Kara tinsley from season 6 is another huge clue*****
Besides the fact she saw a tattoo on the person who FAiLEd at killing her and let her speak to patrick!
She never said she was sent by visualize .
Cho gave her that option and she just agreed.
She WORKED FOR RED JOHN AND HER JOB WAS TOO LEAD PATRICK TO THR BLAKE ASSOCIATION!!
Otherwise her killer would of KILLED her. Without leaving her time to talk.

Also , rigsby told cho he was gonna get him a girl and lo and behold a girl hired by red john comes to cho ;) hmm
