if its true rigsby and GVP wont be around for long, i think rigsby will be killed by someone from tyger tyger for looking into kirklands death.
GVP will be devasted and RJ will use the opportunity to use her as a tool against TT without revealing himself to her (Heller giving everyone their wish that GVP is somehow bad). GVP would help RJ since TT killed her husband although shes unwilling to work for RJ. She somehows figure one important clue which will determine RJ though and she proceeds to tell PJ everything, leading RJ to kill her. PJ finally figures who is RJ though with GVP's info, and still get to know about TT. However, TT also figures out who RJ is and kills him before PJ gets to him. This causes PJ to not get his revenge and since TT is a bad organization, PJ decides to bring them down. This serves as a story continuation after RJ dies.
Damn, i should be the writer for the show instead of Heller.
