Diego: You stayed because you couldn't let go of the way things used to be. The Academy. Dad. With Allison. Dad's dead. Mom too, now. We're orphans again, dude.
"Man on the Moon" is the fourth episode of The Umbrella Academy's first season.
Seven years ago, Luther, then the only child left in the mansion, was severely wounded in a mission. Apparently to save his life, Reginald injected him with a serum that gave him his current body. Hazel and Cha-Cha have difficulty getting information out of Klaus. Diego confides in Eudora about the attack. Having heard from Klaus that Five is searching for the eyeballs' owner, Cha-Cha and Hazel blow up the lab.
Allison accosts Leonard in Vanya's apartment, and later gets a drink with her. Luther and Diego clash at first before going on to find Five, eventually stumbling upon him in the library. Klaus makes contact with Hazel and Cha-Cha's previous victims. Eudora busts into the motel room and frees Klaus, but is killed in the attempt. Klaus escapes through the vents with Hazel's briefcase, the contents of which teleport him elsewhere. Diego finds Eudora's body.
- Adult Fear: Diego and Luther realize they forgot about their other brother and realize he was kidnapped by dangerous people.
- Air Vent Escape: How Klaus manages to leave the motel room.
- All Men Are Perverts: Allison alerts Vanya to the possibility that Leonard let himself into her flat so he could jerk off on her teddy bear. Followed by her saying that man are unredeemable shits sometimes.
- The Dead Have Names: Klaus taunts Hazel and Cha-Cha with the names and deaths of their previous victims.
- Face Your Fears: Via flashback we learn that Reginald Hargreeves locked little Klaus in a crypt hoping that the exposure to the ghosts of the dead will cure him from his fear of them. It's apparent that this method didn't work out.
- Funny Background Event: After Klaus talks to Hazel and Cha-Cha about their past victims, Ben commends him on handling it. After it cuts back to Klaus, Ben and another of the assassins' victims high-five.
- Headphones Equal Isolation: The cleaning lady at the motel doesn't hear Klaus in the closet because she has her earphones on.
- Hitman with a Heart: Hazel is revealed to be this, having spared more victims than Cha-Cha would like.
- Intoxication Ensues: Hazel and Cha-Cha ingest some of Klaus's weed chocolate, and are high as kites when they infiltrate the prosthetic lab.
- No Good Deed Goes Unpunished: Patch goes to rescue Klaus when she hears muffled sounds from a motel room. She ends up saving his life, but gets killed in turn because she forgot there were two intruders.
- Noodle Incident: Comes up in conversation between Hazel and Cha-Cha.Hazel: Remember Trinidad?
Cha-Cha: How could I forget Trinidad.
- Oh, Crap!: Diego's wrestling buddy delivers Patch's message that she found his brother at a motel. Diego and Luther look at the drunken Five, and both say, "Klaus" at the same time.
- Ominously Open Door: Allison is alerted when she finds the door to Vanya's apartment ajar. Inside she bumps into Leonard.
- Poor Communication Kills: A downplayed but no less deadly example at the start of the episode, Diego tells Patch his brother has been missing for two days. He's talking about Number Five, but Patch tracks down Klaus and gets shot by Hazel and Cha-Cha for her efforts.
- Rapid-Fire "No!": Diego's reaction when finding Patch.
- Sentimental Music Cue: When Diego finds Patch at the hotel, the emotional ballad "This Year's Love" by David Gray is playing on the soundtrack.
- Something We Forgot: Diego and Luther realize they never accounted for Klaus after Hazel and Cha-Cha attacked them.
- Split Screen: Used for the Intoxication Ensues sequence.
- Too Kinky to Torture: Hazel and Cha-Cha tortured Klaus for 10 hours trying to get information about Five. By the time we see them, he's getting aroused from strangulation and treating waterboarding as a refreshing drink.
- Torture Is Ineffective: In addition to the Too Kinky to Torture example, Klaus mocks Hazel and Cha-Cha for 1: kidnapping the one Hargreeve who doesn't know anything, and 2: who is so useless that no one will even notice he's gone, making him worthless as a hostage. Indeed, it's not until the very end of the episode (after Klaus has already escaped) that Allison realizes he's missing.
- Vomit Discretion Shot: Number Five gets drunk but the young body doesn't take it well. His vomiting is hidden from the camera though.
- Wham Shot: While his interaction with Allison in Vanya's apartment already raises a red flag, the confirmation that Leonard is not all that he seems is when he flushes Vanya's medication down the sink.
