Thomas: He's still being Thomas, bitter and condescending to everyone. He even tries to sabotage other members of the staff -- namely Daisy and the new footman, Alfred.
Anna and Bates: With Bates in prison, Anna visits him often, and brings his ex-wife's diary so he can make notes and she can play Sherlock Holmes and try to figure out how Vera really died. Bates also has a new cell mate, and the two come to blows. Things don't look good for Mr. Bates.
O'Brien: She schemes to have her nephew Alfred brought on at Downton as a footman. And she and Thomas aren't on good terms anymore. Did something happen there that I missed? Over the course of the episode, the pair, who were once thick as thieves, bicker, fight and try to one-up each other.
Alfred: He's very tall, a bit clumsy, once worked in a hotel, and gets to make out with Martha's American maid.
Mrs. Patmore and Daisy: Daisy goes on strike when she still hasn't received her promotion, leaving Mrs. Patmore to do all the work. But much like the end of last season, when Daisy stops being a brat and actually talks to Mrs. Patmore, the two resolve their differences.
Carson: He doesn't have much to do, except be stuffy, exasperated and fawn over Mary.
Mrs. Hughes: She discovers a lump in her breast and Mrs. Patmore encourages her to go to the doctor. The tests come back inconclusive and she has to wait another two months for a new test. In the meantime, she doesn't want anyone besides the cook knowing.
Mr. Moseley: He really, really wants to be Matthew's valet when Matthew moves into "the big house." (He means Downton, not jail.) But Matthew doesn't want a valet -- he wants to live a simpler life. However, Moseley gets his wish, and ends up moving into Downton with his master.
