At the end of the previous episode, President Laura Roslin was left with five little words that have been eating at her. Commander Adama is a Cylon. Of course, it was a Cylon who told her on his way to execution, but still, in these times, one doesn’t know just who might be a Cylon. Things are further complicated when Adama shows up with Colonel Saul Tigh's wife Ellen in tow. Ellen was long-presumed dead and when Saul sees her he’s overcome with joy. Adama is more guarded however, as he doesn’t quite buy Ellen's story – that she was in a hospital unconscious – given her history of marital infidelity. While Adama wants to make Tigh happy, he first wants Ellen tested as a Cylon (on the sly) before giving his full approval.
