Eventually, the red flower is forced to meet with Kris and the party once more, but not before Noelle came along. Noelle had followed after Susie when she left to the fountain, but came across the red flower, and allowed it to climb onto her arm. She carried it until at last finding the party, much to their surprise. Kris immediately recognized the flower as the soul, stalking toward Noelle to reach for it. Susie notes on how pissed Kris looked to see that flower, wondering why they want it if they hate it so much. Noelle hesitates to give it to them, seeing as we were a flower with a face and Kris hates us, eventually deciding that it was our choice. Noelle says that her arm has started to hurt from our vines' hold on it, so staying on it is not an option. If we try to go to Kris, they immediately try to grasp us before Noelle pulls back her arm so that they didn't hurt us. Ultimately, in the end our only option is to travel on and through the ground. We give the party a bit of help, seeing as only we can cross the rivers and Ralsei doesn't want Susie throwing anyone for the bridge puzzles, and give buffs in battle, such as giving Ralsei a "cuteness buff" by letting him put us on his head or Kris an "energy buff" by using our vines to support their weakened movements. Eventually, the gold flower tells us off for going with the party to seal the fountain, and they have the other flower princes slow their path while they go to warn Asgore that his asylum is in danger.
Alright. We already know that chapter Five has something to do with a "field of pink and gold", is most likely set in the Flower King flower shop, and is set on the day of the festival. Here is how I believe is how the plot might go.
Kris removes us again, and thrusts us into the ground or puts us in a flower pot. It's not entirely an unbelievable notion that a Human SOUL can be capable of blooming into a flower, considering how little we actually know about souls, so hypothetically we could become a small red flower. We all know about the flowers in Asgore's basement, representing Flowey and the six human souls; however, not even the gold flower represents the red soul, as Flowey is soulless. Because of this lack of a red flower, as well as the likelihood that the flowers in the basement are prized or rare, Asgore brings the little red soul flower back to sit with the other seven. We overhear some dialog between Asgore and someone else, but we cannot tell what the other is saying or who they are. Asgore wishes them a good day, but the lights abruptly turn off. Our small form gains eyes, a small crown, and ability to move; we are suddenly in a dark world. Among the first that we see is Kris, stalking around as though searching. We must flee, but as we "run", we stumble across seven other flowers with small crowns; the flowers in the shop. They each have eyes and mouths, but simply treat you as a mute younger sibling, due to your smaller size and lack of a mouth. You hide amongst them from Kris as one speaks to you, welcoming you into the role of the tenth Flower Prince(as Asgore is the flower king, he already has two children, and we are the eighth prized flower). Some of the flower princes notice that you are entirely different from the other nine, and the gold one even threatens you to not go near the dark fountain. He knows what you are, and will not hesitate to attack in order to keep his kingdom alive.
