Memory about Lucas's sister

Nick was thinking are they just going to get together and do nothing? Or will they protect the inhabitants of the earth? Because what Nick currently believes, if someone fails to carry out a task, then the task will be given to someone who is better than the previous person, and that's the assumption that Nick is currently thinking about.

"Hh ..." Nick exhaled tiredly and looked up at the sky which now only revealed the lonely moon with no stars standing with him. Which made Nick now nod his head as he said,

"What happens if another star comes?" Nick muttered to himself, and seconds later he shook his head and said again, "Whatever it is... All I have to do now is gather them all, just as the boy intended." Nick muttered to himself which he then nodded his head in response to that before Nick finally went into the house and rested that night.
