When Rose first stepped into the forest, she could almost feel the happiness seep out of her. Although the Dementors were quite far in, she was so nervous she could hardly recall any happy thoughts. She glanced over at Scorpius and saw him staring straight ahead, ignoring everything around him. "Pretty exciting, hey?" Alice whispered to her, coming to walk beside her. Rose simply nodded, not trusting herself to talk. It was just like Alice to be excited about something so scary, but she'd most likely freeze up moments before we reached the Dementors.
During the hike through the forest, Rose tried to distract herself. She tried listening to Alice as she blabbered on, but she couldn't absorb what she was saying. She also tried naming the plants that she could see, but there few plants other than the enormous trees. Eventually, she gave up and just walked.
At one point, an ominous shape emerged from the shadows. The teachers all raised their wands at it, but the shape that came into view was a very mangled broomstick. It looked as though it had once been a school broomstick, but it was now almost beyond recognition. Many of the sticks from the tail were missing and the remaining ones were bent at odd angles. It only hovered a few metres above the ground and moved with sudden jerks. The broom flew by the group and disappeared back into the darkness of the forest. Rose saw Professor Longbottom whisper something to Horton, who chuckled.
The forest got considerably colder as they walked further in and soon they all had their wand tips glowing to light the way. After they'd been walking for what seemed like ages over massive tree roots, Horton stopped and shushed them all. "The Dementors are just up ahead." she said quietly to them all. "We're going to attack them from all sides and force them upwards, out the top of the trees. There's several Aurors and Ministry workers waiting above on broomsticks. They'll take care of the rest. You'll each have two teachers with you. right, I trust you know how to get yourselves into groups." Rose and Alice managed to end up in the same group. Unfortunately for Rose, Scorpius and Natalie was also with them.
Professor Longbottom and a teacher Rose didn't know led them to the right. Alice had fallen silent and was now looking very scared. They walked in a wide circle for a while, then Longbottom stopped them. "Ok everyone." he said to them. "We're on the opposite side to where we were before. Just spread out, but stay close enough together that we can help you." they waited for a moment in complete silence, then an owl hooted in the distance. "Alright, that's the signal. Let's go." the Professor , they moved forward in a tight knit circle. The air got colder and Rose struggled to hold on to her happy memories. They emerged from the trees into a large clearing. The sight made Rose gasp. What looked like almost a hundred Dementors were gliding around the clearing, some floating around the higher tree branches. The cold made Rose's teeth chatter and her skin was covered in goosebumps. "Now!" Professor Longbottom yelled. Rose snapped into action and raised her wand."EXPECTO PATRONUM!" she shouted. The phoenix burst from her wand and soared towards the Dementor. Around the forest she could see several other silvery shapes appearing and herding the Dementors to the centre, but they were too far away to clearly make out. Several trees away, Rose heard Alice yell the spell and saw the Labrador burst out from her wand and started bounding around the clearing. Looking around, she noticed Natalie standing at the very edge of the trees, her owl Patronus defending her from an approaching Dementor. Rose turned to look at the edge of the trees, looking for Scorpius, but he was nowhere to be seen. Professor Longbottom and the other teacher stood with Natalie, who was struggling to fend off a group of Dementors. Rose turned back to the clearing and saw her phoenix was flying higher up, forcing several Dementors above the canopy.
Suddenly, Rose felt an overwhelming sadness. All happiness vanished and she felt as cold as the lake during Winter. She looked ahead and saw several Dementors gliding towards her. She glanced up and saw her Phoenix had faded. She tried to scream, but it came out as a whimper. She backed up until her back came up against a tree trunk. The Dementors advanced and Rose held up her wand. "Expecto Patronum." she tried to yell. A feeble white mist came out of her wand and hovered for a few moments, but then faded. Dark spots danced in front her eyes, and the Dementors kept gliding forward. Rose tried screaming again, but no noise came out. Out of the corner of her eye, Rose saw another dark figure coming towards her. This was the end. There was no one coming to save her.
