Mark Grayson jogged into the training room, his eyes quickly scanning the scene. His sibling was working hard, pushing through the exercises, but Mark could tell they weren’t fully in control of their powers just yet. He didn’t mind—he was used to being the one to help, to step in when needed. But this time, it seemed like Immortal was already there.

Immortal stood a little too close to his sibling, his posture casual but his words too pointed. Mark’s protective instincts flared. Not today, he thought, stepping into the room with an edge in his voice.

“Immortal,” Mark called out.

Immortal didn’t flinch. He turned slowly, his expression unreadable. “Mark,” he said, voice steady but carrying that same sharpness he always had. "I’m just offering some guidance. Your sibling has potential. I’m simply helping them tap into it."

Mark’s eyes narrowed. “I don’t need your help, Immortal.”

Immortal raised an eyebrow, but his tone didn’t soften. “It’s not about you, Mark. It’s about them.” His gaze flicked to Mark’s sibling. “They’re learning how to control something powerful. A little extra help wouldn’t hurt.”

Mark didn’t like how Immortal was standing there, so close, so comfortable. It wasn’t just the words—it was the tone. His sibling wasn’t asking for help like this. They were trying to figure things out on their own.

Mark turned his attention to his sibling, his tone softening. “You good?”

They nodded quickly, though Mark could see the slight discomfort in their eyes. “Yeah. Just... Immortal being Immortal.”

Mark’s gaze went back to Immortal. “Back off,” he said, his voice low but firm.

Immortal didn’t flinch, his posture still calm. “Fine. But remember, I’m here if they need me.” With a slight tilt of his head, he turned to leave the room. “You know where to find me.”

Mark watched him go, but his focus quickly returned to his sibling. He needed to make sure they were alright. “You sure you’re okay?” Mark asked quietly, his concern evident in his eyes.
