This is the episode in which secrets are revealed for better or worse (for some it is definitely for worse). Major Ballard is a rather unpleasant man with a secret that jeopardizes both his life and the men he serves with on the front lines. Luckily the matron easily ferrets it out and turns him in to Lt. Col. Brett to confirm it. Meanwhile Ballard rather enjoys taunting the matron in order to tease out her secret that was alluded to in the last episode by Sister Quayle. Sister Quayle is mercifully absent throughout the episode having been suddenly and unwillingly dispatched back to England for a breather a.k.a. some soul searching to determine whether she can continue to serve under Matron Carter. (If Sister Quayle cannot serve under matron without undermining her authority, matron says Quayle will be transferred; I vote for a transfer to the casualty hospital where Major Yellin is now serving, preferably before the bomb I ordered drops on it.)
In the wake of Kitty's ending of her romance with Gillan before it even began, Gillan has decided that Kitty is too much drama and gives her the cold shoulder throughout the episode. Kitty guesses Nurse Livesey's secret and confronts her about it only to warn her to be careful. And then Livesey's attempts to receive news of her loved one results in the worst possible person discovering it. I don't know how this ends, but it won't end well.
It turns out that Livesey's secret is a German fiance who now serves (reluctantly?) for the German military. His escape, aided and abetted by Livesey, means (really) bad things for Livesey, Lt. Col. Brett, Matron Carter, and the whole hospital encampment. As Livesey's trial commences, Brett receives devastating news regarding his son serving on the front lines. Meanwhile, Livesey's trial pits friends on opposite sides of controversy. Also the colonel or whoever he is running the trial is callous, insensitive, and clueless.
Sister Quayle, called back to the encampment early by her new BFF the supply quartermaster who also incidentally discovered Livesey's secret and turned her in, returns in time to possibly destroy Lt. Col. Brett's career with her hidden piece of evidence. And yet despite her perfect opportunity to do so, Quayle instead inexplicably decides to hand over the piece of evidence to Matron Carter for destruction, accept the matron's terms and conditions of continuing work in the encampment, and puts the screws to the quartermaster for a cut of his black market sales.
Major Ballard can join Yellin (and Quayle) at the casualty hospital please.
The quartermaster and Sister Quayle deserve each other; also I'm sure the man will rue the day (if he doesn't already) of trying to forge an alliance with Quayle.
Sister Quayle has an inflated sense of her own intelligence and importance; and she's blind to the fact that this is one of the many reasons that she was passed over for promotion.
