I have been thinking about this today and in the Pilots there were clues which could lead us to think about Jacob.
- Jack Shephard - count to five on a 16 year-old girl (The Incident, Part 2)
- Hurley - talking about the dead pilot (The Incident, Part 2)
- Kate - Stealing (The Incident, Part 1)
- Jin and Sun's relationship (The Incident, Part 1)
- Sayid and Nadia (The Incident, Part 1)
- Sawyer - Sawyer's letter (The Incident, Part 1)
Locke is the only character who has a flashback and can't relate it to the Pilots. --Station7 21:23, May 30, 2012 (UTC)
