Did you see the Desmond-centric episode "The Constant" on Thursday? You should watch it at ABC.com. It was such a mindtrip. From Desmond's point of view, the episode wasn't jumping back and forth as usual but it was more linear (with a twist) as we follow Desmond's soul/consciousness literally bounce back and forth between 1996 and 2004. It's getting more and more evident that the Lost island belongs in some sort of space-time anomaly caused by electromagnetic energy, which prevents the survival of women who conceive there, the agelessness of the currently M.I.A. Batmanuel Other character, and the accelerated age of young Walt.
Speaking of Batmanuel:
Anyhow, my psyche could use a temporal leap through time and space - by that, I need to go to sleep. Goodnight (good morning).
