I was finally able to get back on my moms pc after watching the latest episode.

We now know that red john did infact visit sophie miller, infact it seems he left jane some leftover dinner in the oven as well. (Quite nice of him if you ask me)

If you remember couple seasons back, we found out that sophie was janes psychiatrist after his breakdown following the murder of his wife and daughter.
As most people theorised she was the link with how red john was able to kill a happy memory of janes.

We also learnt a couple more details about red john though as usual they are rather vague and broad.

He has a fear of Acrophobia or some other type of unknown phobia.
He is middle age.
He has no living family but many friends he relies on.
He is a a excellent whistler.
He is a damage and narcissistic individual.
He doesnt deal with conflict and adversity easily.
He speaks rather convincly when lying outright.

We were given glimpses of other red john suspects while the details of red shown were being told, implying that each of these individuals had atleast something in common with red john.

Its a good chance that in future episodes we will have more people whistling, on this episode alone we had reede smith, ray haffner and tom mcallister whistling.
Sadly though patridge didnt get a chance to belt out a tune as he was in a body bag.
