Pettigrew parallels

[Sister Mary Lunatic]

No: HPFGUIDX 5350

Everyone seems to picture Peter Pettigrew as just a tag-along to the
Marauders and not part of a foursome.  But you're overlooking the fact that
he learned, with them, the extremely difficult Animagus magic, which means
he must have been a regular member of the group.  Not only that, but his
name is also on the Marauders Map as one of the "manufacturers" --
suggesting again that he was closely involved in the day-to-day shenanigans
of the group.  James and Lily considered him an acceptable substitute Secret
Keeper when Sirius suggested it (and of course, Sirius trusted him
completely at this point as well, which indicates he was not a casual or
annoying acquaintance).

Perhaps there are no intended parallels between the generations.  Harry,
Ron, and Hermione are coming from a totally different place than MWPP.  In a
way, Hermione might parallel Lily, if we knew for sure that she was a
long-term important member of the group (but then why isn't HER name
included on the map, and DID SHE BECOME AN ANIMAGUS TOO?)  Or was she just
James' girlfriend and not included in their rule-breaking exploits.  Did
Lily have any close friends?  I haven't seen anyone come up to Harry and say
"I knew your Mother well, she was one of my best friends, blah blah blah".
