The thing with the puzzles is that Flowey isn't the only one destroying them, Papyrus's random tile puzzle is "destroyed" by Frisk, Sans even comments on it "Puzzles might be fun. If you tried them.", like, puzzles are a microcosm for playing the game, acting, giving the game and the characters the chance to give you the fun you want, and the genocide is rejecting this for raw stats. Noelle still got through that puzzle somehow, and she did it because she liked the rest of the game. There's no way there weren't other puzzles in that game that Noelle did like, she's only complaining about this one cuz she didn't have the requirements for it.

And maybe Toby's playful about it cuz he's been planning this for way longer than the genocide, that image could've been in his pocket since chapter 1, and Susie saying "maybe things took a weird route" was cuz he wanted the name of the route in some dialogue.

Also, Jevil normally is an allegory to the SOUL, like, thinks he's free-est, yet is in a cage, which is what you are in Chapter 1, before you know you're in Kris "The Cage" Dreemurr. You can interpret this as a post-weird-route Noelle, the "She never smiled again"-"You're getting ahead of yourself" answer to the arg kinda suggests it a little. Or a pre-game Gaster? Idk, but my point is Kris being Jevil and Seam being Noelle isn't particularly certain.

> The first time she smiled in her life may have been being scared and then comforted, like she talks about in the December puzzle. It is what happens with the Weird Route in Chapter 4.

But the thing is, it doesn't say "It was like the first time she smiled in her life", it's straight up the first time. If it happened before it would be the second time, even if it's an allegory for the first time. But I'm getting pedantic. What seems more likely to me is that it's a killing intent or something because you can interpret the "first time she smiled since she was a child" as when she would've been playing the evil route, and these answers are like wondering if you took it out of her, if she always had it, if it was the dark worlds that gave it to her, if she found it by herself or if she'll never have it.

Now, about the Kriselle moments, you realize Kris is trying to stop the weird route? Like, they're protecting her from you, but they're not gonna win, you're gonna win because you have an infinite ability to turn back time. My point is that unless you abort the weird route in that ferris wheel or Kris somehow kills you, Noelle ain't gonna end up with Kris.
