(S06E10) Knowing this was a Desmond-centric episode, I expected us to take a major step forward in understanding the beta-verse, perhaps even experiencing it in a whole new way. Ever since the explosion at the hatch, Desmond seems to experience everything a little differently, and he's always there with his finger on the truth, even if he has no idea what that truth was.

Parallels between alpha- and beta- were running rampant throughout this episode. Fisher Stevens even returned in the beta-verse, to serve as Desmond's guide as he did once before, when Desmond was trapped in time. We got beta-appearances by Charlie, Daniel Faraday, Charles Widmore and even Eloise Hawking. Every encounter was a further step toward confusion and understanding.
