A Destroying Seeker
Before they could make it out though, Bella had already made a seeker from her wand.
Bella: Seek out the owl… and destroy him!
Instead of the fireball being green, this one was red and started seeking out Harry. Harry and Luna flew out of the cave with Draco trying to block it with his body but the fireball moved in a different direction. It started flying out of the cave and started chasing Harry and Luna. Draco landed roughly on his back and Bella started laughing evilly. Behind Draco, Astoria then started telling him what to do.
Draco: No! Harry!
Astoria: Break the wand. Break the wand. Look, the fireball will die if you break the wand!
Draco then took his sword, got up and lunged at Bella. But Bella had started shooting at him, so Draco moved out of the way. While that was going on, Harry and Luna had kept on avoiding the fireball. They then saw Hermione by the river and pointed towards it.
Hermione: Harry!
They dove in the water and began swimming underwater for a few seconds until they couldn't breathe anymore. They got out and flew away with the fireball right on their tails. Back at the cave, Draco was having trouble avoiding the beams until he got struck by one. With Draco down, Astoria then started telling Draco to get up, silently.
Astoria: Come on! Get up!
Bella: Bye Draco.
But before she could finish him off, Bella was shocked to hear Voldemort's voice. But it really was Astoria, laying on a ledge, using Voldemort's voice. With Bella looking around for Voldemort, Draco finally caught his breath and got up. Astoria was doing a good job of distracting Bella until she saw her and started yelling. That made Astoria get up very fast and panicked.
As Voldemort: Hello, Bella.
Bella: Voldemort, you're alive?
As Voldemort: Amazing, isn't it? Thank you for recovering the Forbidden Arts. But now you're through. Tell you what though, I'll give you a chance to run.
Bella: Traitor.
Draco: Bella.
Draco had managed to grab the wand and they began fighting over it. Back outside, Harry and Luna began flying through some vines until Harry got tangled in some of them. Luna came back to him and was trying to untie Harry before the fireball could get closer.
Harry: Luna.
Back in the cave, Draco and Bella were still fighting over the wand until it finally broke. Once it broke, it made Bella fall onto the trap which destroyed her. It made a blinding light which made Draco, Astoria and Pansy cover their eyes so they wouldn't go blind. Once the light had cleared, Draco began running to the entrance, hoping to see Harry along with Astoria and Pansy following him.
Draco: Harry. Harry?
He then saw Luna flying towards them with Hermione running with her. Draco was shocked to see that Harry wasn't with Luna so he started asking her which made Luna upset.
Draco: Where is he? Where's Harry?
Luna: Oh, Draco. He's gone.
Draco: Gone? What do mean, gone?
Luna: The fireball. He couldn't get away.
Draco: No. No. No!
He then started slashing some rocks into pieces until his sword broke and the others had their heads down sadly.
Draco: Harry. Harry.
He then began sobbing uncontrollably while the others were still moping also, upset that Harry was gone.
