PetriGrof

PetriGrof is the het ship between Betty Grof and Simon Petrikov from the Adventure Time fandom.

Canon
Betty Grof was first seen and mentioned in "Holly Jolly Secrets," when it was first revealed that Ice King used to be Simon Petrikov. In the episode Simon describes the way he put on the crown as a joke to amuse Betty, only for everything to go horribly wrong. Having blacked out while under the influence of the crown, he isn't sure what happened. The only thing that he seems to be able to recall is that she had seemingly disappeared before he recovered from the effects of the crown. This would be explored in both the cartoon and the comics later on. The two were together in a steady relationship more than a thousand years prior to the main events of the original series. It is repeatedly said that Betty was Simon's fiancee in the original series, although in some side material she had also been referred to as his wife or as his girlfriend on rare occasions.

Adventure Time (2010-2018)
In the episode "Broke His Crown" it is revealed that Betty and Simon first met when they both reached for the same book in the library. Simon let Betty check the book out first, and Betty left a note in the book for him because she knew Simon would check it out next. Simon refers to this note as "The funniest, smartest note I ever read." Shortly afterwards in the episode "Temple Of Mars" it is also revealed that Betty met him the day before her trip to the Australian outback, but the next day she decided that she wouldn't take her trip as a result of meeting him. Instead, Betty decided she would help Simon search for the Enchiridion.

Some unknown years later the two become engaged, and Simon would later travel to Northern Scandinavia where he purchased a crown from a old dock worker during his career. After coming home with the crown he put it his head to make Betty laugh, but instead it caused him act on the impulses of the crown and all it's previous wearers. This frightened Betty, which caused her to run from him. In "Holly Jolly Secrets," Simon says that he would never see her again. However later, the series shows this event from Betty's point of view in the episode "Betty."

When Ice King's crown is drained of magic from an anti-magic wizard, he becomes Simon again. But without the crown's magic, he is now dying as he had lived an abnormally long life. With his identity and lucidity returned to him, he uses what time he has left to create a time portal to communicate with Betty and make amends for whatever he'd said or done to her while under the influence of the crown. With the portal opening shortly after she tried to hide from Simon in the past, Betty is then greeted by Simon from thousands of years in the future, who is talking to her through the portal. Simon tells her that he wanted to apologize for his behavior as a result of the crown's corruption, and properly say goodbye to her since he never got the chance because he never saw her again after that.

Betty initially finds the idea to be odd and out of character for her, until she discovered that he was cursed by the corruption of the crown. With only so much time left to speak with the future Simon, seemingly unburdened by the effects of the crown, she concludes that she must have left Simon of the past to be with the Simon of the future. She jumps through the portal, leaping into his arms and the two kiss. Creating a stable time loop, this would become why he never saw her again. However, Simon almost immediately collapses into Betty's arms and tells her that he is dying without the crown to keep him alive. Realizing that she could possibly be his only hope of permanently curing the effects of the crown, Betty tell Simon she'll fix the crown to buy herself enough time to figure out how to fix him. She then steals a magic carpet and later defeats the anti-magic wizard that was absorbing all of the magic. Simon is then turned back into to the Ice King as the crown's magic is returned, and Betty flies away on the magic carpet to focus on her new goal.

Betty begins to research wizards, magic, and the effects magic has on it's users with the hope of discovering a way to save Simon. Discovering MMS, or Magic Madness Sadness, she finds that there is a strong correlation between madness and sadness in those who use magic. These findings would become relevant in "You Forgot Your Floaties," where she seemed to have taken an apprenticeship under Magic Man to research him and in exchange for her help in a experiment to make him more powerful. It goes horribly wrong due to the interference from Finn and Jake. During the process of the experiment backfiring, Betty ended up receiving all of Magic Man's magic, and likely his madness and sadness as well. This resulted in her becoming a wizard.

She would continue trying to save Simon and cure him of the effects of the crown for the rest of the series, for better or for worse. Following the end of "You Forgot Your Floaties," she would try many different schemes to turn Ice King back into Simon. This would eventually culminate in the series finale, "Come Along With Me," where she ends up causing the apocalypse in the hopes of being able to use GOLB's power to return Simon to normal. In the the process the two of them both regain their lucidity, and Betty realizes what a huge mistake she made. Ultimately, she sacrifices her existence to fuse with GOLB and end the apocalypse. In the process, she is finally able to achieve her goal and restores Simon to normal but at a cost.

Adventure Time comics (2012-2018)
The relationship between Simon and Betty is plot relevant to a four issue arc taking place in issues #16-19. Stumbling across a dungeon he built with Hunson Abadeer, Ice King finds a photograph of Simon with Betty in a chest in its depths. Having a moment of lucidity where he remembers Betty, he then tries to leave a beacon with the photo in hopes of coming back to it later and remembering again. He shortly returns to his usual faculties of insanity, though this is not long lived. Later when The Lich is released during this arc, Ice King is trapped in the illusion of his greatest desires along with Finn and Jake.

As long as he was within the confines of his illusion, Ice King remained completely lucid. In this state, he comes across an aspect of the illusion taking on the form of Betty. The illusion of Betty was depicted as being trapped within the dungeon, chained to the walls, calling to Ice King for help. Seemingly reunited with Betty, Ice King immediately frees her under the belief that she is the real Betty. Later as Finn and Jake break free of their illusions and try to persuade Ice King into realizing the truth, he is too stubborn to believe them as he enjoying his momentary lucidity and the belief that he's been reunited with his fiancee.

Desperate to prove that the illusion is the real Betty, he asks her to recount their first "official" date. The illusory Betty then describes the two going skating for their first date, even though Simon apparently did not know how to skate. She claims that Simon kept falling over and over, but refused to admit he didn't know how to skate, and that she found it sweet. Ice King never refutes this, indicating that it was something he believed to be true. However, Finn and Jake begin to rap about feelings in hopes of forcibly breaking the illusion since Ice King refused to take their word for it.

As the illusory world begins to break down, so too does the illusion of Betty. Screaming in pain, the illusory Betty begs them to stop. Ice King attempts to force them to stop, but when they refuse the vision of Betty begins to crumble while pleading that she doesn't feel fake. As Ice King reaches out to her, telling her she's just as real as he remembers, she finally crumbles to dust in his hands. Initially lashing out at Finn and Jake for destroying her, he soon calms down and leaves the illusion to challenge The Lich instead.

After The Lich is defeated and the trio earn the spoils of Ice King's dungeon, he claims a heart-shaped gem for himself while half-lucid. He then places the gem in a niche on the interior of his crown, in memory of both the real Betty and the illusion of her.

Adventure Time: Marcy & Simon comics (2019)
Taking place after the events of the original series but before the timeskip another thousand years later, Marcy & Simon is a continuation where Marceline and Simon embark on an adventure together. The storyline eventually culminates in the two rescuing Betty from her existence as the new GOLB, reuniting Simon and Betty for good. It seems as though this comic and it's storyline is either no longer canon as of the release of Distant Lands, or at the very least taking place in an alternate timeline to the main series.

Adventure Time: Fionna and Cake (2023-)
As this spin-off has not aired yet, it is not yet clear in what way the relationship between Simon and Betty will be explored. However, one of the trailers released for the new series features several shots of Betty. One of which is a scene where Simon can be seen grabbing Betty by the wrist while they are both blushing. It is not yet clear what the context is, or when in their lives it may be taking place.
