Here are the facts: - The pilot of the Oceanic 815, Seth Norris, was killed by th smoke monster. ("Pilot part 1") - Frank Lapidus was supposed to fly the plane on the day of the crash. ("Confirmed Dead") - Frank Lapidus finally arrived at the island, first with the Kahana, as the chopper pilot ("Confirmed Dead"), then he managed to leave with the Oceanic-Six and Desmode, then he came back as the pilot of the Ajira 316. ("316") - Ilana and Bram suggest that Lapidus may be a "candidate" - for what? ("The Incident") - Perhaps Lapidus' role on the island will prove to be significant, considering that he ends up there twice.
So... what if the smoke monster was looking for Lapidus in the first place?
