serious.... loed them drinking and singing... no i agree... but he and locke and echo were somehoe expelled form the hatch. and i think that thier proximity to that event caused an awakening in thier minds. Locke and ecko have both also exhiitted extrasensory abilities...

Obviously Ecko knew his faith and was now a complete person ( ie he had accomplished his goal or character arc ) and so he is now moved on Ie was ready to die.. Locke and Des still have things to do. they are important to the survival of our group. and thier awakenings have filled them with a new power to do whats right...
