A quick verification identified her as she broadcast her credentials, as well as the rest of the Mandalorians present. They had thrown their lot in with the Imperials, an unexpected move given recent galactic events. He was cutting it close, but the time for smoke and mirrors was quickly drawing to a close. However, he still had one last card to play, a gambit for time. He might lose this battle, but he would win the war, and not one of them would knew what hit them in the coming storm.
Using the open comms ports on her helmet, Kain fed the girl who had fashioned herself Mand'alor data that would cause her to pause.
