Just listened, but the dryer is rumbling away and the radio is turned quite low while DS settles down, so I kept missing bits. When Brenda got home from her interview, was she saying things like she needed the loo, and wanted a piece of toast, etc etc?
Looking at that written down it sounds pretty unlikely but I thought that was what I heard ...
It does seem like a surprise pg has been foreshadowed for her, after all the chat recently about how she doesn't want to be tied down by a child just yet (when Tom clearly is quite keen to breed) ... and also the dramatic tension it would create with Helen, etc.
