Its implied that he really didn’t know because he was always somewhere goofing off or being overly indulged by the father
He didn’t know anything… they literally said in the story that they didn’t hang out together w lot as children. He was the only kind family member Ruby ever had
dude, he seriously didn't know, he seemed to have a falling out with Cesare, that's why he's been goofing off and not at home much, also Ruby didn't tell him anything, he was genuinely the only family Ruby had in Romania who honestly treated her like family
No he knew something was up, he just decided to ignore it.
I really wonder why y’all love Enzo so much tho ? He cute but he also knew Ruby suffered and he didn’t lift a finger.
