**If you comment a request, please tag me in it. Wattpad isn't notifying me with comments, so I don't know until I look which is usually a couple days later. And requests are closed for a little while, I'm stressed and overwhelmed (not by requests, well, maybe a little by requests) but by other things in my life. Added stress isn't good. I will get them done, I just don't need more and more from requests. Thanks and they will be open in a week or so. I will do the ones I have now though.

Its already 3 years into the five year mission. Chekov is 20.*

Being the sister of a half Vulcan can be horrible. You were adopted and you were human, very different then your brother Spock. You were a few years younger, making you twenty two.

"Y/N, can you hand me the sulfur?" Spock asked, holding his hand out. His eyes never moved from the microscope lens, always watching.

The two of you were working on an experiment, testing micro-organisms under different chemicals and matters. Sulfur was next on the list. Spock's hands were steadier when it came to possibly torturing organisms, so he would be putting sulfur into the clear tray.

You watched as the organisms squirmed and tried to wriggle away from the powder. One was buried by the dust, probably dead by now. The few others were climbing each other to get away, but they couldn't.

"Awe, Spock. They died." You mumble, watching as they all grew very still.

"They do not enjoy the sulfur. And it kills them." Spock noted on a PADD. "What should we test now?" He asked, getting a new tray of organisms.

"Spock, I don't want to do this anymore today." You mumble, staring down at the dead organism through the microscope.

"Why not? Because they died?" Spock asked, setting down the new tray.

"Yeah, I don't like watching them die." You mutter, feeling childish. It was childish to be scared and hurt by watching something die, but for some reason you felt terrible for the little living creatures.

"That is understandable. You are my sister, adopted sister, but I don't like seeing hurt. Or anyone for that matter. Take the day off, I can handle it here." Spock said, taking the tray of dead ones and setting it on the counter. "Get some rest."

"Thanks Spock. You're a good brother." You say, giving him a hug before leaving.

Slumped shoulders, you walked through the halls. "Y/N?" A familiar voice asked, jogging up beside you.

"Hey Pavel." You mumble, acknowledging the Russian beside you.

"What is wrong?" Pavel asked, concern filling his face.

"Work just upset me." You mutter, walking into an observation deck. Just your luck, it was empty.

"Why did it upset you?" Pavel asked, motioning for you to sit on the couch. Sighing, you did. Before continuing, Pavel brought over some tea.

"We had to test these organisms for their reactions to various chemicals. I just couldn't watch them die and suffer." You say, shaking from being upset.

"Awe, it's alright. That shows you have a kind heart, I like that." Pavel said, smiling. He wrapped his arm around you, setting his tea in the table.

"Thanks. Those poor organisms though." You mutter, snuggling closer to him.

"Yeah, it's sad. But, if it makes you feel better, the organisms you use don't feel pain and don't know the difference between life and death. As far as they are concerned, it's just another normal day." Pavel reassured, kissing the top of your head. Both of you had been close friends for three years, but never more. Maybe now that would change.
