What Costa Left Behind at the Club

The bite mark on graduate student Renata Osei’s neck had healed within two days, considerably faster than any wound she’d previously experienced, and it was the third night after the incident at Club Meridian, when she found herself craving nothing but raw meat and recoiling violently from sunlight through her apartment window, that she finally accepted something had gone genuinely, irreversibly wrong.

“You need to tell me exactly what happened that night,” her roommate, Priya Marsh, said, watching Renata with growing alarm as she pulled the blackout curtains tighter for the third time that morning. “You’ve barely eaten anything except that steak I found you eating raw in the kitchen at four in the morning. That’s not normal, Renata, and I’m genuinely scared for you.”

“I met someone. At the club. He was—” Renata struggled to articulate what had happened, the memory carrying a strange, dreamlike quality that resisted clear recollection. “He said his name was Costa. We talked for a while, and then he asked to see me outside, and I remember him being very close to my neck, and then I don’t remember anything else clearly until I woke up the next morning.”

“That sounds like an assault, Renata. We need to go to the hospital, file a police report—”

“I don’t think a hospital can help with what’s actually happening to me, Priya.” Renata pulled back the collar of her shirt, revealing the wound that should have still been raw and inflamed but instead showed only the faintest trace of two small punctures, healed with an unnatural speed. “Something is wrong with me. I can feel it. My senses are different. I heard your heartbeat from across the apartment this morning, clear as if you were standing right next to me.”

The days that followed brought changes considerably more alarming than heightened senses — Renata’s reflection began appearing faintly translucent in mirrors, her body temperature dropped to levels that would have been medically concerning if she still trusted doctors to understand what was actually happening to her, and the craving for raw meat evolved, with mounting horror, into something considerably darker that she fought against with every ounce of willpower she possessed.

“I think I need blood,” she finally admitted to Priya, her voice breaking with shame and terror in equal measure. “Not metaphorically. I mean it literally, Priya. I can feel it, some kind of hunger building that steak isn’t satisfying anymore, and I am terrified of what happens when I can’t control it any longer.”

They found Costa through painstaking research into the club’s regular patrons, eventually locating him at a considerably more exclusive gathering that Priya, posing as an interested newcomer, managed to infiltrate on Renata’s behalf.

“You did this to me,” Renata said, confronting him directly once Priya had arranged the meeting, her voice carrying a fury that surprised even herself. “Whatever you are, whatever happened that night, you need to tell me how to either fix this or manage it, because I cannot live like this.”

Costa’s expression carried genuine, unexpected regret. “I wasn’t supposed to feed that night. I’d been trying, for years, to control it, to only take what I genuinely needed without turning anyone. I made a mistake with you, one I’ve been trying to figure out how to address ever since, without simply making things worse.”

“Address it how? Can this be reversed?”

“No,” he said simply, and Renata felt the word land with the weight of a door closing permanently on the life she’d previously known. “But it can be managed, if you’re willing to learn, and if you’re willing to accept help from someone who’s spent considerably longer than you’d believe learning exactly how to live with what we are without becoming a monster in the process.”

The months that followed brought Renata into an entirely different existence than she’d ever imagined possible, learning under Costa’s reluctant, guilt-driven mentorship how to manage the hunger without succumbing to it entirely, how to source what she needed without harming anyone unwilling, and how to navigate a daylight world that no longer fully welcomed her presence.

“Do you regret it?” she asked him once, months into her difficult transition, watching the careful, disciplined restraint he’d built over what she now understood was considerably more than a few decades of practice. “Turning me, I mean. Do you wish it had never happened?”

“Every single day,” Costa admitted, his ancient eyes carrying a weariness that made Renata’s own recent struggle feel, briefly, almost bearable by comparison. “But regret doesn’t undo what’s already done, Renata. It only shapes what we choose to do with the time we have left, however considerably longer that time now stretches for both of us.”

Priya remained her closest, most steadfast connection to her old life, a friendship that strained under the weight of Renata’s new existence but never fully broke, and Renata, adjusting slowly to a permanence she’d never asked for, found herself grateful, despite everything, that she hadn’t been forced to navigate this transformation entirely alone.

“We’ll figure this out together,” Priya told her, on the nights when the hunger felt overwhelming and Renata’s fear of what she might become threatened to consume her entirely. “Whatever this is now, you’re still you underneath it. I refuse to believe otherwise.”

Renata held onto that reassurance the way she now held onto very little else from her previous life, understanding, with each passing month, that survival in this strange new existence would require every ounce of the humanity Priya still saw in her, carefully guarded against a hunger that never, entirely, went quiet.

Costa’s own decades of careful discipline became, gradually, something closer to genuine mentorship than obligation, and he found himself, watching Renata’s slow, determined progress, remembering for the first time in years what it had actually felt like to be newly, frighteningly changed, rather than simply, wearily accustomed to what he’d become.

Priya eventually reduced her own hours at work considerably, restructuring her entire schedule around Renata’s new nocturnal rhythms, and though she never spoke of the sacrifice as anything remarkable, Renata understood, with each passing month, exactly how much genuine loyalty her friend’s quiet, consistent presence actually represented.
