Last episode Rigsby says to Cho "I'll find you a girl" and next thing you know that private detective is flirting with him and bugging his office. Season 1 episode 22 about 27 minutes in Rigsby seems to have 3 dots on his left shoulder. Is it a tattoo or just dirt? The person who strangled the private detective last episode had a long sleeve shirt on so she wasn't describing her killer but Red John.  Also, the actor playing Rigsby is leaving the show half way through the season. Also, in the pilot Partridge says the name Red John and runs into Rigsby at the same time. I'm sure Bruno knew who Red John was in the pilot so it has to be someone in the pilot. Also, if it's not one of the main characters we know and love...boring!
