If red john did not kill lisbon when he captured her then there has to be a reason for doing so. Red john would kill anyone that is somewhat close to patrick jane. So for not doing so to Lisbon makes me think does he have anything towards her? Season 5 episode 13. Ray haffner talking to Lisbon and wanting her to move out of her current job where he is located and shows hints of him kind of jealous of how she wanted to stay with Jane. I feel like he likes her and for that reason he didn't kill her, therefore red john is Ray. I Hope this makes sense..
