Did anyone notice this fact ?
*When Teresa Lisbon came near the house the house blasted.
So it appears that Red John didn't want Teresa to get hurt so he blasted the house before she went in there.

*When all the others are inside the house no one would know who is approaching or what is going on outside the house.Conclusion : who ever made this bomb blast was outside and was watching whats going on.

*Then , facts from various interviews from "The Mentalist" crew reviled that it was RJ who made the blast.
So think about it. RJ is not someone who was inside the house when the BLAST occured.

*I still believe that Partridge is alive and his death was fake.And after considering all the facts available i still believe "Partridge" is Red John.
