.It.s.only.my.ankle,.I.can.do.it.myself!..said.Ginny.impatiently,.but.next.moment.she.had.collapsed.sideways.and.grabbed.Luna.for.support..Harry.pulled.Ron.s.arm.over.his.shoulder.just.as,.so.many.months.ago,.he.had.pulled.Dudley.s..He.looked.around:.they.had.a.one.in.twelve.chance.of.getting.the.exit.right.first.time.‐.
He.heaved.Ron.towards.a.door;.they.were.within.a.few.feet.of.it.when.another.door.across.the.hall.burst.open.and.three.Death.Eaters.sped.in,.led.by.Bellatrix.Lestrange..
.There.they.are!..she.shrieked..
Stunning.Spells.shot.across.the.room:.Harry.smashed.his.way.through.the.door.ahead,.flung.Ron.unceremoniously.from.him.and.ducked.back.to.help.Neville.in.with.Hermione:.they.were.all.over.the.threshold.just.in.time.to.slam.the.door.against.Bellatrix..
.Colloportus!..shouted.Harry,.and.he.heard.three.bodies.slam.into.the.door.on.the.other.side..
.It.doesn.t.matter!..said.a.man.s.voice..There.are.other.ways.in.‐.WE.VE.GOT.THEM,.THEY.RE.HERE!..
Harry.span.around;.they.were.back.in.the.Brain.Room.and,.sure.enough,.there.were.doors.all.around.the.walls..He.could.hear.footsteps.in.the.hall.behind.them.as.more.Death.Eaters.came.running.to.join.the.first..
.Luna.‐.Neville.‐.help.me!..
The.three.of.them.tore.around.the.room,.sealing.the.doors.as.they.went;.Harry.crashed.into.a.table.and.rolled.over.the.top.of.it.in.his.haste.to.reach.the.next.door:.
.Colloportus!.
There.were.footsteps.running.along.behind.the.doors,.every.now.and.then.another.heavy.body.would.launch.itself.against.one,.so.it.creaked.and.shuddered;.Luna.and.Neville.were.bewitching.the.doors.along.the.opposite.wall.‐.then,.as.Harry.reached.the.very.top.of.the.room,.he.heard.Luna.cry:.
.Collo—.aaaaaaaaargh…..
He.turned.in.time.to.see.her.flying.through.the.air;.five.Death.Eaters.were.surging.into.the.room.through.the.door.she.had.not.reached.in.time;.Luna.hit.a.desk,.slid.over.its.surface.and.on.to.the.floor.on.the.other.side.where.she.lay.sprawled,.as.still.as.Hermione..
.Get.Potter!..shrieked.Bellatrix,.and.she.ran.at.him;.he.dodged.her.and.sprinted.back.up.the.room;.he.was.safe.as.long.as.they.thought.they.might.hit.the.prophecy.‐.
.Hey!..said.Ron,.who.had.staggered.to.his.feet.and.was.now.tottering.drunkenly.towards.Harry,.giggling...Hey.Harry,.there.are.brains.in.here,.ha.ha.ha,.isn.t.that.weird,.Harry?..

.Honest,.Harry,.they.re.brains.‐.look.‐.Accio.brain!..
The.scene.seemed.momentarily.frozen..Harry,.Ginny.and.Neville.and.each.of.the.Death.Eaters.turned.in.spite.of.themselves.to.watch.the.top.of.the.tank.as.a.brain.burst.fro.the.green.liquid.like.a.leaping.fish:.for.a.moment.it.seemed.suspended.in.midair,.then.it.soared.towards.Ron,.spinning.as.it.came,.and.what.looked.like.ribbons.of.moving.images.flew.from.it,.unravelling.like.rolls.of.film‐.
