[Lauren [is Lost]]

Yes, i think it is quite possible that Ben was trying to summon Locke back in S1. However i also agree that it can't be that simple...for example, why would Ben want the smoke to kill Eko? Unless he felt that Eko was a threat, which tbh is quite possible. Also it would make sense that Ben would send smokey after the pilot in the pilot...obviously to stop him from contacting the real world, and to cut off the losties from any information that might give something away...
