This article contains spoilers for Moonlight Knight Episode 4, so read with caution!
The fourth episode of Moonlight Rider was already airing on Disney+ the day before yesterday, and there was a very big twist at the end of the episode, mark was eventually blocked by Arthur Harlow and the others who rushed in, Haro shot Mark in the chest, and then Mark woke up in a mental hospital.

In this psychiatric hospital, Mark becomes a patient and sees many of the characters who appear in the previous episodes. Arthur Harol became the attending physician, Lyra, the "sculpture" in the first two episodes, and his former colleague Donna became his patient friends, and in the second episode, the two policemen interrogating him and Mogart's subordinate Baker were both paramedics in the mental hospital, and he released another person, Ge Steven, from the sarcophagus as he escaped, and finally Mark and Steven saw Tavoret, the hippo goddess in ancient Egyptian mythology.
At the same time, some of the objects in the mental hospital also echo the previous episodes, such as Mark's feet tied to a wheelchair, the Rubik's Cube played by patients, the Moonlight Knight Toy, the goldfish, Arthur Harlow's crutches, and so on.
Even some foreign netizens found that in fact, the entire mental hospital also appeared in front.
Reddit user u/Flying_Moron discovers that in the second episode of Moonlight Knight, Steven Grant is kidnapped and taken to Arthur Harlow's cult base, which looks somewhat similar to this mental hospital.
In the second episode, Arthur Harlow's men hunt down Lyra and Steven, and as they escape, they go to a room full of corpses, where they are attacked by a monster that Haro summons from underground.
In the mental hospital at the end of episode four, Mark is taken to a room and sees the attending physician talking to him being Arthur Harrow.
This is Arthur Harlow's office in a mental hospital, and it looks a lot like the room with a lot of corpses in episode two.
Although curtains hung from the windows in the office, it could be seen that the windows were identical and in front of them were the same structure of columns and beams. In addition, the same arched niches can be seen on the right.
The scene of this mental hospital at the end of the fourth episode of "Moonlight Knight" has brought a lot of surprises to the audience, and I don't know how to follow up this unexpected ending next, hoping that there will be more surprises later.
