Unlike everyone else who wore bracelets, Santana didn't. The only thing she had on, well in her, was an implant just behind her ear that allowed her to communicate with her family members. It was outfitted with the best A.I. technology that Number 13 could create right now. So, it was extremely user friendly, and it also came with two contacts that would allow them to share their vision, scan faces of those that they see, see marked locations on a 3D map that any of their family members can make. Along with a number of other similar features.
Number 1 had hers turned off, but she still had them in because they were clear and did not affect her vision or inconvenience her in any way. So, it was better for her to just leave them in.
She put it on silent when she left the base after taking the blows from Number 2, but once she turned it back on as she made her way back to the base several messages were played.
