I've posted SEVERAL TIMES about SEASON ONE CLUES -- #8676 and #9096, because I think Heller's KNOWN FROM DAY ONE who RJ is -- and the CLUES are ALL buried in the beginning, like in ANY good story.  So, I will list them again because IT'S TOO BAD THAT SOME PEOPLE SAY the clues mean nothing.  As more of these clues are addressed, the more we will know about the whole story.

A TATTOO  [3 DOTS]
CLOWN       [I think this is the origin of the smiley face actually, which is likely a sad clown]
TWINS        [KIRKLAND]
CORRUPT LAW ENFORCEMENT [BLAKE ASSOCIATION]
The NAME THOMAS   [THOMAS MCALLISTER]
PSYCHICS
HYPNOSIS
FOOTBALL
REDHEADED WOMEN
A "WHALE" or GAMBLER  [GALE BERTRAM]
FARMS  [TANNER FARM/ELLISTON VISUALIZE BARN/KIRLAND BARN]
PINEAPPLE [GRACE LIKES/CHO HATES/Cop killed by Cordero orders "pineapple cheroot" before dying]
GOLF 
WATER/MARINA/BOAT

THINK this covers it -- but maybe I missed "BIRDS" and "SURVEILLANCE" LOL

SOME PROMINENT SEASON ONE PLOT THEMES I think might echo character's:  as Lisbon's story was told in #3 episode plot, and McAllister's hidden truth was shown in episode #9
A FATHER RAPING/KILLING DAUGHTER
A MAN KILLED BY HIS WIFE
SIBLING against SIBLING
An ILLEGITIMATE CHILD kept a secret
A MAN ACTING MUCH DUMBER THAN HE REALLY IS  [THOMAS MCALLISTER]
VERY ABUSIVE FATHER 
TROUBLED YOUTH 
WOMAN USING MEN TO KILL FOR HER


We shall see...
