One part I don't understand
When Rick drives up to Dr. Carlos house in the middle of the night and wants him to hypnotize him again so he can flashback to his brothers murder yet again, why did Dr. Carlos seem so intent on pulling a gun on Rick and possibly shooting him right there in the study?
I also noticed Dr. Carlos had the gun on him when he chases after Rick once he bolts out of the house, but Rick had already peeled out in his car.
So I guess my question is why did Dr. Carlos almost shoot Rick? Was he just scared or did I miss something?
