Headscratchers / The Righteous Gemstones

• In "Interlude II", why is Roy unsupervised? He lives in a house all alone despite clearly being senile. No nurse or caregiver are seen or mentioned either time when he’s running around with a shotgun. It’s not like Eli is too stingy or neglectful of his father to hire some 24-hour care. Who’s keeping an eye on him?
• In "They Are Weak, But He Is Strong" a funeral program shows Aimee-Leigh's birth year as 1955. In "Interlude 1," Baby Billy objects to her pregnancy, saying she's "well into her 40s," however, she'd only be in her mid-30s in 1989 (though that was still considered a later than average age to have a baby at the time.) Could be a case of Writers Cannot Do Math or simply a case of Baby Billy being so It's All About Me he doesn't even know how old his sister is.
