So I've been getting a lot of questions regarding whether or not this is a RiRen or EreRi fic. This particular piece is RiRen, only because I can't really stomach EreRi. The thought of Eren topping confuses me a bit. I'm really sorry if any of you were looking forward to EreRi. However, if I'm feeling generous once this multi-part fic is over, then I might be willing to write a EreRi drabble since so many of you prefer that. Let me know what you think about that and I hope you enjoy this chapter!

A slow, steady beating echoed in the former corporal's ears. He at first thought it was the younger male sleeping against his bare chest, but then there were two sets. Suddenly, feeling a bit protective over the young vampire, he shot out of bed and raced outside, the sunlight almost blinding him. The heartbeat was a bit of ways away from their small cluster of homes, but a bit too close for comfort.

He approached the human carefully, using the trees as cover. But when he saw who it was, he flinched and hissed. The blond male heard the other, stiffening.

"Rivaille?" His voice was a bit different than he remembered, but it still pissed him off and made him feel disgusting. The shorter male hopped down from the trees, standing in front of the man and his horse. He couldn't hear any heartbeats nearby, so he assumed the man came alone.

"What the fuck ya want?" Rivaille hissed, crossing his arms over his chest. Irwin stepped down from his horse and tried to approach the male, but was met with a cold and icy glare, sending a shiver up his spine.

"I came to warn you. It's the least I can do." Rivaille snorted.

"Ya think that can help erase what ya did t' me? Think again, asswipe." Irwin's face was twisted on confusion.

"Rivaille, what are you talking about?" That only made the vampire angrier.

"So ya think ya can just fuck me and forget abou' it days later? I'm callin' out your bullshit." Irwin's face turned pale and he froze in place. Rivaille noticed the misstep in the other's heartbeat. He stood there, looking almost like a corpse. "Oi, what tha fuck is wrong with ya?"

The blond only shook his head. He took a few deep breaths before turning to the raven with a saddened expression.

"I was hoping I wouldn't have to tell you, but it looks like I have no choice now." Rivaille blinked. "Seeing as how he already got to you, I might as well come clean."

"Huh?"

Irwin gave the other a weak smile. "That man who…violated you…wasn't me…well, in a way he was. He looks like me, but I don't like to consider him as part of myself." Rivaille's eyes went a bit wide.

"Do you have a twin you never told me about?" Irwin shook his head.

"No…after the accident five years ago, Hanji was the first to notice it. She described it as seeing a side of me she never wanted to experience. When I came back to my senses, she conducted a lot of research on me."

Rivaille gasped slightly. "That was when you—"

Irwin nodded. "Yeah. And she diagnosed my…condition…as multiple personality disorder. That other side of me…he comes out whenever I go through extreme mental trauma." He paused to look at Rivaille with a remorseful gaze. "I'm guessing it happened when I found you feeding the bloodsu—"

"Vampire." Rivaille corrected, tapping his foot.

Irwin laughed nervously. "Ah, right. You're one too now." He seemed a bit nervous, and the shorter male tilted his head. "D-do I…need to step back more?" Rivaille shook his head.

"Nah. I can smell ya from a longer ways away, but trust me…your blood is no more appetizing than a pile of shit." There were about three seconds of silence before the blond broke out into laughter.

"Hah, really? That's a relief. I thought vampires just wanted anything they could get their hands on." Rivaille shrugged.

"That may be true for other rampant wild ones, but the ones I'm living with…they helped me get used to this…transformation." He chuckled, looking at the dirt. "There's only one person whose blood I'll drink anyway…I think I've become addicted to it." Irwin smiled knowingly.

"Is it the vampire boy?"

Rivaille's cheeks were the slightest shade of pink and he shook his head. "What? N-no, of course not." That only elicited another chuckle from the taller male.

Without saying anything more, Irwin mounted his horse again. Rivaille was about to voice why he was leaving so quickly, but was met with the other's hand raised a bit. "You and the other vampires are on a kill or capture warrant. Tomorrow at sunrise, the scouting legion is setting out for a search. If they find you, they might…" He trailed off, not wanting to finish his thought. Rivaille snorted.

"Ya must be losing faith in me if ya think those measly soldiers can lay a hand on me." He smirked a little, but worry never left the older man's face.

"If you can scare them off without killing them, I think the order can be withdrawn. I'm not the only one who's in your favor. Hanji and I, along with another young lady, all vouch for your side."

Rivaille waved his hand in the air and turned his back. "Of course. Don't worry; I'll make every single one of them shit in their pants." He turned his head once more. "I'm counting on you to watch my back." The blond nodded.

"I always do."
