Lost "easter eggs" from Fire plus Water
In the official Lost podcast, it's mentioned that viewers should keep an eye
out for a building in the London skyline, where we'd see something special. Well, if you snoozed through the episode
like I did, you may have missed the scene in question. It turns out that, during the scene following the botched music
video Charlie is trying to get finished, you quickly
see the building talked about. This building is the same one you can find on the cover of the Pink Floyd album,
"Animals". Not exactly sure where the significance lies beyond that.
The other scene mentioned in online posts from Damon Lindelof is from the second dream sequence Charlie has, though you can only see it fully when viewed with an HDTV. In the upper-left corner of the screen, just over the trees, you can see the drug plane fly by and crash, then the dove appears. Without an HDTV, you can barely make out part of the plane going through the trees.
(Oh, and if you're a Veronica Mars fan, Wednesday's episode paid a small homage to Lost)
