Keiko turned around as Silas moved over to her and told her that she wasn't going to tell him to go back. She didn't want to say 'this has nothing to do with you' since, with the death of one of their friends, it did have something to do with them. "Fine, have it your way". She suddenly moved backwards, two Talismans appearing in her hands. She then threw them onto the walls beside her so that they were across from each other. With a wave of her hand, a line of energy connected the two talismans before a glowing wall would now be between her, Silas, and Sasha. 

"I cannot let you come along though, but... if you can break this barrier then I will accept your help. If not... please turn back, there is nothing wrong with leaving to live another day". She had an apologetic tone to her voice, as she didn't want to do this, but saw no other choice. After that she began to go up the stairs to the next floor, leaving Sasha and Silas the choice of either turning back or trying to break the barrier Keiko had created so that they could advance.
