only a few hours left until episode 7 airs!
I've found a few more hints right here:

these are the ones I haven't seen before:
Despite being in an explosion and in the hospital, Jane's hair never looks less than amazing.
Someone utters the dialogue warning, "This is going to hurt."
If you need a reminder where "Tyger, Tyger" comes from, you'll get one.
Some key fixtures of the show do not survive the episode.
A big change happens in the final scene that will make things more difficult for our team moving forward.
Bonus info about post-RJ mentalist : Emily Swallow was cast as a series regular and will appear in episode 9 for the first time.
Cheers :)
