So I saw this prompt and started laughing really hard as the wheels in my head started turning, so this chapter is for bstix with the prompt: "Regina attempts to teach Emma how to make magical fireballs, with disastrous consequences"

"I want you to teach me something," Emma said, plopping down onto the couch next to Regina.

"Like what?" Regina asked.

"I don't know. Something magic related," Emma said. "I'm better at my magic now, so maybe you could teach me something harder than the basics."

Regina's eyes lit up as she smiled wickedly. "I have the perfect thing to teach you," she said.

"Uh oh," Emma said. "You have that sparkle in your eye. The last time you had that, you stuck me in the middle of a bridge hoping to 'teach' me to use my magic."

Regina laughed. "I promise that this won't be like that," she said. "This will be a calm training session. There's something that I HAVE to teach you."

Regina and Emma stood in a clearing in the forest. "If I'm learning to create a fireball, shouldn't we do this in a place less flammable?"

"Probably," Regina replied. "Consider that more incentive to control it."

"I knew you would do something like that," Emma grumbled. "You meanie."

Regina chuckled. "You'll be fine. It's like doing any other magic. You have to feel the fireball before you can create it. Imagine what it would feel like to have a little ball of fire in your hand, and create it."

Emma rolled her eyes. "Of course you have to make it sound a lot easier than it actually is."

Regina smiled before gently taking Emma's hands. "You can do this," she said. "You have control over your magic now." She squeezed Emma's hands before stepping back.

Emma nodded before taking a deep breath. She closed her eyes and envisioned what it would feel like to have fire in her hand. Feeling warmth in her palm, Emma opened her eyes and smiled. A fireball was resting perfectly in her hand.

"I did it!" Emma exclaimed. "Regina look! I did it!"

Regina laughed. "I see that," she said. "Now you need to extinguish it."

Emma pouted. "But I don't want to. Just look at how awesome it is." She moved her hand to show Regina, causing it to lightly touch a tree. The tree instantly caught on fire.

"Emma!" Regina exclaimed.

"I'm sorry!" Emma said. "I didn't mean to, my hand just lightly brushed up against it! What do I do? It's spreading so fast!"

"Calm down," Regina said. "Getting worked up could make it worse. Just envision the tree as it was before."

Emma nodded before picturing the tree without the flames on it. After several beats, Emma opened her eyes. The flames were gone.

"Oh thank goodness," Emma sighed. "That could have been a disaster."

"Don't worry about it," Regina said. "We'll just have to keep practicing."

Emma looked at her with wide eyes. "I'm not doing that again! Fire is dangerous by itself, but magic fire? That's just a disaster waiting to happen!"

"Come now," Regina scolded. "You have to keep trying. After all, practice makes perfect."
