We caught glimpses of a future Toby holed up in bed and exhibiting signs of depression. We already know that Toby has a history of depression, since his parents mention that he had spiraled out of control after his first marriage ended. While it's easy to assume he's going through another bout of depression, what's not clear is why. Perhaps he's upset because the couple can't have kids, but maybe he's upset because he finds out that he's the cause.
