As far as I am aware, Dijana’s brother didn’t commit suicide, he died. My impression was that he had died in a car crash, but I actually don’t know.
I was trying to illustrate that dijana has experienced the loss of a loved one and knows that pain and is therefore vulnerable when someone threatens suicide. I apologise for any confusion
No worries, the significant part is that she lost someone close suddenly and unexpectedly. No one wants to go through that again so using it as any kind of coercive threat is low.
I am not a doctor, but I don't think Lloyd is suicidal in the slightest. I don't think he's bothered at all by how he hurts other people, if he did he wouldn't do it so frequently. I think he uses the "mental illness" card as a punchline to escape criticism and take the heat off himself.
A sociopathic narcissist doesn't seem like the type who would be wracked with guilt to ever "off" themselves. He seems as far away from having empathy for another person as I can imagine.
