The episode of DTF St. Louis revealed that Clark (Jason Bateman) had helped Floyd (David Harbour) sign up for life insurance amid financial concerns and concerns about his health. While Carol (Linda Cardellini) was aware that Clark was helping Floyd get in shape for his insurance physical and was aiming to sign up with a policy, she preferred to be kept out of the details. The episode revealed that the mystery key Floyd had on his person in death was tied to a P.O. Box where his insurance paperwork was sent to. The question remains whether Carol knew about her affair with Clark or if Floyd would have named Carol his beneficiary if he'd known about it.
