After a week-long break, Fox's "Gotham" returns on Monday, May 2, with Season 2 episode 19, named "Azrael." The episode, which marks the return of one hated villain, is expected to take Bruce (David Mazouz) one step closer to becoming Batman.

Spoilers Ahead

In the previously aired "Pinewood," Bruce learnt that Dr Hugo Strange (BD Wong), alias the Philosopher, is the man who commissioned the death of the Waynes. This angered Bruce extremely, especially because he knows Strange used to be his father's friend.

Strange's experiments have now exceeded what Bruce's father would have anticipated. He now has the technology to bring people back from the dead, as proved by Patient 44, who is none other than Theo Galavan (James Frain).

In this second life, Theo calls himself Azrael and is even crazier than fans will remember. Comic book fans will know Azrael as a member of a long line of assassins created by The Sacred Order of Saint Dumas.

Azrael is still a captive of Dr Strange in the upcoming episode, and the fanatic doctor will release him to kill James Gordon (Ben McKenzie). From the promo for "Azreal," it is clear that Gordon is taking the fight to Strange and not waiting for him to make the first move.

However, Strange reminds the former GCPD detective: "The only reason you are sitting in that chair is because I allow it." The second half of "Gotham" Season 2 is definitely going to serve what it promised with the title "Wrath of the villains."

Meanwhile, Bruce demands justice for his parents' death from Gordon. Although the former cop tries reasoning with him, saying they don't have enough evidence against Strange, Bruce is adamant. It is understood that the young Master Wayne may take the next step towards becoming Batman in "Azrael." Bruce will find a way to avenge his parents, but it will happen later rather than sooner.

It is understood that Edward Nygma's (Cory Michael Smith) presence in Arkham will also have a huge impact on the future events in the season. "The people who have put Nygma [behind bars] wildly underestimated the person they think that they have locked up... When you put someone who's a master at puzzles inside a giant puzzle, he's going to find a way to get out of it," the show's executive producer John Stephens told TV Line.

Watch Season 2 episode 19 of "Gotham" at 8 p.m. (EST) on Monday, March 28. You can also live-stream "Azrael" via Fox Now.
