I have a strong guess that lisbon is an accomplice to red john , and jane knew it all the time , and he uses her to mislead Rj , especially when it comes to the suspects list, Sometimes when Teresa asks him  a question , U see his eyes like shining , like it's clear that he's lying to mislead Rj , so wheather Teresa is an accomplice to Rj or Rj have someway to pull informations from her
