Really Small Problems starts with King's bread puns, so obviously, it's already crucial to the emotional arc of the finale. But knowing that the Titan was watching that day, do you know what else the Titan must have noticed, and how that makes the finale so much more impactful?
[ID from alt: King talking to a disguised Tibbles, then Luz kissing King on the forehead after they reconcile. End ID.]
In the episode, King gets used as a pawn by Tibbles — who preys off of King's desire to spend time playing with Luz — and as a result, King puts Luz and her friends in a lot of danger. But Luz, while initially angry, realizes that King was being manipulated, not malicious — and at his absolute worst, just an irresponsible kid who really wanted to spend time with his friend — and she reconciles with him, leading to their bond becoming stronger than ever before.
But hey, for no particular reason, remember what the Titan's greatest regret was, again?
[ID from alt: a projection by the Collector, of the Archivists reaching out to the Collector, then a projection of the Titan glaring menacingly. End ID.]
When the Collector was being used as a pawn by the Archivists, who were the ones who really killed all the Titans, King's dad didn't realize the truth until far too late. Rather than talk to the Collector and try to understand, let alone reconcile, Papa Titan lashed out at the Collector for their perceived betrayal — imprisoning the Collector, thereby plunging him into traumatizing isolation, for millions and millions of years. It's the Titan's worst mistake. The Collector didn't deserve anything like that — the Collector was just a misguided little kid. But the Titan had let his rage consume him. And now, slain by the Archivists, the Titan can no longer undo her mistake.
So... fast forward to when the Titan's own kid has finally hatched, and started to grow up. The Titan sees his kid make a friend in Luz, whom the Titan already likes, because she was kind to King and respectful to the Isles. But then — the Titan sees her own kid do something misguided. The Titan sees his own kid put his friends in danger. Only... instead of fallout from Luz's feelings of betrayal, the Titan sees Luz actually reconcile with King. The Titan sees Luz recognize that King didn't want to hurt anyone. In other words, the Titan sees Luz avoid repeating the Titan's mistake.
Of course, dealing with Tibbles is far, far lower-stakes than dealing with genocidal Archivists. But what the Titan sees is Luz proving that she can be levelheaded, and forgiving, and most of all, trustworthy with the challenging decisions that the Titan himself has messed up before. Luz finds her last two glyphs rapid-fire after this episode, after the first two were comparatively slow-going. She still has to work for them, by being attentive to nature and to magic, but that change in pacing isn't a coincidence. The Titan is selective about who can be trusted with glyphs — but Luz earns that trust. By being kind to King, first and foremost — but even more specifically, by extending understanding and forgiveness, instead of blame, to a child who had just wanted to play.
And that all culminates in why the Titan trusts Luz to wield the full power of the Boiling Isles in the finale. It's why the Titan believes Luz is a genuine and kind person, who can defeat Belos by force without ever being or becoming as bad as he is — because Luz does give people second chances, and resolve things non-violently, when people aren't as malicious or set in their ways as Belos is. Because Luz gave a second chance to King, and even gave a second chance to the Collector — thus, doing what the Titan couldn't. The Titan trusts Luz not to give into destructive, punitive options — neither killing, nor imprisonment — unless there is truly no other option, in which case killing Belos isn't punitive or retributive in ideology; it's just self-defense.
So, when the Titan makes some of her final words a bread pun, it tells King and Luz and the viewer so much. That the Titan was watching the whole time — but that the Titan was watching Really Small Problems, specifically. That the Titan watched King mature, and the Titan watched Luz forgive him. The Titan watched and made reference to a story about second chances and reconciliation working — because they do work, most of the time, and the fact that Belos is the rare exception is crucial to the message of the finale.
And in a more meta, ironic way — yet one that I'm sure the writers were aware of — the Titan was even watching what some fans called a "filler" episode. But Titan cared so much about Luz and King's development within. And what a brilliant way to tie the whole show together! What a good tribute to the value of gradual character development! And to rewatching a show with fresh eyes, now metaphorically from the Titan's perspective!
It changes everything. It makes you appreciate Luz and King so, so much. It's such a subtle, beautiful writing choice. And the Titan is such a beautiful character. Really Small Problems is not a skippable episode. It always had good character development, but the way it's utilized and recontextualized by the rest of the narrative is nothing short of brilliant.
