I was planning on re-watching season 5 so I'd remember what was going on but I ran out of time. I know in the last episode, Julia had found out that Eden (the gf's daughter) was poisoning her and she ended up in the hospital because of a gunshot wound. They claim that she has amnesia and doesn't remember anything before the shooting. I can't remember who shot her!
I wander though if she really has amnesia or if she's just pretending to not remember anything so the girlfriend and Eden let their guards down.
Also, Shawn was stabbed by the psychotic agent while he was operating on a little girl. When the episode ended, he was lying on the floor bleeding pretty bad.
