This girl outright dared the Sailors to kill her while shielding Nephryte. Not to mention what she pulled right in the next episode.

Naru should've been a Sailor Guardian. She would have done a much better job than her BF Sailor Scaredycat.

With Chapter 6 closing in, I have a proposal on how things will go down.

Let's go over the clues first: Toby said Chapter 5 was the last "fun adventure" and Chapter 6 will be much easier to develop, meaning no new mechanics like the climbing in Chapter 4, the platforming in Chapter 5, or all the minigames in Chapter 3. There also will be no more Eggs, no more Shadow Crystals, most major Light World subplots were already resolved in Chapter 5 (at least in my opinion), and the Weird Route skips Chapter 6 completely. Chapter 6 will be what I call a "lore fodder", similar to Chapter 4. The Chapter 4 Dark Worlds also had no unique antagonist, instead focusing on us chasing after the Knight. However, Chapter 4 still had a longer Light World segment, a Secret Boss holding a Shadow Crystal, an Egg, and Weird Route content. So, instead of 3 smaller Dark Worlds similar to each other (the First, Second and Third Sanctuary), why not have 2 different Dark Worlds: The Holiday Mansion and the Shelter. That way, the lore dump of the Chapter is also evenly split.

Then there’s the story: Susie already got the "cop's badge" code from Asgore's flower shop (0915 199X) She also knows the "pine tree" code (1225) is in Dess's guitar, she just needs to look at it a second time, since she couldn't memorize it before Carol interrupted her. Lastly, the "church symbol" is the Delta Rune itself. Now, we already found a code in the church (2202) written on the back of the fire extinguisher. But some people argue that it isn't the code, it was just a code to a locked door in Chapter 4, and we need to get a separate code in Chapter 6. Okay, but from where? Neither of the proposed Dark Worlds (the Hospital and the Holiday Manor) have that code, and no other would unless we recreated the Dark Sanctuary.
This leaves us with 3 possibilities:
- We already have the code (2202), or
- Susie steals it in a Light World segment, or
- We get it from Toriel after she gets filled in and realizes that's the only way to save Asgore

Toriel having the last code would actually make sense. She's deeply religious (the Delta Rune is on the front side of the Dreemurr house), she's the leader of the church choir, and the Knight tried to abduct her, and the 2 kidnapped victims (Asgore and Undyne) had a code of their own.

Here's what I propose: On Monday, Susie tells Noelle that the Dark Worlds are real and shows her around Castle Town. However, it's not long before Noelle breaks the news that Rudy has fallen down. The doctors gave up on him, and he's now at home, while everyone is preparing for the funeral. Toriel is also at the Holiday Mansion at that time, as while she had a falling out with Carol, she's still on good terms with Noelle and Rudy. After realizing how the Dark Worlds work, Noelle rushes back home and creates a new Dark Fountain in a desperate attempt to save her father. This will be the creation of the Holiday Mansion Dark World, the Ice Palace. This is where the walls everyone put up come crashing down. Rather than having a new antagonist (like King, Queen, Tenna and Flowery were in the previous Chapters), Carol will instead take charge in a final attempt to keep Susie away from the guitar. Meanwhile, Susie finds out Kris was a double agent this whole time, although she already had her suspicions, and knew Kris and the Dreemurr family in general has been going through some tough times due to what she learned from Flowery and Asgore in Chapter 5. Toriel and Rudy (assuming they had no involvement in Carol's conspiracy before) had to be kept in the dark up until this point, but things are different now. Noelle making this new Fountain was something no one expected, because of that, the Knight is nowhere to be found, and with everyone else realizing she's gone too far, Carol is left wide open. Rudy helps us retrieve the guitar, saying a proper goodbye to Noelle in the process, and given that she still cares about Asgore, Toriel will give us the final code. Once we seal the Fountain, it will be a race against time as the Knight is about to perform the sacrifice on their own in Carol's absence. Everyone rushes into the Chapter's second Dark World, the Shelter. This is where we finally learn how the incident happened, and at the end, we find Undyne and Asgore. This time, the Knight will be out for blood, as both sides make one final push to stop the other. Despite winning the battle, we're too late, and the Roaring starts.
