Cmon people, Lisbon said Haffner, Stiles and McAllisters bodies were found burnt and that DNA matches that.
One thing that I found curious was that in the Extended Promo for the next episode there is a pigeon (partridge) on the statues hand. I hate the theories that Partridge is Red John but isn't that strange? Plus all the pigeon's appearances on the first 3 episodes of this Season.
Also what was the shot before the explosion? And how can the 3 be dead if McAllister was alongside Bertram and Smith and they have no injuries whatsoever from the explosion?
Finally in the extended promo we see a bald guy with little grey hair running through glass and everything, as McAllister is dead and Bertram is on the run I'm sure it's Bertram. One of the most important skills in Mentalism is cold reading and a very special scientist named a study and effect after his own name: The Bertram effect (a.k.a. Forer effect.)
