Elon Musk Concerned About Father's Relationship With Former Stepdaughter

Elon Musk worried his father Errol was inappropriately attentive to 15-year-old stepdaughter Jana.

Errol later had 2 children with Jana when she was in her 30s.

Elon was upset and tried to get Errol to change his behavior.

Errol moved back to South Africa, divorced Jana's mom, then moved in with Jana.

Elon cut off his dad financially after learning about the pregnancies.
