"Hello, Y/N. How are you today?" Pavel Chekov asked, sitting next to you at a lunch table.

"I'm alright. You?" You ask, taking a bite of your sandwich.

"Great. I have a quick question." Pavel stated, looking at your eyes.

"Pavel, before you ask anything that you might regret, just know that my brother is really over protective." You say, looking back at him.

"I'm still going to ask. Will you go out with me?" He said, stuttering and blushing at the end.

"Pavel, I would love to. But once again, I'm warning you about my brother. He will hurt you." You reply, starting to smile.

"It'll be fine. Who's your brother?" He asked, taking a bite of his sandwich.

"James Kirk." You reply. Pavel spit out his sandwich and choked a little.

"The Captain is your brother! Oh man I'm screwed if I hurt you." Pavel exclaimed, wiping his face.

"I'll tell him. It might make things go easier." You say, patting his shoulder.

"I'll give you details later. I have to go do something." He said, leaving.

Later that night, you were having dinner with your brother in your quarters.

"How was your day?" You ask, trying to be as pleasant as you possibly could.

"Stressful, as usual. But you know I love it. I also love being able to look forward to a dinner with my sister, as long as neither of us have a date." Jim said, glancing at you.

"Speaking of dates, I have one." You say, looking down at your food.

"What! Who?" He yelled, slamming his food down.

"Jim calm down. It's just Pavel Chekov, you know him." You reply. Jim slowly sat down and angrily went back to eating.

"Your lucky I like embarrassing people." He muttered, stuffing some chicken into his mouth.

The next day, Pavel Chekov was sitting at his station. When the Captain walked up to him, he knew he was in trouble.

"So, Ensign Chekov, I heard you asked my sister out on a date." Kirk said, moving closer to him.

"Yes sir." He answered, working on a report at his control station.

"I'm going to go over a few rules since we've never had a father." Kirk began, taking the PADD from Chekov so he couldn't work. "Don't you dare hurt her. Anything you do to her I'll do to you. No sneaking around. You can be alone, I trust that you won't do anything. And please don't kiss in front of me or else I will hurt you."

"Yes sir." Chekov said, blushing red. Uhura was giggling at her station. Sulu was grinning, and McCoy was trying to stop laughing. Spock even looked slightly amused.

"When's your first date?" Uhura asked.

"I'm thinking Saturday night. Have dinner." Chekov answered, taking the PADD back from Kirk.

"Don't hurt her." Kirk said, doing the 'I'm watching you' symbol with his hands.

I'm in for a wild ride. Chekov thought going back to work.
