"Time for an adventure," she smiled, "Dissendium."
The hump moved once again and the dark passage felt like it was inviting Serena to enter. Serena took a heavy breath and pulled out her wand. "Lumos."
The tip of her wand created a small light enough for her to be able to walk in the dark. The passageway closed immediately after she stepped inside.
"Well, that was rash," she mumbled as she realized that she didn't know how to open the entrance from the other side. Serena's excitement was so overwhelming that she did not spend too long worrying about how to get out and instead, she walked further into the dark discovering a lot of diverging paths.
There were paths that automatically lit up the lights on the walls then closes after she passed but she stopped in the midst of the dark when she felt the floor beneath her vibrate. There was also a faint sound of something gliding against the concrete ground she was standing on.
Serena was starting to freak out. She slowly lowered her wand and pointed it on the floor as if waiting for something jump on her but there was nothing.
"Look who's here."
Serena jumped from fright. She thought her heart was going to detach from her chest but she sighed in relief after recognizing the owner of the voice.
"Goodness! You don't know how happy I am to see you." she panted the gave a weak laugh.
"How on earth did you find this passageway?" asked Fred. All the three boys were also holding their wands with light on their tips.
"It's thanks to you, guys!" Serena grinned, "I just overheard the password when you were running away from Filch."
"Blimey, that wasn't like us to be so careless." George muttered while scratching his head.
Serena laughed at the statement. "Really? With all the mischief you've been playing, I doubt you have been not careless."
George grinned and turned to Fred. "What do you think Fred, should we let her come with us? She might get lost, you know."
Fred examined Serena and looked at Lee and George. "I still don't want to share all our secrets."
"I won't tell your secret, whatever that is! But if it's the map, I already know that so you don't have to hide it." she pleaded.
"I told you it's not just a map." Fred said in an offended tone.
Serena rolled her eyes. 'Why are they still hiding it?' she thought.
"Look here, Moore—"
"Serena." she corrected.
"Sorry," Fred said, "It's brilliant that you were able to enter the passageway and we're more than glad to share these information to other friends of ours but there are certain things we can't share that easily."
"Like your map?"
"Yes." all of them answered in chorus.
Serena sighed and surrendered.
"Alright, alright. Where were you going anyway?"
"A part of the passage that we haven't explored yet." George answered.
"Can I join you?" Serena asked hopefully.
Fred looked hesitant and the two just waited for his answer.
Serena turned to George, "Oh please, just this once! You said it yourself, I might get lost!"
"Fine." Fred finally agreed when George look at him.
"But you're not to share this to anyone yet." he added.
"Yes, sir!" Serena saluted.
The path they took was narrower than the others so the twins walked in the lead while Lee and Serena followed behind them. They continued to go further and Serena couldn't help but notice that the twins were not using the map.
"Er— are you sure where to go?" she asked.
"Of course we are."
"Why aren't you checking the map?"
"And reveal it's magic to you? Don't think so, Moore." Fred smirked.
"What's so special about your map that you don't want me to know?"
"We told you it's a secret."
Lee and George snickered then George patted Serena on the shoulder. "Don't worry, kid. You'll know it someday. After we explored every corner of Hogwarts, I guess." he laughed.
Serena didn't pay attention anymore. She felt another movement underneath the floors.
"Did you hear that?" she whispered to Lee.
"Hear what?" he asked with a puzzled expression.
Serena did not speak and tried to feel the ground again but it stopped.
"Wait a minute." Fred snapped and turned to George and Lee. They huddled far from Serena and she only heard faint mutterings and whispers. The three straightened up and look at Serena.
"I think we're lost."
"What?!" she exclaimed.
"Well, not entirely but that doesn't matter. What matters most is that we get you back to the exit."
"Just open your map already, if we're lost."
"You know we won't." Fred smirked.
Serena knew not to argue and let them lead the way again. She had a feeling these guys were going somewhere they didn't want her to join.
"How do you open the way from here?" she asked.
"Still dissendium."
A few minutes later, they appeared from the passageway and checked both sides for any sign of Filch.
"Let's go back to the common room." Lee whispered.
"As if you are really going back." Serena huffed, "I know you're planning to return inside. Just get on with it and I won't follow. I know you just didn't want me to know about where you were off to."
"Sorry, Serena." George looked sincere but had ahint of amusement in his face so as Fred and Lee.
"Are you going back to the common room then?" Fred asked.
Before Serena could answer, she felt the odd movement once more. Something told her that she would be stupid to follow it but her curiosity won.
"I— I'll just go to the lavatory downstairs." she said. They were just near the stairs and Serena ran to it to follow the sound.
She was already on the run when Lee shouted, "Oi! That's Moaning Myrtle's loo down there!"
Serena didn't bother and just ran downstairs. She gripped her wand tightly and looked around trying to feel the sound and movement but there was no more.
"Lumos." she caught her breath as she waved her lit wand around her. There was no one there. Then there was a different sound approaching her from behind. Faint footsteps echoed around the corridor and she stayed where she was as it came nearer.
At first she was about to flip in annoyance for seeing the twins again. But the red hair she saw was not Fred's nor George's. It was Ginny's.
"Ginny! What on Merlin's beard are you doing here in your jammies?!" she demanded but then stopped when she noticed that Ginny had that blank expression again.
"Ginny!" she ran to her and shook her awake.
The girl blinked and almost fell on her knees. "Oh my! Are you okay?!"
Serena helped her stand up as she blinked her eyes hard and held her head.
"What are you doing here? What are we doing here?" she asked.
"I think you're sleepwalking again?"
She blinked again and sighed. Her pale complexion turned even paler and her knees started to shake.
"Easy, we should get you to the hospital wing—"
"No, I just need to get back to the dorm." she smiled weakly, "I'm getting tired of these late night walks."
"But Madam Pomfrey must have something to prevent sleepwalking right?" Serena insisted in a worried tone.
Ginny shook her head and insisted on going straight to their dorm. Serena finally agreed and lead Ginny to the common room.
The other girls were already sleeping soundly when they entered their room. Ginny went straight to her bed and placed her diary inside its drawer.
"I didn't notice you have that the whole time." Serena spoke. She really didn't.
Ginny just shrugged and went to bed.
Serena stared at Ginny, who immediately fell asleep, then to the drawer beside her. She was resisting the urge to break it open and check the notebook out. Her bed was already prepared and she lied down but was still staring blankly above her. Her thoughts trailed from the sound and then to Ginny's sleepwalking issue.
'There's something suspicious about that diary,' she thought.
