Then add in Rome's parents who were pretty much a mess and his brother who was always the screw up while Rome did all the "good stuff" and they kept giving his brother every inch they could. Then add in Regina's own mother was also abused at even though being in her 60s just can't face it and not only doesn't want to talk about it, but acts like it will be a GIANT SCANDLE if she even admits it outside of her own daughter and son-in-law. Then again, look at the mess that was John, NO ONE KNEW about his life before they call met him. Suffering from 9/11 survivors guilt. His kids were named after people he argued with at the terminal who didn't let him "die on the plane." Some asshole firefighter who was like: "Oh I know you feel guilty about your friend's son never knowing his father, because you didn't die with him, but give us $74K FUCK YOU!" "Plus, let's just let him think I'M HIS FATHER because you know, it will be too hard to know his real dad died on the planes!" Um... how many other kids who weren't born yet lost parents in 9/11. The writing on this show is horrible and the characters not only don't communicate, but live in their own fictional world.
Now, we got the father who runs over the guy he "thinks killed his daughter" because said sister came out of the woodwork and one call where the girl's sister told him blankly on the phone: "My parents are doing really, really bad, especially dad, this will kill them." Yet he magically can stalk said person outside a bar and then hit him at 5 mph to paralyze him and then goes: "oh shit, I better call 911." Huh?
