Moon Knight fans think they’ve worked out who killed Layla’s father

Moon Knight episode 4 features the revelation that Marc Spector had something to do with Layla's father's death. Spoilers ahead.

In episode 4, we learn that Layla's father, Abdullah El-Faouly, was an archaeologist as she emotionally reflects on how proud he would be to see her in Alexander the Great's tomb. However, during a chat with Arthur Harrow, the seed is planted that Marc may have been involved in his death at the hands of mercenaries. 

Confronting her husband about this, Layla asks Marc straight out if he killed her father. He denies his involvement explaining: "I was there. My partner got greedy and he executed everyone at the dig site. I tried to save your father, but I couldn’t save him." Marc also reveals he was shot too by his mysterious partner and should have died that night.

Harrow interrupted them with his men before we could find out who exactly his partner was – but could a fan theory have cracked it?

A new theory suggests that Marc's partner may have been another of his personalities, Jake Lockley. The character, who has not been introduced in the show yet, is a taxi driver known for his violent tendencies. 

Fans think his appearance has already been teased. In episode 3, it was hinted there was another personality after both Steven Grant and Marc had no memory of killing Harrow’s men. As well as this, in episode 4, it seemed like someone was trying to get out of the sarcophagus in Putnam Psychiatric Hospital.

If Lockley is about to be introduced in the show, some think it may have been him who is behind El-Faouly’s death. Speculating about this, one Reddit user wrote: "I think the Jake personality might have been the 'partner' Marc alluded to who executed Layla's father and his team. We already know
