Next week, Mark Hamill makes his return to the DCU, reprising his role as the Trickster from the 1990 "Flash" series on next week's episode of "The Flash." Hamill plays James Jesse, an incarcerated costumed criminal who finds himself suddenly relevant once again when a new version of the Trickster (Devon Graye) terrorizes Central City. Barry Allen turns to Jesse for help, a move that backfires and places himself, and everyone around him, in grave danger.
