^Haha good point!
Little things seen in the episode from
http://lost.cubit.net - WARNING: SPOILERS. Don't read if you haven't seen Maternity Leave yet!!
Dharma Caduceus Logo
In "Maternity Leave" we see a new Dharma facility - apparently some kind of medical facility with a Dharma logo containing a Caduceus.
Oceanic Airlines Mobile Connects Dharma/Others to Oceanic Flight 815
This is one of the really big nuggets of information revealed in "Maternity Leave". In the room prepared for Aaron inside the medical facility, there is a mobile containing Oceanic Airlines planes. This is pretty good evidence to suggest that Dharma or the Others (or both) have some connection with Oceanic Flight 815. The mobile and crib are similar, though not the same, as the crib and Oceanic mobile Claire saw in a dream BEFORE she was taken by Ethan, seen here. Also, the song that the mobile plays is "Catch a Falling Star (and put it in your pocket)". This is the same song that Claire asks the couple wanting to adopt Aaron about in Season 1.
Introducing Alex Rousseau
It has been a long time coming, we finally meet Danielle's daughter, Alex, in "Maternity Leave".
The Vaccine that Desmond Used
It appears the vaccine Ethan gives Claire in "Maternity Leave" is the same stuff Desmond injected himself with in "Man of Science, Man of Faith". The numbers appears on both, although the packaging is slightly different.
Mr. Friendly - master of diguise
In the medical facility in "Maternity Leave", Ethan talks to a clean shaven man who reprimands him and mentions a superior figure. This man is none other than Mr. Friendly (aka Zeke, Bluebeard, etc.). It turns out the tattered clothes, beard, knit hat, and grime are all part of an ingenious disguise!
