Something to keep in mind: I believe it was implied that Batgirl and Robin didn't start their end of researching the Scarab until after Doctor Fate completed his translation of the hyroglyphics. Plus, just because Black Canary didn't share with Jaime the League's conclusion that the Scarab was designed by the Reach, doesn't mean Batgirl and Robin hadn't already considered that possibility once Fate completed his work.
