Well we know the boy isn't Jacob now for sure, since he's still dead apparently. Unless 2 versions of him can exist side by side (which I suppose is still possible...but I doubt it even more now)
And not surprised to see, that Claire's "friend" is MIB just like we suspected. So how did he claim Syad? I'm starting to think he must have some power to do with death/souls so that when he died MIB claimed/infected Syad and sent him back.
I wonder how he'll go for Soyer? Or if he'll even try to use him in that way...I can't wait to see Soyer's con of MIB
Its funny, but its actually looking like Hurley might be the new protector. When Jacob mentioned Jack needing to "do something" he never mentioned him needing to take up the protector position. And Hurley really seems to be Jacob's right hand man now.
