"No," Ethan replied, his mind still trying to process the reality of the beings before him. "I don't know your father."
His gaze drifted back to the wristband on his arm, the faint blue light still pulsing steadily. As he looked at it, the taller alien, Ziak, suddenly produced a sleek, silver weapon, pointing it directly at Ethan.
"Woah, woah, chill!" Ethan exclaimed, instinctively raising his hands in a gesture of peace.
The shorter twin, Kiaz, his luminous eyes fixed on the wristband, spoke quickly. "Where did you get that? That device… it's our father's tracker."
"This?" Ethan gestured to the band on his wrist. "It was like… a metal piece. I found it in my mother's closet and was just playing with it. It sort of… unfolded and turned into this."
Kiaz's gaze intensified. "Your mother? We need to meet her. Now."
Ethan hesitated. "Wait a minute. Who are you? Why do you need to meet my mother? And… how are you speaking my language?"
Ziak slowly lowered his weapon, a look of something akin to embarrassment on his violet face. "Apologies, earthling. Our urgency… it was impolite." He inclined his head slightly. "We are from the planet Nebula-4, which you might designate as KP6-0087, approximately 450 light-years from your… Earth. I am Ziak, and this is my twin, Kiaz."
Ethan's eyes widened further. "So… aliens are real." It wasn't a question. Then, his curiosity surged again. "Why did you come to Earth? And why do you need to meet my mother?"
Kiaz stepped forward, his gaze still sharp. "Our father… he was on a vital mission. He went missing four of your years ago. Recently, we received a faint signal from his tracking device." He gestured towards Ethan's wrist. "That device. The signal originated from this location. We believed it was him. However," he paused, his gaze piercing, "the… extraordinary level of neutrino content within your biological structure… it mirrors his. We need to understand why his tracker is with your mother and why you possess such a unique bio-signature. Meeting her is crucial to finding him."
