That episode had only 1 redjohn clue from what I saw :( I was really disappointed!! The episode itself was amaazing though!!! Patrick saying to Reede Smith, "Everybody makes mistakes." i hope they find Michael Kirkland alive, it wud be nice.
O well, this theory made like a fewdays ago tells who redjohn really is and outlines who is in tiger tiger even before this episode with kirkland airs. its a really interesting read so i share a link with you guys. Happy mentalising!
