I agree tbh, they didn't give two shits about Cain TILL he was starting to get over protected of his sister. you know there bad when the legit king and queen who couldn't see their kid due to their job knew more about their son then Cains parents knew about him. it is legit no wonder they BOTH became villains!! Cain became an asshole to his sister due to their parents giving her more love than they ever gave Cain in his whole childhood and had to grow up early and Diana became selfish due to their parents who compared her and her brother bringing down her self-esteem and always letting her have her way in life causing her to become spoiled!! it is legit the parents fault that ANY of the bad ends happened!! it is legit the parents fault that Diana pretty much died in all the timelines!! fuck them no SCREW THEM!!
Cain sure is a bit of a siscon but I not in an "incest" way. He wouldn't have had to educate Di if parents did their fucking job. He basically raised her because shit parents didn't do anything to raise either of their children. On top of they they almost forced Diana to study even harder by comparing her to Cain. They should've acknowledged and taken action if Cain looked "creepy/siscon" early on instead of pretending to care about it now since he has always been this way... Bet they're the type to boost about their genius son as if they raised him like that lol
