Isaac knew. He knew it from the moment he laid his eyes on him.
"Name's Isaac. What's yours big guy?"
He only wanted a taste of that fruit. Just a taste. So lustrous and sweet smelling that it was bound to be poisoned.
"Samuel Ortez...but you may call me Sam."
And his voice. Oh his voice. Deep, husky, smoky. Try as he might, he couldn't stop his knees from becoming weak. And then he whispered. "It'll be easier for you to scream."
Sam told him he was drafted as well, but Isaac knew he was lying. He knew it, but he wanted the apple so bad. He could...he SHOULD wait until a less rotten apple came by.
He didn't last three days.
"SAM!" Sam ruined him. Isaac would never be able to sleep with another man without feeling unsatisfied. One small bite was all it took. So divine tasting, and he couldn't put it down. Alarms rang in his head. Instinct ran rampant in his mind. But he didn't care. The apple was too rich in taste it had him hooked.
It was all a blur. One moment they had their team, their troop, their squad. The next, they were the only ones alive. Sam didn't care...or at least it looked like it. Isaac...Isaac was scared. What will happen now? An alien could pop out at any moment and be done with them.
"Don't worry Isaac...I'm still here. We'll be fine. We'll leave this place. Together."
Isaac knew. Isaac knew it was a trap, but he already had one bite of the poisoned apple. Nothing happened, so what's one more going to do?
The next mistake he did was seeking comfort in Sam, and Sam gave it. A kiss here, a touch there, hips meeting other softly, gently and Isaac tangled himself deeper.
"The UNSC will be looking for us. Choose a new name and change your armor. From now on, call me Locus in public. In private," a careful a caress to the cheek, " you can call me Sam."
And so Felix was born, but on that same day Isaac knew he would never be able to get out. Locus had finally caught him.
