Season 6 episode 1 
Ok so at then end of that episode partridge is supposedly killed by Red John (McAllister). When lisbon  entered the room she was attacked by pigeons, as we all know McAllister is afraid of pigeons. Everyone is saying that the way partridge died isn't rj like. I have to agree with them on that but i was thinking maybe mcallister rushed it because there were pigeons in the room, he was scared and was sloppy. He heard Lisbon entering the house and couldnt finish what he started. Maybe thats the reason why maybe not, who knows partridge could still be alive. But if McAllister is red john, that is my opinion on what happened that night.
