During the Chapter 3+4 Era, there was a fic I really enjoyed, "I shine only with the light you give me"

In which the SOUL talks to Kris using Asriel's Computer. At one point the SOUL ask Kris how they want them to interact with Ralsei, and they reply with,
"He’s a nice guy. Deserves good people, good friends. Susie likes him too. Keep letting me hang around him. He’ll need it.”
Kris thought for a moment. “But tease him a little more. Rile him up. Make him figure out what he wants and make him stand up for it. He’ll need that too.”
And then, Chapter 5 rolls around, Kris makes the dark fountain, and then this guy show up.
And at first, I despised him, cause of how much of a jerk he was being. Then I realized, that was the point, that he was doing what the fic Kris said. After figuring that out, I still don't like Flowery, But I do hold some respect for him.
