Note: This episode contains spoilers for Episode 4 of Moon Knight, "The Tomb."
One of Moon Knight's central mysteries is its protagonist's different personalities. So far, the series has focused on two: Marc Spector and Steven Grant. Yet, in the comics, Spector has a third personality (out of four main ones): Cab driver and night-wanderer extraordinaire, Jake Lockley. There have been several clues pointing to his existence throughout the show's four episodes. The first one appears to have come in Episode 1, "The Goldfish Problem." In it, Steven Grant's puzzled to learn he's scheduled a date with a museum co-worker — given how Marc's in love with Layla, it made little sense for him to be the one to arrange the meet-up.
Then, in Episode 3, "The Friendly Type," Marc lost control of his body and awakened to find he had killed two people he was tracking. Horrified, he asked Steven what he had done, to which Grant replied it hadn't been him. After that, in Episode 4, "The Tomb," shortly after Spector woke up in the asylum, he found a sarcophagus with Steven trapped inside. They explored the place together until they came across another sarcophagus shaking violently, which was most likely housing Jake Lockley.
Moon Knight's mythology is quite complex. To help you prepare for Lockley's potential introduction, let's break down who he is, and the role he plays in the Fist of Khonshu's mythology.
Who Is Jake Lockley?
First, we need to understand where Lockley came from. At the beginning of the "Moon Knight" comics, Marc Spector did not have Dissociative Identity Disorder (DID). Instead, he created two other aliases for himself to aid in his Moon Knight crusade: Jake Lockley and Steven Grant. The latter was a successful businessperson who financed Spector's crimefighting, while Jake Lockley was the ear on the ground. Being a taxi driver operating in NYC's seedy underworld, Jake allowed Marc to be close to the criminal element without risking his (main) civilian identity.
It was later established that Marc had DID, and that his aliases were actually alternate personalities. As part of this new interpretation, Grant presented himself to Marc when he was a little boy, and Jake popped up during Spector's teenage years. Lockley was created at a time when Marc's family was concerned about his mental state, and so, his emergence prompted his parents to have him committed to a psychiatric institution.
The taxi driver has always been the gruffest personality in Marc Spector's arsenal. He isn't afraid to get his hands dirty and, as mentioned, knows his way around the criminal underworld. In the pages of "Moon Knight" #15, from 1982, co-creator Doug Moench wrote a section explaining Marc Spector's world titled "The Shades of Moon Knight," in which he described Lockley as follows (via CBR.com):
"I see Lockley as the man Moon Knight is most comfortable with — no pretensions and no real responsibilities, always on the move, always in contact with people on an easy, earth level. Indeed, Lockley is the closest to Spector, MK's "real" identity, yet he lacks Spector's guilt and grimness while possessing a capacity for humor and absurdity."

It may seem counterintuitive to describe a hardened crimefighter so involved in the dark side of society as being guilt-free and laid back, but it was true to a degree. Lockley was relatively sociable, being able to find people to be his street informants. In fact, he befriended a diner owner named Gina and her children, as well as a homeless man named Bertrand Crawley.
Still, Lockley's relaxed portrayal has not prevented him from being arguably Marc's roughest personality. That's especially true in some modern interpretations of the character that have depicted him as Spector's "unhinged" side (a good example being 2016's "Moon Knight" #9). He can be quite violent, a trait that appears to be part of the MCU's Moon Knight (more on that below).
Family History
Believe it or not, Lockley has a family of his own... well, sort of. At one point in Moon Knight's comic-book history, he and his longtime love interest, Marlene Alraune, decided to break up due to Marc's crimefighting lifestyle. Some time passed, and the hero returned to Marlene, this time using the Jake Lockley persona. They reconnected and had a daughter named Diatrice Alraune.
Here's the catch, though: Marlene and Jake agreed to keep the baby a secret from Steven Grant and Marc. The two identities eventually learned of the girl's existence, and were understandably shocked about it. Diatrice made her first appearance in 2017's "Moon Knight" #190, and has remained an important aspect of Moon Knight's mythology since (despite not appearing in many stories).
Will Lockley Be Changed for the MCU?
Moon Knight has taken some significant creative liberties with Steven Grant. Originally a super-successful movie producer whose fortune allowed Spector to finance his Moon Knight escapades, the MCU's Grant is a British gift-shop employee well-versed in Egyptian mythology. In that vein, Jake Lockley (again, assuming Lockley is indeed the personality being teased) seems to have gone through some minor alterations for the MCU.
For starters, he appears to be extremely blood-thirsty, even more so than his comic-book counterpart. While — as mentioned above — Lockley has been portrayed to relish violence, Moon Knight's third personality appears to be on another level. Furthermore, (and this is some heavy speculation), there is a slight possibility of Lockley being British.
When Steven's museum co-worker reminded him about their date in Episode 1, she didn't mention any accent differences between the alternate personality that seemingly asked her out and Grant, which could indicate that the identity, like Grant, has a British accent.
Of course, we ultimately have to wait and see, firstly, if Marvel Studios is indeed bringing Jake Lockley to live-action, and secondly (assuming he is indeed coming), how he will be adapted.
