velvet as he spoke. It reminded her of Spock which she now noticed was missing.

"Ahem, excuse me sir but where is Professor Spock?" Uhura asked in a tone that commanded attention.

"Ah Cadet Uhura! I have been waiting for you." The man said and hopped down from the desk. Uhura sucked in a breath as she took in his appearance once more. He wore white creased dress paints, a collared button up baby blue shirt, slightly unbuttoned to reveal a small tuft of chest hair, and a white form fitting blazer on top of it. He was also tall. Watching her eyes appraise him, he grinned, rendering her speechless. She blinked.

"Yes but where is Professor Spock?" She asked impatiently. The other girls stood behind the man now glaring at her because she took his full attention. She wasn't trying to on purpose but she had to admit, it was rather nice and she soon found her cheeks flushed.

"Ah Professor Spock. He's uh, taking some days off. I'll be teaching in his place." He replied to her. This was followed by excited giggles from the girls and fights about who gets seats in the front. Uhura panicked.

"But he never takes days off. Something must be wrong. I have to go find him and see if he's all right!" She said hurriedly and turned to make her way to the door. More like tried to for the man's hand gently stroked her cheek. He moved in closer to her face and she could feel the warmth of his breath. They seemed to be completely oblivious to the class and students around them.

"Are you worried about your dear Professor?" There was amusement in his voice. Uhura forgot to breathe as she stared into his eyes. She caught her breath and smacked his hand away which was enough contact he needed. His grin widened and flashed a wicked and knowing smile. Uhura shook her head not wanting to deal with whoever he was and decided to take a seat far in the back. Gaila, her roommate voiced her protests of this and abandoned Uhura to find a seat in front.

Sitting crossed armed, she watched as the new Professor spoke of Linguistics. Every girl in the class sat attentively hanging on his every word. Once again this was highly unusual for this class.

"More like his voice", Uhura thought with a scoff and rolled her eyes.

The Professor seemingly attuned to her voice stopped in mid sentence to address her. "Miss Uhura, is there a flaw in my lecture?"

There was that amused tone again. What was with this guy? He was smug, almost arrogant. It was as if he knew he was affecting her. Uhura crossed her legs to soothe the tingles that threatened to unravel her and glared at him. His lecture, she found was flawless. The only flaw as that it was not her favored Professor Spock delivering it.

The girls in the class all turned their heads to the back looking as if they would burn her at the stake if she dared spoke against him. Uhura rolled her eyes and quietly said "No Sir."

His eyes lingered on her for several long seconds before he continued his lecture. For the first time, Uhura contemplated on how to cut her favorite class. She needed to find Spock and stay away from this substitute Professor.
