Outside, the man about whose feelings the Dowager Countess couldn't care less is berating Clarkson for upsetting the family for no reason, but Clarkson urgently tells him he's worried Sybil may be toxemic and the danger of eclampsia means they must act quickly. Sir Philip tells him he sees no such danger and, in his experience, Sybil is acting normally. The show is confident enough not to draw attention to the point, but of course the fact that Clarkson has known Sybil her whole life would seem to give him a better handle on the judgment of her mental state. Instead, Clarkson asks if Sir Philip doesn't find the baby small, but the answer is not unusually so and while this goes on a bit more, Sir Philip eventually tells Clarkson that if he wishes to remain, he's going to have to be silent. Sir Philip heads back in...

...while in disasters of a different nature, Ethel has burned whatever she's got in the oven; it takes a lot of effort and some shouting to get the situation under control, which attracts Isobel from the other room. As she regards the charred contents of the tray, Ethel explains that it's a kidney soufflé. Isobel thinks that was a bit adventurous, but when Ethel offers to make something else, Isobel tells her no.

...while upstairs, a sweaty Sybil is sitting up as Branson reminds her that he has a brother in Liverpool and there might be an opening there, although it'd mean working with cars again. Sybil begs him not to think of going backwards before a contraction hits, and then she makes a comment about lying back and looking at the stars, which is enough for Branson to look in Sir Philip's direction, no doubt wondering if this qualifies as muddled thinking. Sir Philip still thinks everything's fine, but then Dr. Clarkson comes in with Cora, who clearly is still on his side and says he'd like to test the latest sample of Sybil's urine. Sir Philip starts to bluster about that, but Cora shuts him down and this looks like an excellent decision when Sybil apologizes to Dr. Clarkson for not attending to her duties (she thinks she's back working in the Downton hospital). As Sybil again starts to breathe heavily, Cora looks terribly concerned...
