A new clip from “Rogue One” was shown during last night’s Rogue One Special Event at Epcot that was hosted by The Disney Parks Blog. In this clip, we see Director Krennic asking Galen Erso to return to help complete the project that he had worked on. Galen is reluctant to return because he feels that The Empire has ulterior motives for his work. It also feels as though they may have once been friends.
