L: Lo! - - There was no outstanding moment in this episode. The big "reveal" was Desmond as the Package on Widmore's sub, but so what? Desmond's story arc concluded with the reunion with Penny. Desmond does not bring anything back to the main story line.
O: Obnoxious - - The whole Sun hitting her head and selectively missing her English speech is just bad soap opera bad gimmick. That, and the fact that the main characters have all fallen into to patterns of being drones, waiting around for something to happen (much like the audience).
S: Story line - - The big confrontation had no sizzle or bite: Flocke and Widmore speaking like feuding neighbors at the sonic fence line was a major disappointment. Two liars in a duel of lies. Not very compelling. One can assume that Widmore does not have the power to destroy Flocke (Smokey, MIB) or he would have done so at first chance.
T: Time line - - There is some thought that the sideways world is "leaking" into the main island time line; that some characters are getting deja vu signals when looking in the mirror. The problem with that is that the two worlds are not actually in sync in time. The events in the sideways world did not pick up with 815 landing in LA; significant changes had occurred in sideways world from the beginning of that time line.
