could contain spoiler and read only after see last episode season 2 think about it . the guy on the north pole . center of the earth . look for abnormal magnetic behavior . they also say something about represent do we miss it again . so there be another abnormality . of course that be when the plain crash . i think this whole island be a setup . set up by her daddy . she find out about it and be look for her desmond . how else can she know what to look for . so basically it an island in a magnetic shield . all of it be fake . all the sign be there . fake beard and fake door and fake medicine and fake observation station and with fake air shaft that lead to nothing . it a project indeed and and because of the final scene in the season 2 finale i know it have to do something with desmond and his chick and her dad ( and probably libby and she weird and maybe she actually have something to do with the plane crashing and ok now i be drift off ) . also in this episode and henry gail tell michael to go to some coordinate and and he will find rescue their . this be probably some sort of door in the magnetic shield . once youre go . there be no way back . i think it pretty obvious and despite of the numerous question i still have and hope to get answer for in the next season . if you think back on what we have learn in season 1 and 2 and i be sure we will get load of answer in season 3. can not wait . can anyone agree on this theory . hope to hear from you .
