why the heck was peter p.in gryffindor for??

not becouse he was brave. then why o why?

It might be that he really wanted to enter Gryffindor at the ceremony , just like Harry do .

Yeah. That's what I always thought.

hmm... not becouse he was brave no..

well it could be that his family was in gryffindor. they said it goes by families but Sirius was in gryffindor..so there is no proof there. so i have been lead to believe that he asked the hat. there is no other way

maybe he was once of noble heart, but he turned frantic from Voldemort.

I think that Peter was very brave when he was 11. He snuck around after hours with the marauders, broke rules, became an unregistered Animagus, fraternized with werewolves.

After a while tough he just became a coward and a lowlife. If he was sorted later in life than i doubt he would have mead it into Gryffindor

Well, there's the simple fact that the person you are at age eleven is not necessarily who you are 3 years later, 4 years later, 5 years later, etc. etc. etc.

He could have, as well, chosen to be in Gryffindor, which though touted by Dumbledore as an integral aspect of Sorting isn't necessarily a good thing.

But bravery in what sense of the word? What about daring? Daring born of fear may still be daring. It was daring to betray his best friend for a rising powerful darkness.
It was brave to attempt a human transfiguration in order to accompany a werewolf, sans Wolfsbane, on a full moon, despite whatever help he may have received.

And of course not each person is absolutely representative of their House.
