i think that grace van pelt knows who RJ is, and feeding him information about PJ.

how did RJ knew where PJ was going when he saved him from the copycats?, his phone was wire ,,, bugged. (van pelt)
how did RJ knew about Bertram and PJ's meating in the mall with Hightower (via van pelt).

the whole thing about the three dot org is orchsterated by PJ to catch RJ.
like in other episode when he points out a wrong victim to catch the real one like the panzer case. but this time its on a biger scale.
and PJ doesn't trust his team,,  he knows there is a mole but not who.

PJ witnessed the killing of the copy cats and when RJ's gone he had a small smile, he knew something more about RJ,,, to lure us, there was the tyger poem, but PJ knew more, one essential thing that RJ dosen't like imitations of his work, and this is the only way to bring him somewhere.
RJ have the TIGER TIGER org.
PJ have the three dot org,, but only Bertram and kirkland know about PJ
Reede and macallister are following Bertram and kirkland, and for them the three dot org is to catch RJ because PJ is not doing the job. and to find out about tygers. That's why reede aksed betram; how much does PJ knows about all this.

PJ did have a discussion with kirkland after his arrest,, we didn't see it and neither his team mates. and we will later know what was it about.
Kirkland was supposedly shot in a prisoner's clothes. but he was arrested in a costume  he had all the time to be arrested and then to be transferred. that's when PJ talked to him.

Smith shot kirkland in front of a tiger tiger. it was a lure
partrige and kirkland are not dead,, The PI kira if dead she was a sacrifice (as in chess, PJ is a good chess player). all those fake deaths were cheap imitations of RJ's work.
throught his mole in PJ's team RJ know that somebody is imitating him (the Partridge killing)
and also knew throught the same mole that the same killer tried to bugg PJ's team and killed the PI, and this guy has a three dot tatoo. so now RJ is looking for this killer.
and since whe PJ tell his team mates about his projects,, but this time he told them his going to bring all five remaining suspects and sees witch one has the three dots tatoo, knowing that RJ would want to kill his imitator. and most probably RJ will be after reede Smith,, because the tyger tyger report that kirkland was killed by him and since reede is not a tiger he could only be the false imitator.

why cho misguided the PI KIRA, into accusing visualise, is he involved?
