Some people have been saying how did Red John make the call to Lisbon's phone as he was using 2 hands well when Red John rings Lisbon's phone it takes a couple of seconds for Jane to anwser it now he talks to Red John for roughly 7 seconds befor we first get a glimpse of Red John at the house and then it takes him about 10 seconds to draw just the mouth of the RJ smiley face so if we say it took him 10 seconds to draw the eyes and 10 seconds for the face part then he would have been drawing the face for about 30 seconds so a couple seconds to make the call then couple seconds for Jane to anwser it and 17 seconds roughly untill Red John hangs up means he would have been srawing the face about 13 seconds befor he made the call so to me this is  clear evidence that There were 2 people at the house that night mayby RJ and a helper as RJ woulodnt have been abble to make the call as he would have blood on his gloves :)

tell me what you think cheers :)
