Hello, everyone!

Firstly, i'd like to say that i would be
disappointed if McAllister were RJ, because his charater changed a lot
since episode "Red hair and silver tape". I mean, i didn't even
recognized him this season, i thought that he was portraited by another
actor, not Xander Berkeley.

Ok, now, let's go to the main point:
se.05 ep. 22 - "Red John's Rules". When Lisbon is talking to Jane about
who was Aileen Turner/Leelee Barlow, Lisbon told Jane abou HER happy
memory, it was: Lisbon's mother feeding pigeons at the park,
related to the song "MacArthur Park" (a cake left out in the rain).
After that, in episode 06x02, "Red-winged black bird", there's that
scene with Lisbon and Jane at that park and a strange woman feeding pigeons.

So,
reading this song lyrics, it refers to a cake that take so long to bake
(it reminds me Sophie's head in the oven). But i can't find something
really interesting in this lyrics.
But (!!!!!!) the pigeons are
important references. Since Red John was in a house full of pigeons when
he "killed" Brett Partridge, how could RJ be Sheriff McAllister, if
he's afraid of birds?
