Ok, so why did the Qassimi brothers feared Ridley? I mean he wasn't the supervillain that we expected from how they reacted to being arrested. "You just killed us" was what they said if I remember correctly. The way Ridley treated Jane was suspicious, "you would understand". Also, how did they manage to get that necklace into the prison? Lisbon wanted to pull the footage and then they left it at that. And why bring "tattoos" back now? "veni vidi vici", a three-part tattoo. I believe that the Blake association are in play and we might get to see them next episode.
