Just before the 35 minute mark, Janine tells her, "Red leader standing by." This is a reference to Star Wars: Episode IV - A New Hope (1977) where the head of an X-Wing fighter squad says the same thing just before the attack on the Death Star.
At the end of the episode Sarina finds out she pregnant. It was to accommodate actress Yvonne Strahovski who was pregnant in real life with her third son.
