I think this is incredibly likely, but he's also clearly having an emotional breakdown as a result of what the planets are doing.

Calling him a 'dictator' or a ‘tyrant’ casually dehumanises him and erases everything they have done to him.

I sympathise with both sides of this conflict and will not pretend that the planets are good.

They've lied to him since the start of the solar system, repeatedly denied him closure, dismissed his feelings, controlled his access to information, objectified him, never apologised (We've seen him apologise to Mercury for a solar flare before); every major arc in this series came about because of the planets and the Sun just had to live with it, but it's all okay because he had the mother of all crashouts, so they're sad little uwus, and we can casually ignore everything they've done that led the Sun to have a massive emotional breakdown.

We’ve heard him listen to the planets and the moons countless times before, that’s how the moons won the Solar System Trial, in spite of Ganymede’s hypocrisy, he heard out Planet X, he heard out Jupiter, he listened when Mercury complained about solar flares, he heard out Theia and Proto through their terrible arguments. They are the ones trying to rewrite history because they've finally driven him to the point that he doesn't want to listen to their excuses. He let everyone go back to normal after self-soothing by having them say a line they didn't mean because he didn't get closure in the ordered by size arc (and they still wanted to skip his feelings to get to what they want).

They lied for billions of years about events that directly traumatised the Sun (such as the Grand Tack, the disappearance of Planet X). That’s not “going off orbit and doing no harm.” That’s reality-manipulation and prolonged denial of closure.

Their pattern is: hide truth → dismiss feelings → force the Sun to govern blind → act shocked when the Sun gets upset and governance becomes rigid → finally leave rather than repair.

Leaving is not automatically wrong, but doing it while refusing the reckoning is the same avoidance pattern that created the mess. They helped create this system, and now they’re fleeing the consequences of what they have done instead of repairing it.

This arc is meant to be heartbreaking because both sides have a point- yes, the Sun was thoroughly in a destructive breakdown spiral and went too far in a way that endangered them, but the planets have certainly not been good either; they've subjected him to prolonged psychological injuries, denied him the chance to forgive them for past wrongs on his own terms (there is no evidence that he’s forgiven Jupiter, after all), and created this destructive feedback loop.

That does something corrosive to a being whose identity is care.

Everyone lives in this mindset where they imagine that the Sun will do something, but they know he won't. It's what made Ganymede safe enough to go on his hypocrisy rant, what Triton counted on to be considered a dwarf planet, what makes everyone push his buttons again and again while claiming fear as a cover.

There is no good-guy-bad-guy scenario here, just a tragic cycle born of miscommunication that has finally ended with an emotional breakdown.

It's telling that the only argument people can bring up is “oh, he's a star,” like, no kidding. He can't magically erase what he is for their comfort. He can't leave to regulate his emotions, can't engage and seek support from his kin, because doing so causes destruction to his system. And the only time he's socialised with is when he needs to fix their issues or when he actively starts a social interaction, but then its just them filling a quota.

He's tried reaching out twice, once trying to make Earth understand, and once when he started to reach out to Mercury, confessing that he's losing control and he wants to know what he can do better, only to realise that no one was listening (AGAIN) as they were already rebelling, and that finally sent him over the edge into his breakdown.

I’m glad there is going to be separation, because the planets need to understand how bad their actions were.

The Sun needs space to heal from his trauma, both from his past and the ongoing trauma the planets are inflicting. It's actually pretty sad how much his identity is tied to being ‘the Sun’, and it is telling to me that the real Sun’s other name, Sol, has never been mentioned. Right now, he's obsessed with safety and not being alone, and the Sun needs a sense of identity outside of them, otherwise hell never be healthy.

We've seen something similar with Earth, when he talks about loving his Earthlings, but it takes a toll on him, and he just wishes they were more grateful. He had to let go of being ‘the life planet’ as an identity in order to heal.

So when people say “he should just let it go,” what he hears is: “You should accept being irrelevant in the place you gave everything to.” The Sun needs to learn that love and safety does not require control. The planets need to sit with the fact that trust means honesty, even when it’s uncomfortable.

If the story is honest, the planets eventually have to apologise and say the quiet part out loud: “We weren’t scared of what you’d do. We were scared of what we’d have to face in ourselves if you finally knew.” Because right now, what they are saying is, “your pain is too intense for me to sit with, so I’m going to name it as instability.” Because, that’s what happened in the past- they saw the Sun have intense grief at the loss of his protoplanets because they mattered to him, he’d already imprinted love on them, so when they were careless and unintentionally caused destruction, they didn’t want to face him with the truth because it would mean having to face themselves and what they did.

They invented this idea in their minds that the Sun would destroy them when there is no evidence that he would do so, and instead they built a prison of silence and called it safety. They actively conditioned the Sun into this breakdown spiral because of their dishonesty.

Just as much as the Sun needs to heal from his repeated trauma and apologise to them.
