red herrings mean like....errr....sort of misdirecting somebody into thinking something wrong/opposite...so j.k can surprise us...u know get us to think of something but then tada! it's different! so we keep on getting surprised...?sorry i'm not very good at defining things...

lunatic means crazy about the moon....i'm not joking actually, see befor they used to think if u stare at the moon u become crazy hence lunatic! ask ur english teacher if u don't believe me!! so maybe luna is gonna do something to make lupin a LUNA-TIC? especially since he is a werewolf?

i'm sure the following is no new news that dumbledore's bro is gonna turn up in the story either 6 or seven. u'know aberforth? right why, u ask? because in the first book she said hagrid borrowed the motor bike from hagrid....boom, a few books later he is one of the main charecters. she has mentioned aberforth two times, so he is due. he is strange and did something illegal to a goat, and in book 5, the ministry of magic has a department for illegal mixing or breeding whatever of animals(check book 5, when mr weasly talks to a strange guy holding a box). and i read that in greek mythology there is a creature part goat, part lion and part snake...maybe? no? anyways...aberforth is due to showup and i read somewhere a theory saying he is the guy at hogshead harry thought "looked familier"...
oh and i think collin creavy is gonna backstab harry and/or his friends like wormtail did. neville is NOT like wormtail he is loyal and brave...he doesn't follow ron,harry,hermy around...however collin does follow harry around and he certainly looks the part...very mousy indeed.
sorry i wrote alot.
