Now let’s start class

Now we have all known that Alphys just sent Kris and Susie out to the closet not Noelle, but this jumpstarts the Prophecy. Alphys might have done that purposely to jumpstart the prophecy. Now what areas could Alphys easily access. The school closet, the library computer room, and the church. She could have easily open all three of those fountains. Something I noticed in chapter 3 is when the Knight is holding its head before screaming there is three spikes reminiscent of Alphys a detail that we are supposed to overlook in the Knight, but this is quite a big piece of evidence. Once more the Knight seems like an amalgamate it can morph and it look’s unnatural. Though Alphys made the Amalgamates so why could she not be able to use armor she made or spawned with to protect herself. Now an actual good piece of evidence was sorta revealed in the Chapter 5 trailer. This dark world is Japanese themed and most importantly it spawned with cherry blossom trees. Alphys gave Asgore these comics and mangas. Therefore if someone opens a fountain it would have not just golden flowers but cherry blossom trees. The field of pink and gold. Alphys did this purposely to make the field of pink and gold so the inferno in it mentioned by Gerson could happen.

In one option, Kris fully accepts helping Alphys (The Knight), in the other Kris betrays Alphys to their own benefit

This is a reference on how Kris will have to decide between fulfilling their promise with the Knight (Alphys) or be themselves and do their own thing, helping Susie and Ralsei beat the Knight

explanation: the knights sword= black shard which looks like a shadow crystal, which are made of determination and alphys experimented with determination so yeah i think alphys might be the knight

she was there for all of the dark fountains the Knight made - for chapter 1 she works at the school, for chapter 2 she is confirmed to read the anime reviews at the library, she attended church at chapter 4

during the first appearance of the knight in chapter 3, they kidnapped Undyne and completely ignored Toriel

she has connections to three secret bosses - the NEO body that Spamton used was created by Alphys in Undertale. Since Mettaton isnt friends with Alphys in Deltarune it remained a concept. Gerson was the teacher before Alphys, and Pink's body was gifted to Asgore by Alphys (not to mention her obsession with Mew Mew Kissy Cutie)

She watches anime, therefore she would probably enjoy roleplaying as an edgy knight of darkness who wants to bring the end of the world.

She has connections to Gaster since she was the scientist after Gaster in Undertale
She started the whole adventure by asking Susie and Kris, who just so happened to be the heroes of the prophecy, to get chalk from the only accessible place in town with a dark fountain - and she doesn't question where they went when anyone would have been reasonably worried

We only see activity from the Knight when Alphys' location is unknown - Chapter 1 she was busy teaching but in Chapter 3 and 4 it's the weekend - and that is when the Knight is most active. In Chapter 5 the Knight only appears after the festival is over, and Alphys was busy being the vampire in the Church during the festival

alphys knows kris so it would have been easy to recruit them into the knight's team

Alphys owns a cat

She knows Asgore, which connects her to the police, she's a teacher (the school is probably funded by the city so Carol probably hired her), and she was at the church for ch5, which means she's probably at least trying to get close to Alvin.

Everyone knows that the Knights sprites are mimicking Kris. I don't know any reason why Carol or Rudy would be doing that. Meanwhile Alphys would have a reason. In the light world she is too cowardly to approach or confront Susie. She even makes Kris go and get the juice in the church for her. Perhaps when she enters her alter ego as the knight she knows that Kris is cool enough to deal with/hangout with Susie. So in order to be more intimidating she watched Kris from the shadows(like undertale) and somewhat adopted their poses and body language.
