I'm sure this has been discussed elsewhere, but I haven't seen it. We heard last night that Jacob's touch meant those people couldn't kill themselves, and that his touch was "a gift". That seems pretty plausible for everyone but Sayid (giving Jack confidence, telling Kate not to steal, teling Sawyer to write his feeings down, telling Sun & Jin that their marriage was sacred, teling Hurley that he was not crazy). However, when he touched Sayid, all he did was ask for directions. Any thoughts?
