25. Stumble

Spock sometimes wondered if he would ever understand humans as they often said or did things that seemed illogical. Dr. McCoy was a fine example this. The man was currently scolding their captain over his reckless behavior on his latest planet side adventure. His voice gruff and deep as lines tightened around his mouth and eyes. Yet it was those eyes that told a different story for they were warm, concerned and full of fondness. Why did humans act one way, but mean something entirely different?

"Hello Spock," a familiar voice chirped from his right. Turning his head, Spock gazed down at Harry who was walking past him with a tray of pills, water, what looked like soup and a hypo. The Vulcan nodded in salutation, his eyes never leaving the small doctor as he walked over to a patient, smiling warmly and greeting them gently.

"Sheesh Bones, what are you my mother?" Jim joked.

"Might as well be since you can't seem to take care of yourself," McCoy grumbled as he worked away on his PADD. Glancing over his shoulder he called out, "Harry, don't forget to that we need more vaccines shipped to us soon. Have either Nurse Chapel or yourself put in the order to Star Fleet."

"Okay Leonard," Harry called from where he was tending to his patient.

Jim tilted his head curiously, "Vaccines?"

"Yeah, been a nasty strain of the flu going around so I want to be prepared. So watch it Jim, we don't need you of all people getting sick. Not only would the ship be without a captain, but you're also a crappy patient," Bones ordered gruffly.

"Hey!"

Spock raised an eyebrow in amusement while they heard Harry giggle from where he stood. Even his patient tried to laugh although it quickly turned into harsh coughing although the raven haired wizard was quick to sooth him. Dark eyes watched as Harry helped the patient finish his soup before handing him the pills and water, green eyes soft with distress. The man offered a smile once he downed his medicine expressing his gratitude for Harry's care.

"You're always kind to us Dr. Black, we appreciate it," the man murmured softly. Harry smiled warmly making his eyes glitter as he replied, "It's my job. I have to make sure all of you are in good health." For a moment, as he observed the interaction between Harry and his patient, Spock could have sworn he saw his mother in that smile and it gave him such a strange, fluttering sensation in his side. It was confusing, but unfortunately not the first time such a sensation occurred around Harry.

Although Vulcans did not openly express emotions, Spock found that over time Harry was beginning to draw forth feelings that he only usually associated with Jim. It was quite illogical and perhaps troubling. After all, Jim was his T'hy'la while Harry was his friend. But as he watched the small doctor move around humming softly to himself while his head swayed to his tune, Spock thought it was endearing. And it certainly was refreshing to see Harry returning back to his normal self, the shadows in his eyes lingering less and less.

With his attention as divided as it was, Spock could honestly admit he was surprised by his reaction within the next moment. Harry had just picked up the tray from his patient's side and was turning to walk back the way he came before. As he was moving to pass Spock, the front of his boot dragged along the floor throwing off his balance and caused him to stumble.

"Ah!" he cried out dropping the tray in alarm.

Not knowing what compelled him, Spock lashed out and caught the young doctor pulling him to his chest. A startled squeak left Harry as he gripped the front of Spock's uniform to give himself a sense of balance, his face immediately flaring pink in embarrassment.

"Shit Harry, you okay?" Jim questioned in concern as McCoy knelt down to gather the items from the floor. Harry nodded as he turned his head to gaze at his captain, "Yeah I'm fine."

"You sure? You nearly made yourself acquainted with the floor there," Jim joked softly.

"Don't I know it. But I'm okay, just feel like my heart's about to jump out of my bloody chest," Harry grumbled before turning and gazing up at Spock with wide green eyes. His flush deepened a shade as he professed quietly, "Thanks Spock."

And for some reason, Spock could have sworn his own face and the tips of his ears heated up just a bit. Which was a peculiar reaction considering Spock had only ever blushed for Jim and even then that was rare. He would have to examine this phenomenon on a later date. But for now he merely nodded in reply to the gratitude directed to him and straightened Harry checking to see he was okay.

He didn't seem to notice Jim glancing between them in curiosity while McCoy glanced between all three of them before looking at the ceiling in exasperation. All Spock could seem to focus on was the soft flush on Harry's cheeks and the shy smile on his lips. Things were certainly becoming interesting it seemed and Spock wasn't sure if it was a good thing or not.

Please review! Thanks!
