In 'Revenge of the Rogues,' episode 1x10 of The Flash, Dr Caitlin Snow talks with graduate student Jason Rusch in the Jitters coffee house. Jason says, “Professor Stein wanted to skip ahead to stage three. We melted a concrete wall. Then the Army showed up confiscated all of our research.”
Remember in episode 1x05 (Plastique) when Clancy Brown's Major General Wade Eiling and his covert ops unit muscled in on the Central City Police? Eiling confiscated evidence and took over the case.
My personal theory is that it was Eiling's covert ops unit that confiscated Stein and his team's research on FIRESTORM.
