Long Preference - He Gets Jealous

"This is (Y/N), my partner. (Y/N), this is the one and only Anthony Mackie," he introduced the two of you. You grinned and held out a hand for Anthony to shake.

"It's great to meet you, Anthony," you greeted. He took your hand and shook it, his hand lingering a bit on yours. It wasn't anything extreme, but it was enough for Sebastian to tighten his grip on you a bit.

"The pleasure is all mine, (Y/N). I've heard so much about you, it's great to finally put a face to a name. Especially when it's a face like yours," he flirted with a wink. You had to forcefully stifle your laughter at his awful pickup lines, but Sebastian didn't seem to find it very funny. You knew that Anthony was only joking, as that's just how he acts, but the blue eyed man next to you didn't seem to care about that.

"Alright Anthony, come on," Sebastian muttered, a clearly annoyed undertone to his seemingly joking words. Anthony raised an eyebrow and smirked, realizing that he had struck a nerve.

"Oh, somebody's jealous!" Anthony called, clapping his hands together. "Scared I'm going to swoop in and steal your girl?"

You couldn't help but laugh at this, but you saw Sebastian's jaw clench a bit at his words. Anthony was quick to change the subject, which allowed Sebastian to relax a bit, but he never removed his arm from around you. He kept you pressed close against him, as if he thought Anthony was going to literally grab you away from him.

When Anthony was grabbed by one of the interviewers that was looking for him, you took your chance to spin around and put your hands against Sebastian's chest. He looked down at you and placed his hands on your waist instinctively, his head tilting ever so slightly in confusion.

"What's wrong?" He asked worriedly. You chuckled.

"You know I'd never leave you for Anthony, right?"

Sebastian sighed lightly and grabbed one of your hands in his own, his fingertips trailing lightly over the creases in your palm before he pulled your hand up to his lips and planted a kiss on the back of it. "I know, but I also know what he's like. I don't like watching him trying to make a move on you, whether it's jokingly or not..." He admitted. You smiled softly at him.

"I know you don't, but sometimes you have to let it go. You know he'd never really try to steal me away, he would never do that to you. Plus, even if he did, it's no use if I'm not interested."

He lifted his gaze from your hands up to your eyes. A few strands of hair fell in front of his face as he did so. "How do I know you're not interested?"

You brushed the hair out of his face and allowed your eyes to wander over the features you knew well enough that you could draw them in your sleep. "Because I already have the only guy I want right in front of me, and he's got much better pickup lines."

Chris Beck

Chris wasn't one to get jealous easily. He was a pretty confident guy in many aspects, and your relationship wasn't an exception. He trusted you more than he trusted anyone on the Ares III crew, and he didn't hide it. So when he blasted off towards an unknown planet, not to return for a good while, neither of you expected an issue to surface.

Throughout the majority of the mission, things went swimmingly. You communicated every once in a while through emails and little video messages, and though it wasn't much, it was enough. You both just needed the reassurance that the other was okay every once in a while, and that you would be seeing each other soon. It wasn't until after the crew had circled back around to rescue Watney and they were returning once again that you hit a bit of a bump in the road.

Chris stared menacingly at his newest message from you. His arms were crossed over his chest and an irritated scowl rested on his lips. It wasn't that he wasn't happy to hear from you, he just couldn't get over the end of your message.
