They decided to deactivate themselv

They decided to deactivate themselves? Put themselves in a sleep?" Misaka was shocked at the clone's unanimous decision, "How could they?"
"Perhaps they felt that without our saviour as a goal for them, their need for existence was… diminished, Misaka says sadly," Misaka 10032 said softly as Misaka Mikoto offered her a cup of warm water. "Onee-sama is suffering too, isn't she? Misaka asks worriedly"
Misaka smiled wanly, "I had him, you know. He was right in front of me, that idiot. And he still kept it with him, all this while." She looked down at the ragged gekota charm with a tortured expression and sniffed, shaking her head wildly, "see what he's done to me? I'm not one for crying but he… he…" Misaka Mikoto finally looked at 10032, "And what about you?"
Misaka 10032 looked down, "I do not know, Misaka explains. Misaka feels as if something important was just taken away from her. Misaka does not know the concept of 'love' but Misaka feels happy when she is with our saviour. And now that he is gone, Misaka feels… empty." Misaka 10032 could feel something moist on her cheeks.
Misaka Mikoto leaned over and wiped off the tears gently, her smile warm, yet saddening at the same time. "You're crying."
"I do not comprehend…" Misaka 10032 whispered as the tears fell, "Is this... what it means to lose a loved one?"
Misaka nodded as she held her younger sister in a tight embrace, "Yes. Yes, it is," she said softly as Misaka 10032 finally hugged her back. "I'm sorry. I know you must be suffering too, so why," Misaka held her breath, "why did you not do the same?"
10032 met Misaka's eyes earnestly, "Because Misaka is sure that our saviour would not want us to give up life so easily. He saved us, the Sisters. He would be upset if we simply gave up without him, Misaka feels this way."
The Railgun's eyes widened at this simple explanation that made so much sense. Yes, Touma would not be happy if she moped about his death. Hadn't he said that he helped people because their happiness was what made him risk his life to see their smiles, their world safe and sound?
And she finally understood something else. She had her friends, her family that would support her, give her the care she needs and help her back up. All her sisters had were themselves… and now, this lone sister of hers did not have anyone else but her.
Misaka Mikoto's lips trembled as she smiled tremulously, "Of course. He would never have wanted us to do that," she replied, patting her sister on the head as renewed vigour surged through her. She was the Railgun, the Ace of Tokiwadai. But most importantly, she now had a goal. "He would have wanted us to keep fighting for ourselves… and for others."
She would reach the same level he had. To protect the people around her, she needed to delve into the darkness that he faced. To understand the forces that had taken him away. But before that…
"I'm going to take you to meet someone. She's arriving today," Misaka Mikoto said as she stood up.
"Meet someone?" Misaka 10032 looked at her sister curiously.
Misaka Mikoto, her older sister, smiled. "I'm taking you to meet our Okaa-san.
