He chuckled. "You're too bright sometimes. You think too big. Remember, it was
all of those small charms in your earlier years that kept you alive when roaming the castle
on Harry's heels."
"Please," she said with a roll of her eyes. "It's more like chasing after his heels. That
boy can't help but run into danger."
"All the better that you're always there looking out for him," Remus said and quietly
added, "For everyone."
Hermione smiled appreciatively up at him. "To be fair, Harry has looked out for me
from time to time. Granted, he does tend to get me into a bit of trouble as well." Her gaze
turned forward, and she took a breath. "Here we are."
"Which door is it?" he asked. "I can't remember, myself. When we arrived to rescue
you all, it was a bit of a mess, and most of the doors were already open with people rushing
about in here."
"I can't recall specifically. I suppose we'll just have to investigate." She sighed lightly,
approaching a door. Upon opening it, she peeked in without stepping foot inside and
blinked a few times. "Huh," she muttered. "What does that look like to you?"
Remus glanced within and cast a Wand-Lighting Charm, which had no effect on
the darkness of the room. When he squinted, he could see lights glimmering above them.
"The sky, I suppose."
"Space Room," Hermione said and promptly shut the door. "Not going in there.
They have a variation of a Limbo Mist Charm on the ground. Harry faced something
similar in the Triwizard Tournament. Ron, Ginny, and Luna got caught in here last time,"
she said, marking the door with a large circle to differentiate from the exit, and immediately
immobilised it per his example.
Remus turned to the next door and opened it. The sight within caused his eyes to
widen.
"Oh!" Hermione exclaimed, stepping inside. "Be careful, I've seen first-hand what
Time-Turners are capable of."
"You have no idea," Remus murmured, his heart racing as he stepped into the room,
scanning every detail.
Hermione's sudden smile carried a surprised nostalgia. "I can't believe they were
able to put it all back together."
