'Downton Abbey' Season 3 episode 6 spoilers: Mary fights for Branson

lady-mary-sybil-downton-abbey-season-3.jpgWe've got some information about the Sunday, Oct. 21 episode of "Downton Abbey," fans. We already know from the episode 5 description that Matthew's "concerns about the estate grow" and Cousin Isobel "throws Ethel a lifeline."

Now ITV has released the episode description for episode 6 and it doesn't sound as though the drama shows any signs of slowing. It reads:

Tempers fray as Isobel's kind gesture backfires.

Branson's decisions are put under scrutiny, but Mary fights his corner.

Robert and Cora's relationship suffers, can Violet make them see things differently?

As Bates's chance of freedom slips away he goes to extreme lengths.

So Isobel's attempt to help Ethel fails? Color us shocked. What really interests us is Mary taking up the fight for Branson. And do you suppose the reason Robert and Cora are having problems is because of Matthew's concern about the way the estate is being managed? We can't wait to find out.

"Downton Abbey" airs Sunday nights in the U.K. and will return to U.S. airwaves Jan. 6, 2013.
