and the two traveled back into the past nine weeks to see what has really happened to Joseph only to find out that Samuel himself killed his own brother for selling him out to the governement. Upon their return Samuel got suspicious and to escape the unnecessary questioning, accused Edgar for killing Joseph,but thanks to Hiro, Edgar was safe and he told Lydia that they will defead Samuel together.
