forced Dick Grayson to give up his Robin identity, Dick infiltrated Shrike's school, to earn back Batman's trust. Shrike was apparently the one to teach Dick the art of Escrima stick-fighting, as he was first seen using these weapons after training at the Vengeance Academy. When Shrike took out an assassination contract on Two-Face, he sent a number of his students to carry out the assassination, including Dick and Shrike's top student, a boy named Boone.
