From Harry's Point of View.
One minute, I was confidently bragging on Lily's ability to handle Boggarts, and how she would take this one down with ease.
The next, Voldemort was in the room with us and pointing his wand directly at her with his long, spidery fingers.
Then there was panic.
Sheer panic.
Some were screaming and running in different directions, trying to escape as quickly as possible.
"It's him!"
"He's gotten into the castle, and disguised himself as a Boggart!"
Others were trying to calm them down, explain to them that it wasn't actually Lord Voldemort, just a Boggart transformed as him, though they were frightened as well.
The rest of the students were trying to back away as quickly as possible and tripping over others in their effort.
Lily stood, frozen, looking up into the eyes of Voldemort, that more resembled red slits.
The pale Boggart Voldemort hissed at her. "I will kill you.." he whispered. "Just like I killed them." he said menacingly in his high-pitched voice.
Her eyes were wide, her lips slightly parted, almost as if she was about to say something.
Her expression did not show horror, or even fright, only..recognition.
Then the moment was shattered, and she was on her knees shrieking as if she had been hit with the Crucius curse.
I quickly pointed my wand at the Boggart, and shouted "Riddikulus!" It changed back into it's original cloaked form and fell back into the chest.
Lily lay on the floor sobbing uncontrollably.
Seeing that 'Voldemort' had disappeared, the students slowly gathered around her.
"Did he kill her?"
"Did you hear what he said to her?"
"He used the Cruciatus curse on her, I swear!"
I pushed my way through the small crowd that had formed, and knelt down beside her.
I looked up to find Ron and Hermione standing near me.
"Ron, Hermione, get everybody out of here and into their Dormitories. Now." I ordered.
They both nodded and started herding people out the door. It didn't take much effort, considering everyone was ready to get out of there.
I put put my arms around Lily. "Shh, it's okay, now. He's gone. It was just an illusion. He won't hurt you."
Seeing that my words weren't helping, I gently picked her up. "Let's get you out of here."
I carried her out of the Room of Requirement upstairs to the Gryffindor Common Room, which was mercifully empty.
By then, her sobs had subsided somewhat. I sat down with her in front of the lit fireplace, and just held her.
A few minutes later, she pulled away, wiped the tears off her face, and blankly stared into the fire, completely silent.
Then she turned to me, her gray-blue eyes staring into mine.
"Looks like we have something in common, Harry." she whispered sadly. "Something I didn't want to tell you."
She looked back towards the fire. I looked at her questioningly, and waited for her to explain.
"Voldemort murdered my parents too."
