Water

Mark here...this episode is called "Water" and the title refers to the fact that, thanks to a saboteur, the Galactica fleet is short of water.  The saboteur in question is Cylon sleeper agent Sharon (Boomer), who we see being apparently unaware of what she is doing but missing time.  During her missing time, she's apparently setting bombs.  In realizing this, she confides in secret lover, Chief Tyrol, who proceeds to cover it up and make excuses for her.

Meanwhile Adama and Roslin continue to be the heart of the show.  In this episode they are both dressing up for a planned meeting yet privately despising doing so.  Adama Jr. (Lee) informs Roslin that it is just to make her feel more presidential, resulting in a bit more understanding.  We do get a glimpse more into Roslin's character though.  Although Adama recognizes the necessity of civilian government, the rest of the military shows skepticism towards her. She dismisses this and shows herself as hard-nosed as any military personnel.

Laurel here...not much to add except I'm looking forward to seeing how they resolve the fact that different cylon models are out in the world playing the same character in two places at once.  For example Sharon in this episode is on the ship and has a relationship with chief tyrol, but on caprice she is rescuing Helo and maybe falling in love with him?  I'm looking forward to seeing how this all works out!
