plotting and making conflict

I just chose one of the examples and tried to expand on it, I hope that is ok.

An eccentric substitute teacher subverts the 2+2=4 universe of her fourth grade students by introducing them to “substitute facts” (such as 6 x 11=68), Egyptian cosmology, and the curse of the Hope Diamond. One afternoon she explains the use of Tarot Cards, and predicts the early death of a particular student. (Charles Baxter’s “Gryphon.”)

What is at stake? The student's, Suzy, life is at stake, but if it gets saved, you risk upsetting the balance of the universe.

"Alright students now watch carefully." Ms. Shinebocker started mixing the Tarot Cards. This would be the last lesson she would have a chance to teach her class. Their regular teacher was going to be back tomorrow so she had to go out with a bang. The lights dimmed, but nobody touched the light switch. The desks scraped across the floor in a circle, but there was nobody there to move them. Ms. Shinebocker stared wildly at the cards in the center of the room as they begun to smoke.
With a shaky voice little Suzy was the first to speak up, "Ms.Shinebocker, are you ok? I don't like this."
Ms. Shinebocker's wild stare was then diverted to Suzy. With eyes wide she pointed at her, "it is you! You are the one little Suzy! You are going to be dead before the week is over!"
The class gasped. The lights went back to normal and the smoke emitting from the cards was beginning to clear. Ms. Shinebocker's eyes closed, and when they opened back, she looked determined. "Alrighty kids, what did you think of that? The world is a magical place indeed isn't it? Ok now, how about we get our desks back in their rows and do a little reading huh?"
All the kids looked around at each other. What just happened? Jim was about to find out. See, Suzy was Jim's sweet thing and he always protected her against everything, and Ms. Shinebocker would be no different. He raised is hand, but before Ms. Shinebocker even called on him he yelled, "What do you mean Suzy will be dead before the week is over?"
Ms. Shinebocker waved her hand, "Oh Jim, so valiant even at such a young age, but even you will not be able to save her. It is the future Jim, it is meant to be. If it is to be changed, then the balance of the entire universe could become upset. I sure am sorry little Suzy, but it is your destiny. It is hard to see it now, but your early departure from existence is meant to be for the greater good of things. I am truly sorry though my dear."
Jim had to do something, but Ms. Shinebocker seemed too set in her ways to help him. He had a plan, "Yeah right, hah, I bet you just made all of that stuff up huh? You really have been a funny sub Shiner." Ms. Shinebocker looked shocked, good Jim thought it's working. "What does this future of yours look like huh? How does little Suzy die? You can't see that no way!"
"Oh little boy! I can too see the future and everything I have shown you all has been real. Don't think you are going to fool me that easy though boy, I will not tell you how Suzy dies, as I have said, the fate of the universe depends on her death. You screw that up, who knows what the future could turn out like. I am not putting that up to chance, I am not going to be the one to screw up the balance."
Jim thought he had done it but he failed. He couldn't imagine a life without Suzy. He couldn't let her die.
