"Mycroft, I need a favour," John admitted as soon as Mycroft picked up his phone.

"Don't worry, I have her here," he replied calmly to John's relief.

"She's with Mycroft," He enunciated to his friend before taking the phone up to his ear again.

"Don't worry, we'll come pick her up. Where are you?" John asked.

"Actually, it has come to my attention that this might not be the best solution," Mycroft informed John.

"What do you mean?" he asked and looked at Sherlock who was desperately trying to hear what was being said.

"Well, I was aware Sherlock never had any intentions of raising the child, I thought him seeing how alike they are might get him on better thoughts. But, seeming as it hasn't..." His voice went silent.

"No, Mycroft, you don't understand," John argued and shot Sherlock an angry look while passing him to get to the kitchen.

"What don't I understand, John? Did you not think I would be keeping an eye on my niece? My brother clearly stated that he wanted her to leave and not return, so he get his wish, and Penrose gets a place to stay," Mycroft explained, as if he'd solved all the issues by that. John quickly covered the microphone on his phone before turning to Sherlock.

"You told Macy to leave?" he whispered loudly before turning back around.

"Listen, Mycroft, I get it, you just want the best for her. So do I-"

"So do you?" Mycroft interrupted through the phone; "John, this girl is nothing to you. She is Sherlock's daughter, and I thought that would force him to at least keep her safe. But since he won't, I will."

John sighed.

"Mycroft, she might very well not be my daughter, but I have grown fond for her-"

"What, over the last four days?" Mycroft interrupted with a snicker.

"Mycroft! I care about the girl! Let her come back and stay with her father like she's supposed to!" He argued angrily before feeling someone picking the phone right out of his hand. He turned to Sherlock who calmly put it against his own ear.

"Hello, brother," he greeted. John took a step closer to better hear what Mycroft replied.

"She is not your daughter, but she is mine. I will take care of her," Sherlock promised.

"Is she your daughter? You have not treated her like it," John heard Mycroft through the phone before Sherlock stepped further away from him.

"Mycroft, do not do this. You do not have time for a child," he argued tiredly to the box he held against his ear.

"We're coming to pick her up," he decided after listening to his brother for a while.

"You can't deny for me to see her at the least. We're on our way. No, he's coming.

He's the closest to a father she's got, he's coming." With that Sherlock ended the call and turned to his friend.

"Well, are you ready?" he asked proudly and handed a smiling John his coat.
