“Gotham” fans will learn more about Alfred Pennyworth’s (Sean Pertwee) mysterious past in Season 4. Fox

Alfred Pennyworth (Sean Pertwee) from “Gotham” is unlike other variations of his character in the comic books and movies. In the series, he’s a tough guy who taught young Bruce Wayne (David Mazouz) everything he knows about moral fortitude and combat, which would later be essential as Bruce embraces his vigilante persona as the Batman.

But little is known about Alfred’s character, save for his past stint with the British Special Air Services. This coming Season 4, however, fans will get to know more about the mysterious butler and his past.

“I think you’re going to find out indirectly about his past, and the person that he was. He’s not proud. He has more demons than Bruce has. And that’s why they’ve always inevitably sort of drawn together, and they find each other, and that relationship suffers as the young boy grows,” Pertwee told Cinema Blend. “Alfred tries to keep up with him, and he just can’t.”

Next season, one of the most exciting things the characters will have to deal with is the return of the Scarecrow, also known as Jonathan Crane (Charlie Tahan). His origin story was established during the 15th episode of Season 1, after Detective Jim Gordon (Ben McKenzie) and his partner Harvey Bullock (Donal Logue) went after his father, Gerald, for harvesting the adrenal glands of his murder victims.

Jonathan was last seen screaming in terror in the hospital, after being injected by his father’s experiment and being subjected to a constant state of terror. This time, it will be the Scarecrow who will bring the terror to Gothamites.

“Scarecrow comes back in season 4,” Mazouz told Comic Book. “It’s on full blast, I’m really excited.”

The first teaser about the Scarecrow’s reappearance was actually made by McKenzie several months ago. “There are some villains that I’m a fan of that are in season four,” McKenzie told Comic Book Resources. “I’ve always been keen on the Scarecrow. It would be nice if the Scarecrow showed up.”

“Gotham” Season 4 will be released by Fox on Sept. 21, a week earlier than scheduled.
