A/N: Sorry I'm posting so late. I know I promised but I've been EXTREMEMLY busy. Thank you for even more positive feedback. I will post two chapters - this one today and another one tomorrow - to make up for it :)

Chapter 3

Hearing Nico yell his sister's name, The Doctor's eyes widened. He sprinted to Nico and pulled him to one side.

"What the hell are you doing?!" The Doctor questioned, still keeping a tight grip on Nico's arm.

"Finding my sister. Now get your filthy hands off me!" Reluctantly, his grip got weaker.

"Nico, before you go and find your sister, I need to ask you something. Are you willing to risk your future, and the futures of all you have met, to see your sister one more time?" Nico froze.

"What are you talking about?" he murmured. He could feel his heart rate soaring.

"It's...wibbly-wobbly-timey-wimey stuff. You wouldn't understand." Nico crossed his bony arms together.

"Try me."

The Doctor sighed impatiently. They didn't have time for this.

"Okay...as soon as you talk to your sister, your world will change. Some people will forget who you are. Some people may cease existence entirely. Yes, you will have your sister again...but you would not have anyone else." Nico's mind was racing. He thought about Hazel and Frank, Annabeth and Percy. All of the friends he had made, and some of them, if not all of them, could die in an instance...but he remembered that they had each other. No one really loved Nico like Bianca did. Nico looked up into the Doctor's eyes.

"I'll risk it," he muttered. Shrugging and admitting defeat, The Doctor watched as Nico ran towards his sister. Waiting a few seconds, he followed on.

"...and we get a step-sister called Hazel," Doctor heard Nico say. Bianca looked confused and slightly scared, and the younger Nico was nowhere to be seen. After a while of awkward silence, Bianca shrugged, a smile creeping back onto her face.

"Whatever. I guess I'll believe you," she mumbled, sounding almost drunk. The Doctor frowned, sensing something was wrong. He walked up to Bianca and held his sonic screwdriver in his right hand.

"Hello, Bianca. If you don't mind, could you look into this little light at the end of this screwdriver please?" His speech was rushed. Holding the sonic screwdriver up to Bianca's face, he clicked a button and Bianca suddenly looked dazed.

"Woah!" she yelped soberly. "Who are yo-"

"Long story short, I'm the Doctor. He's your brother grown up." Pointing to Nico, The Doctor grinned awkwardly.

"So...wait, you're Nico?" Bianca whispered, staring into Nico's eyes. Nico, meanwhile, was desperately fighting back tears. He felt words building up, ready to fly out of his mouth. After a few seconds, the words were freed.

"Do you want to come with us?" he blurted out unexpectedly. Bianca jumped back in shock. After letting the words sink in, she nodded. Nico averted his attention to the Doctor, who looked back at him and nodded extremely reluctantly. The two children ran into the TARDIS, squealing with delight. Nico had never felt happier in all his life.

The Doctor chuckled to himself. "Kids," he said to himself. He twirled his sonic screwdriver in his hand before stepping into his TARDIS.
