SEASON FINALE: Tonight is the Season 4 finale for this prequel series, setting the stage for the Batman universe in Gotham City. So even though there’s one more episode, and season, to go, things have gotten closer to revealing the true nature of both the villains and the heroes in this show. And tonight, two of them come face to face (but not with Two-Face; he’s not one of the villains expected in this episode), as Jim Gordon, played by Ben McKenzie, confronts Jeremiah, played by Cameron Monaghan. Jeremiah, in recent weeks, has inherited his late twin brother Jerome’s mantle as the future Joker. No, I’m not Joking. That job’s taken – twice.
