clonesgirl has let me know that Antena 3 have now made Capi 6 available at their site; I haven't had time to watch it all yet, but we see some more examples of Samuel realising just how different the world was back then, especially for women.
Go to Antena 3 Videos and click on La Chica de Ayer underneath the video window. Icons for all six parts of Ultimo Capitulo come up at the top right of the screen.
It's a little difficult for those of us who don't speak Spanish to get the full value yet, but I'm enjoying this series very much anyway, and I laughed at the scene where Quin is forced to apologise to a group of women and thank them for all sorts of things. (What, I don't know. But it was funny anyway.)
Do leave a comment over at lcda if you have anything to say about the episode. Most of us are not in any position for intelligent debate and analysis on the ep or the series yet, so feel free to make any observations you like!
