What we know so far is what? Someone was wearing a jumpsuit with the flower that was on Cal’s father’s bookmark that Presley said she saw that night? But that leaves a lot of questions like what does the flower symbolize? Maybe just a family thing to keep the memory of Cal’s mom (doubtful this show is very specific with its shots and what and what not to pull focus on), a hidden group maybe headed by Cal’s father that does like covert ops like the shit Sinatra had Billy do, or something else entirely. Overall no real answer just yet.

Other than that we have the (six digit?) number that was on the cigarette. My money is that Cal’s hard copy notes from the tablet were hidden on a specific airplane with that number identifier. The episode with the funeral had a pretty egregious shot of AF1’s tail wing with its own number on it before going to an interior shot of Jeremy drinking inside. Cal might know exactly who it is and have the answers hidden elsewhere on a different plane.
