Moon Knight director Mohamed Diab explains the significance behind Layla El-Faouly becoming the Scarlet Scarab in the finale. Layla was first introduced in the MCU Disney+ series as the wife of Marc Spector, a mercenary who serves Khonshu as his avatar. As the show progressed, her story unfolded alongside Marc's as well as his Dissociative Identity Disorder (DID) alter Steven Grant's, revealing her to be much more than just a love interest.
The opening scene of Moon Knight episode 3 revealed more about Layla's life, most notably the mysterious fate of her archeologist father as well as her efforts to take stolen artifacts from thieves and return them to their rightful places. This is how she joined Marc in their shared adventures, one of which included finding the scarab that led to Ammit's tomb — something they never accomplished together, but Marc instead took up on his own. Her fighting skills were put on full display in that same episode, which revealed how Khonshu had been blackmailing Marc into maintaining his Moon Knight service by saying he would take Layla as his next avatar. With Steven warning Layla of this in episode 4, she knew not to accept that offer later on in the finale. Episode 6 did, however, see Layla become an avatar to someone else: Taweret herself. Layla transformed into none other than the Scarlet Scarab, a perfect fulfillment of how her father referred to her as his "little scarab."
