Question Is there ANY way to retry the fight with the Knight after losing?

I've finally got the chance to fight the Knight and am currently stuck in the fight (shocker, I know). But the thing is, after losing it is such a pain to have to close the game, get in, watch the whoooole cutscene with Tenna being disarmed over and over again, it is incredibly boring.

And I get it, if you lose the story keeps on going because Tobias the Fox wanted to the whole "the party is not strong enough to defeat this guy yet", but like, is there not anyway to retry it without closing the game? (I am playing on PS4)

# (I FORGOT TO ARRANGE THE ATTACHMENTS AAAAAAAAAAAAAA!!!!)

I like these ones more than my initial design. I wanted to give Aqua her beeg, oversized sleeves back, and came to a comprise of giving her dark, aquamarine hair, instead of feeling the need to pick a side between fully black, or unnaturally/slightly off-putting imo aquamarine hair.

I also had no idea what the hell I was doing for UT!Seth. My Undertale sprite for them was harder to read than their original sprite, especially with their thick purple collar on top of what seemed to look like a button down. In this updated sprite, you can clearly see they are wearing a scarf on top of a cardigan. I also prefer them with brown skin, instead of having the same skin tone as UT!Aqua. I also thought it be cool to give them highlights in their hair, to parallel how Deltarune Seth has purple and black hair. (unless its a hood because many people think its a hood, and I do admit it does look like that in some sprites. All I can say is I hope Toby Fox or someone working on Deltarune posts concept art Seth so we can stop debating this.) I know their sprite is a tad bit asymmetrical,

Most of my headcanons still apply to them (e.x. UT!Seth having a deadname, UT!Aqua and Seth being half-siblings, Aqua and Seth getting into a fight (Aqua tried to look inside Seth's notebook one time), causing Seth's notebook to tear, Aqua having ADHD and dyscalculia, Aqua having a missing tooth where her Deltarune counterpart has a prominent fang, Seth having messy handwriting/messy notetaker, and being obsessed with human/monster history, and birds for whatever reason, etc), but I don't have a set time period for them expect for post-Chara I guess, and I didn't really like my explaiination for how the entered the underground. Do you think you guys can help me come up with some headcanons for them? :3

Discussion Papyrus Knight is officially deconfirmed.

Post image
64 Upvotes

We all know that Papyrus Knight has mostly been a joke theory since its inception, however some have somehow taken it seriously and bent over backwards to justify it, no matter how little evidence there is or how many things are working against it, it should have already been dead in Chapter 4 with what Ralsei told us about Dustners but the discourse still continued, but now with multiple pieces of information Chapter 5 presents I can now announce without a shadow of a doubt, Papyrus Knight is absolutely dead, debunked, not possible, not plausible, hard deconfirmed and not a candidate anymore.

It was already a major stretch to assume the one that hasn't shown up in game at all yet, doesn't know what the sun is, has never met a human before Frisk (yet somehow is working with Kris if he was the Knight?), and only moved into town with Sans very recently is somehow working with Carol and wears fake antlers as a sign of allegiance, somehow knows the Shelter codes, and is willing to hurt the fun gang and kill darkners for some reason, all based on vibes and making up ways it connects to the game's "themes", the Knight's skeletal appearance (but other relevant parts of its appearance like the antlers mean nothing because it's a shapeshifter unless it supports my theory, then it matters), the fact that he isn't in the house ONCE in Chapter 4, and a motif in Dating Tense that also appears during Alphys' date. That's it. That's all they have.

However in Chapter 4, we learn from Ralsei after he crumbles the Sound of Justice statue, that Susie's Gerson came out all wrong and he can't be even brought back to Castle Town (with the fountain made of pure darkness) because "Darkners patterned after the memory of a loved one can only exist in specific darknesses". People have tried to misinterpret this line as "Oh it's just because Gerson is his favorite author, that's how it was able to recreate him" even though the clear subtext of what Ralsei said was that it has to be someone the fountain maker had to have known personally, not just some loose ephemeral one-sided parasocial connection with someone you've never seen before. Sans and Papyrus moved in long after Gerson died, meaning they never met him in person, much less had an opportunity to have a personal connection with him, whereas Asriel and Dess had him as a teacher when they were Kris's age, and the way he's portrayed as a snarky mentor figure lines up with that relationship far more. But people still managed to twist this obvious deconfirmation in ways that still justified their theory so let's move onto something that can't be ignored!

I talked about how Sans and Papyrus only moved in recently, but how recently? Well from Chapter 5 we have a hard cutoff date, last year's festival. Kris notes as Susie and Noelle are on the ferris wheel that someone else used to run it, and Susie notes when inspecting Sans and Papyrus's house that she doesn't really remember what was there before but that someone else used to live there, a completely different building, and she lives just down the street from their house, as if Sans saying they just moved down there wasn't enough in Chapter 1, residents that have lived there for years indicate their arrival was recent.

Now that that's been established, we find in Chapter 5 through Asgore's notes that he found a Black Shard at the scene of the crime Dess dissappeared a LONG time ago, years ago, a Black Shard matching the ones he found at the library and church (also confirming the Knight made these two fountains), a dark world a long time ago made by someone possessing a black shard HAS to be the Knight, and since Sans and Papyrus only moved in less than a year ago, and Papyrus Knight's supposed motivation is working for Carol to bring Dess back, it's literally impossible for him to have been present and if he was somehow, it doesn't line up with this supposed motivation at all.

So with that being said, Papyrus Knight is officially out of the running in terms of being considered an actual candidate.
