okay, so tonight's "lost" episode, lockdown, promised us 5 revelations. did it deliver? to be honest, i'm just trying to figure out what the damn revelations were.

1) sayid, ana lucia, and charlie find the balloon that the cryptic henry gale described.

2) the hatch mysteriously goes into "lockdown" mode and locke gets locked in.

3) in a flashback, we learn that helen leaves lock because he chose his estranged father over her.
4) there is a mysterious map revealed in black light on the steel door in the hatch.

5) henry gale IS indeed one of the others.

i hope i got that right. otherwise, someone please enlighten me.
