Keep My Promise.
~ Frisk

My Promise is the 5th episode of Glitchtale's 2nd Season.


The episode starts with Betty at an unknown location having a fit of rage about the fact that she is the one to run when others are supposed to be afraid of her terrifying, Akumu.


Seeing this, she cools down and apologizes, saying how she feels different with the HATE inside of her, further elaborating that it has its own goals. Akumu then turns into a sort of force field per Betty's command and shows the SOULs they have collected. Seeing most of the Souls are partially corrupted by HATE, Betty breaks several of them and demands that all the rest, excluding Asriel's, be discarded and destroyed. In the process, she drains the soul of Cam, breaking it almost immediately after. She then tells Akumu to use some HATE on Asriel.

After this, Betty says that she doesn't care if humans see her the same way anymore, and she "never got used to being split in two anyway". She aims her spear at Akumu, saying it was fun while it lasted, and tosses the spear at Akumu, which impales him, and then impales herself in the chest, thus becoming one with Akumu. She then turns into her true form and gains a new and more horrifying appearance. She then asks the newly formed Asriel if he is ready to hunt down the people who hurt him so much.

Meanwhile, Jessica confides to Undyne that she feels she has made nothing but mistakes in her life. In response, Undyne makes a confession of her own to Jessica that she feels she is responsible for Alphys' demise, and not Betty. Jessica consoles Undyne that she must accept her grief and pain and that it took her 20 years to learn that.

But this calming moment quickly comes to an end upon them hearing rather disturbing noises, causing Jessica to investigate and discover that Pink Creatures managed to break the reinforced Kindness windows and get into the house.

She defeats one with the Nullifier Gun, but her SOUL cracks in response. Meanwhile, Undyne fights some others off with her spear. Jessica is grabbed by another Pink Creature, and she screams to Undyne for help. However, Undyne cannot toss her spear towards the Pink Creature because she suffers a hallucination of Alphys in Jessica's place, about to be murdered by the Pink Creature. Without Undyne's intervention, the pink creature stabs Jessica in the stomach. This finally snaps Undyne out of her hallucination and encourages her to throw the spear at the pink creature, but is interrupted by Asgore's trident being thrown at the Pink Creature, ultimately killing it. Jessica passes out from pain and blood loss.

Asgore and the others had just arrived on the scene, with Sans still in his comatose state. Toriel starts healing Jessica, who regains consciousness temporarily before slipping back into unconsciousness. Gaster heads down to his lab in the Underground with Sans and Papyrus. While Frisk begins to enter but flinches, looking at his glitching hand.

In the lab, Gaster tries to remember his password. Suddenly, the lab triggers him into remembering flashbacks of his time in the Void. Papyrus worries about Gaster and his PTSD, but they press on into the laboratory. Gaster has Papyrus lay Sans down in a special ICU- like bed and then asks Papyrus to get him some supplies. While Papyrus is busy, Gaster views Sans's condition on the screen. It says Sans is fallen down (the audience is later informed that "Fallen Down" means Sans' condition is essentially terminal and he will turn into dust soon), and Gaster is horrified at the results, staring at the screen in disbelief. When Papyrus gets back, Dr. Gaster hastily shuts off the computer so Papyrus will not see his brother's diagnosis. When Papyrus asks about Sans' condition, Dr. Gaster lies to Papyrus that Sans' condition is stable and he'll recover.

Frisk, Asgore, Toriel, and Undyne talk in the living room about Betty. They ask Frisk why he didn't tell them about Betty. Frisk apologizes shortly before Gaster enters the room. When Asgore attempts to get

an update on Sans's condition, Gaster is unwilling to tell Asgore and instead tells him "not worry about matters that don't concern him". They discuss defeating Betty. After a brief conversation, Asgore has a realization that Betty is a spell... a curse, perhaps. Though they don't know it yet, Agate is the one behind the spell. Meanwhile, Gaster looks at Frisk and has a flashback of Frisk's time while committing Genocide before coming back to the real world, Frisk seeming unnerved by Gaster studying him. However, others do not notice. Gaster says Toriel and Asgore must save Asriel, corrupted by HATE, while Undyne is told to handle Alphys and save her from Betty. However, Dr. Gaster does not know Undyne was the one who killed Alphys.

The city suffers an explosion, which drew the attention of the monster crew that is fighting off the remaining pink creatures. One of them exclaims, "We need to go right now!" A little girl is injured by one of the pink creatures. It is destroyed by Ronan in an incredible burst of power, who then tells the girl to get into the school.

Frisk. Betty says she was excited to fight all of them, but that she wanted to only fight Frisk and finish what they started. As for Toriel and Asgore, they had to fight their son, Asriel, whose HATE is aggravated by his turbulent history with his parents. Asriel is the first one to attack in the battle, hitting Toriel with his "Shocker Breaker" attack. Then Frisk and Betty start fighting, and Betty notices Frisk looks terrified. Betty asks if Frisk is scared because of her new appearance or because he

. I'll be fine." Both Toriel and Asgore worry if they will lose Asriel again. Frisk then asks Gaster to talk in his lab.

Frisk and Gaster talk about Dr. Gaster's failed experiment due to a lack of determination. Frisk, realizing he is the vessel of this determination, asks Gaster to redo that experiment. Gaster asks if it is to fix his condition with Frisk nodding in response. Gaster warns Frisk that he may not be able to return, especially because of his condition. But Frisk says he's willing to accept that.

Frisk confesses that he lied to Chara about the "ghost following" in the Underground, and what will really happen is that he will be erased from existence (Frisk was glitched so if he were to remain in the timeline would become more unstable and erase itself eventually) and Chara will lead a normal life. Chara frantically protests, as he replaces Frisk. Eventually Chara's own memories are altered, he begs Frisk's to stop, saying he doesn't want to forget him, but Frisk saves changes. This changes everyone's memories, sends Chara to the Surface in Frisk's place, and ultimately results in Frisk's blotting out from existence. Frisk's final words are, "Keep my promise."
