Write down "You don't want him spending time with that woman!"; it will matter more than it seems. It is a talky episode in the best sense: every exchange is a small duel, and nobody brought a shield. It is filler, pure enough to ship fragile parcels in. A thread left dangling since E105 gets tied off at last, neatly enough to make a librarian smile. One of the reasons people stay up too late.
