Episode 5:
- Marc and Steven are dead, and find themselves awaiting judgement for the afterlife with the Egyptian goddess Tawaret. They go through memories in order to balance their hearts to make it to the Field of Reeds, the Egyptian afterlife. This is where we and Steven find out his origin: he's a DID created by Marc to deal with the actions, abuse and emotions of his mother, who completely abandons and blames Marc after Marc's brother dies in an accident.
- The scenes with Marc/Steven and Harrow-as-a-therapist are (IMO) part of Marc and Steven coming to terms with each other in their subconscience, but this part is a little fuzzier for me, and
@VectorVictor can fill in some blanks if I'm missing something.
- By the end of the episode, Marc and Steven's hearts are not in balance, and they cannot enter Paradise; therefore they are pulled into the sands of death by the dead; Steven saves Marc and "dies", balancing Marc's heart and earning him passage into Paradise.
Episode 6:
- Harrow retrieves the statue of Ammit and breaks it to revive her. She accepts Harrow as her Avatar and charges him with pre-judging the souls of the living. Harrow kills the avatars of the other Egyptian gods and leaves for Cairo.
- Tawaret convinces Layla to revive Khonshu to save Marc; Khonshu tries to persuede Layla to become his avatar, which she turns down.
- Marc saves Steven, and both are allowed to return to life by Osiris, the Egyptian god of the afterlife, as a response to Ammit's revival and Harrow killing the remaining avatars.
- Marc AND Steven both become Moon Knight again, and force Khonshu to agree to release them from their agreement after Ammit and Harrow's defeat.
- A dying avatar tells Layla to seal Ammit inside of Harrow in order to kill her. As it takes more than one avatar to seal Ammit, Layla agrees to become Tawaret's avatar (and gets a real cool suit in the process).
- MK and Layla fight Harrow in the streets while a Kaiju fight between Ammit and Khonshu takes place by the pyramids. Marc is on the verge of losing when he blacks out. When he comes to, he's holding Harrow's limp body, and everyone around him is dead/incapacitated.
- They seal Ammit in Harrow, Khonshu releases Marc and Steven, and we end on Marc and Steven waking up in Steven's apartment, able to switch back and forth at will between Identities, but still tied into their bed.
- The aftercredits scene reveals Jake Lockley, the third Identity (who is still bound to Khonshu). Jake takes Harrow/Ammit out of his psychiatric hospital and kills him with Khonshu in the back of a limo.
