So no way the concussion bomb didnt knock out macaluster too right ?
Macilister was knocked out like everyone else . Red john and his helper i assume dragged all the bodys out and red john being an arson specialist (rigsby) set the real bomb off.

I have a feeling styles knows so much about red john because rj was or is in visualize.
Red john let styles who may be his father , and haffner , possibly his brother lol go.
Before styles left he hypnotized macalister .
This would explain macalister seeming weird and having those googly eyes from the church scene .
Also the pigeon may have had a bigger affect from him being in a trance.
Styles haffner rigsby van pelt are all on my watch list.
Re watch this season and look at everything rigsby said and does
Also go back and watch the episode where kristins frye is taken
Listen to rigsbys response when lisbon was explaining to him how they were handling kristinas watch.
Then think about how she was taken and who coulda pulled it off since she left on her own and was "lured" out. Possibly a trusting face led her???
