A control box in 'OS' has a logo for "Gray Electric" with a lightning bolt symbol. This foreshadows the main suspect in 'Stowaway', Dana Gray, who had been struck by lightning multiple times.
A folding fan seen in the background in 'Stowaway' foreshadows Fauxlivia giving birth in a Chinatown gift shop in 'Bloodline' that has folding fans hanging from the ceiling.

CASE REPORT SUMMARY:Dana Gray was murdered eighteen months ago by two bullets to the head. The medical examiner said she died instantly, along with her husband and her children, in a home invasion robbery. Two agents killed the robber in a shoot-out, and the case was closed. However, Gray's body disappeared from the morgue. Not long after, witnesses reported seeing two people jump out of a dorm window. Police officers arrived and found there was just the body of the student. The officers found two sets of fingerprints on the ledge, one set identified as Dana Gray's. Over the next two months, her prints were found at three other double suicides. Security photos and eyewitnesses showed her there. It was hypothesized that she couldn't die.
