I accept that and certainly not trying to 'shield him'. I like to think I have some understanding of human development and psychological processes that we all go through in response to positive and negative events (we'll id better, it's my job! Hehe)
I already made a decision to not expose him to a beloved characters death at this time. We will go down that track later when he's ready.
I was really just after info on season 3 onwards suitability and references to said death. Thanks guys for the info helps me to steer clear of any eps not so great for him at his young age
