And it's taken a long, long while, but yes, tv, more than the cinema, has noticed actresses can be cast as something other than love interests and grandmothers. *appreciates*

Old!Leela is an interesting idea, though I think the clothes are bit misleading here, as Servilia spends most of her time on the show looking very elegant, but in this case she does the very Roman thing of staging her death (and her death curse) the way it should be done, which means sackcloth and ashes, literally. (Something Rome was very good at was to get across how real curses were for the people. This isn't like someone swearing "damn you" to no great affect. Atia considers herself doomed after what you've just seen.)
