Synopsis for "The Lesson: Grass Before the Scythe, Part One"
Stephanie Brown draws a comic explaining the history of the Batman Family for Wendy Harris before attending a study group with Francisco Gracia and Jordanna Spence. She discovers she brought the backpack with Batgirl costume rather than the bonus packet, and Jordanna reams her out. Stephanie sees Newton Flitwik running past and changes into her costume to follow him.
Newton is surrounded by a group of people in cloaks, two of whom Batgirl identifies as an English major and a History major from their references. Batgirl tells him to run while she fights his attackers, and she is assisted by the “Grey Ghost,” whom Oracle quickly identifies as Clancy Johnson, released on “reasons of mental instability.” Batgirl tells him she doesn’t need a sidekick, to which he responds, “You will.” He disappears in a flash of light. The “reapers” take advantage and also vanish. They track Newton down again to demand “what we asked for,” which is held on his flash drive, but Newton refuses.
Detective Gage is called to Gotham University the next morning to investigate the apparent suicide of Newton Flitwik. He suspects foul play because something was stolen from him, and Barbara Gordon tells him people in robes were seen chasing Newton. This disturbs Gage, and he walks away. Another officer brings Gage a piece of evidence that Gage insists wasn’t there a second ago—a bloody batarang.
Crystal Brown is worried about her daughter since the newspapers have reported Newton’s “suicide” was the result of college stress, and she wonders whether they should move away from Gotham. Steph reassures her. Later, Batgirl and Oracle have failed to find any information on the “reapers,” and when she sees the Bat-Signal go up, Batgirl decides to look into it. Oracle and Proxy see a news report but are too late to warn Batgirl, and when she lands on the roof of the GCPD Headquarters, she is surrounded by police officers and is told she is under arrest for the murder of Newton Flitwik.
