No. 3 couldn't help but chuckle as her blonde sister debated what they ought to call themselves. A team name was probably the least of their worries right now, and whether she said "sis" or "sister" seemed irrelevant. Words were merely a convenience, and as long as people agreed to call things by the same name, nothing else really mattered. It almost seemed childish to ruminate over such things, but at the same time it was endearing. If anything, the quirk made her more fond of her sister, as if she managed to cling to something precious. "I'll leave the creativity up to you," she said, patting No. 1 on the back. "My only suggestion is that if we name ourselves, it ought to be something that strikes fear into the Varden." 

With that she turned to No. 2 and gave her a nod. "Yes, let's go. We have nothing to gain by waiting." However, as they approached the tower, she felt the nanobots buzzing inside of her. They were replicating, preparing for some pre-programmed procedure. "I... I think I should scout ahead," she said, after a moment's hesitation. "You two stick together. I'll let you know if I see any danger, then we can attack as a unit if I find anything." 

She took a breath and decided to allow the nanobots to carry out their task. She wasn't sure what they were doing, but it felt right to just let them do it. No. 3 didn't notice what happened, but her sisters would see an electric flicker, and then nothing. No.3 became completely invisible; only a distortion of space and the raindrops running along her body gave any indication of where she stood. She darted towards the tower, her feet falling silently against the ground. She didn't have to think to do so. Her muscles knew where to place her feet to make as little noise as possible. She crouched low, seeking cover in shadows as she approached the tower with a rapidity that surprised her. She kept an eye out for any Varden and tried to assess what security and obstacles were blocking their way to the tower. Once she had this information, she would return to her sisters.
