I have a prediction for season four: Lady Rose is going to try and make a move on Branson. That will be slightly awkward and he will have to be strong an shoot her down because Lady Sybil was his relative and Lady Rose is far too young. Plus, she's ridiculously immature. They might be attracted to each other but Branson will have to be for the wiser as he is older with experience, thus he should be smarter to say no. Just my thoughts.
Ahhhh, love the Downton Abbey ladies: Lady Mary, Lady Sybil, and Lady Edith! I used to really really hate Edith, but she's growing on me. My obsession with that show is pretty serious; I even have dreams about it.
