Widmore is a lier but not on Smokey’s side
I just watched Recon. I’m going to trust Sawyer’s judgment and assume that Widmore is just a lier who can’t be trusted (just like “Zoe”). Widmore was in fact behind the Freighter visit although he claims not to be, and he also had the remaining Ajira passengers killed.
And Widmore doesn’t seem to be on Smokey’s side, especially considering that he brought those pylons. Whether Widmore is somehow still on Jacob’s side or just on his own remains to be seen I guess. In Lighthouse we got the impression that Jacob wants the someone who was coming to the Island to actually find the Island, and I guess that someone is Widmore.
