.You.do.know.why.we.are.here,.don.t.you,.Potter?..said.Snape,.in.a.low,
.dangerous.voice...You.do.know.why.I.am.giving.up.my.evenings.to.this.tedious.job?..
.Yes,..said.Harry.stiffly..
.Remind.me.why.we.are.here,.Potter...
.So.I.can.learn.Occlumency,..said.Harry,.now.glaring.at.a.dead.eel..
.Correct,.Potter..And.dim.though.you.may.be.‐..Harry.looked.back.at.Snape,
.hating.him..‐.I.would.have.thought.that.after.over.two.months.of.lessons.you.might.have.made.some.progress..How.many.other.dreams.about.the.Dark.Lord.have.you.had?..
.Just.that.one,..lied.Harry..
.Perhaps,..said.Snape,.his.dark,.cold.eyes.narrowing.slightly,..perhaps.you.actually.enjoy.having.these.visions.and.dreams,.Potter..Maybe.they.make.you.feel.special.‐.important?..
.No,.they.don.t,..said.Harry,.his.jaw.set.and.his.fingers.clenched.tightly.around.the.handle.of.his.wand..
That.is.just.as.well,.Potter,..said.Snape.coldly,..because.you.are.neither.special.nor.important,.and.it.is.not.up.to.you.to.find.out.what.the.Dark.Lord.is.saying.to.his.Death.Eaters...
.No.‐.that.s.your.job,.isn.t.it?..Harry.shot.at.him..
He.had.not.meant.to.say.it;.it.had.burst.out.of.him.in.temper..For.a.long.moment.they.stared.at.each.other,.Harry.convinced.he.had.gone.too.far..But.there.was.a.curious,.almost.satisfied.expression.on.Snape.s.face.when.he.answered..
.Yes,.Potter,..he.said,.his.eyes.glinting..That.is.my.job..Now,.if.you.are.ready,.we.will.start.again...
He.raised.his.wand:..One.—.two.‐.three.‐.Legilimensl.
A.hundred.Dementors.were.swooping.towards.Harry.across.the.lake.in.the.grounds….he.screwed.up.his.face.in.concentration….they.were.coming.closer…
.he.could.see.the.dark.holes.beneath.their.hoods….yet.he.could.also.see.Snape.standing.in.front.of.him,.his.eyes.fixed.on.Harry.s.face,.muttering.under.his.breath….and.somehow,.Snape.was.growing.clearer,.and.the.Dementors.were.growing.fainter….
Harry.raised.his.own.wand..
.Protego!.
Snape.staggered.‐.his.wand.flew.upwards,.away.from.Harry.‐and.suddenly.Harry.s.mind.was.teeming.with.memories.that.were.not.his:.a.hook‐nosed.man.was.shouting.at.a.cowering.woman,.while.a.small.dark‐haired.boy.cried.in.a.corner….a.greasy‐haired.teenager.sat.alone.in.a.dark.bedroom,.pointing.his.wand.at.the.ceiling,.shooting.down.flies….a.girl.was.laughing.as.a.scrawny.boy.tried.to.mount.a.bucking.broomstick.‐.
.ENOUGH!..
Harry.felt.as.though.he.had.been.pushed.hard.in.the.chest;.he.staggered.several.steps.backwards,.hit.some.of.the.shelves.covering.Snape.s.walls.and.heard.something.crack..Snape.was.shaking.slightly,.and.was.very.white.in.the.face..
The.back.of.Harry.s.robes.was.damp..One.of.the.jars.behind.him.had.broken.when.he.fell.against.it;.the.pickled.slimy.thing.within.was.swirling.in.its.draining.potion..
.Reparo,..hissed.Snape,.and.the.jar.sealed.itself.at.once...Well,.Potter….that.was.certainly.an.improvement…..Panting.slightly,.Snape.straightened.the.Pensieve.in.which.he.had.again.stored.some.of.his.thoughts.before.starting.the.lesson,.almost.as.though.he.was.checking.they.were.still.there...I.don.t.remember.telling.you.to.use.a.Shield.Charm….but.there.is.no.doubt.that.it.was.effective…..
