"Dad, can I PLEASE know how you're gonna train me to repel dementors?" Sarah asked as she was trying to catch up with her father. "Right now?" he reassured, "bloody hell, yes please!" Sarah pleaded, Severus smiled at her playfully and walked to the seventh floor. Sarah had a feeling she went through here before.
Room... Room of... Room of R...?Room of Requirements!

"Room of Requirements once again?"
"For these situations, it's better here."

A door burst in front of them, Severus nodded at Sarah. Receiving the message, she pushed the door open. The room looked challenging. There weren't any mirrors anymore, but rather like a office. There was a huge trunk in the very center, that rattled and shook. "Whats in there?" Sarah asked, "I guess a Boggart. We can't risk a real dementor." he told her then brought out his wand.

"You may be familiar with the Patronus charm?" he asked her, she nodded eagerly and brought out her wand too. "Can you show me, again please?" Sarah requested, Severus gave a low chuckle then waved his wand. "Expecto Patronum!" a silver doe burst out of the tip of his wand and pranced around them. And at the very last minute, jumped out of the window. "Well, I'll teach you how. But we'll practice without the boggart first to see clearly what your patronus is."

~~•~~•~~•~~•~~•~~•~~•~~•

After a while, Sarah was trying so hard to cast the Patronus. "Expecto Patronum..." But her voice seems to lose hope time to time since her head pounds too hard on the memory. "What memory did you think of?"

"The day when you bought me a new broom."

"Not enough, find another one."

After so many takes she plopped to the floor. "I can't. I'd rather have my soul sucked rather than tiring my butt off." she said, but something was making her uncomfortable, she realized her necklace was in the wrong position and fixed it. Until she found her memory. She stood up and brought out her wand. Severus looked up, surprised seeing her still up to train.

Remember when dad figured out I'm his daughter! Come on, Sarah! You can do this! The time when you won that bet! The time Aunt Joanne told me I was going to Hogwarts! It's either way, and you need to prove you aren't a coward! You've defeat a dark wizard and you can't produce a spell?! Come on!

Severus was looking in her mind, smiling at her memories. She tried hard, and didn't realize she shouted: "EXPECTO PATRONUM!"

To Severus' surprise, the spell worked. Light shone from the tip of her wand, and appeared was a...

Beautiful and Majestic lion.

It pranced around Sarah as she opened her eyes. "I did it!" she shouted in glee, jumping up and down. The patronus stopped in front of them, and roared loudly. Severus looked at Sarah who gave her a little smile. And in a few moments.... It dissapeared. "A lion... Curious..." Severus muttered under his breath. "Well, you're a bit tired out. You want to finish the practice tomorrow?" Severus suggested, as Sarah tied her hair in a ponytail. "Sure. Thanks dad!" And skipped towards their common room. "A lion..."

Severus went to his chambers and brought out a book. He started to find a page.... A ripped one. "Lion...lion...lion...Lion!" he said as he slided his finger from one animal to the other.
