Sayid Jarrah (Naveen Andrews), Kate Austen (Evangeline Lilly) and Boone Carlyle (Ian Somerhalder) attempt to find where the French transmission is coming from, so they make a plan to turn on antennas at different points on the island in an attempt to triangulate the signal.

When Jack catches him with diazepam, Charlie claims he has a headache and was looking for aspirin.
