I rewatched the season finale again (for no reason other than it was good) and although it had occurred to me before, I just now actually asked myself this question. I wanted to get some other opinions/theories on this one:
What was with the look that MIL (Man In Locke) gave to Jacob when Ben mentioned Moses?
It was a knowing look, kind of like “there’s a name I haven’t heard in a while.” How would Moses factor into the relationship between MIB (or MIL) and Jacob? Or is this just one of those fake outs that the crew is good for pulling?
