Lord Grantham's face:
Thomas is still taking Lady Sybil's death hard but he's not letting his grief keep him from groping James every chance he gets. All of this is making James feel really uncomfortable. He's so serious about wanting it to stop that he tells O'Brien he's willing to go to Mr. Carson or even the police. O'Brien is not quite ready for her diabolical plan of bringing Thomas to his knees to come to a head so she urges James not to say anything.
Courtesy of Mrs. Patmore:
While Lord Grantham isn't any one's favorite person at this point, he is still reeling from Sybil's death, in his own way. Not only does he feel guilty about decisions made that night, he also believes his marriage may not bounce back from this. The Dowager was really quick to call BS on that one.
Robert's plan of sabotage backfires and Ladies Edith, Mary, Matthew, and Isobel call come to Tom's and the global Catholic population's defense. Mr. Travis is backtracking his butt off at this point and Tom comes in for the kill: baby Sybil will be baptized in the "tribe" of her father.
Anna is concerned because it's been a while and Mr. Murray has yet to meet with Mrs. Bartlett to get her statement. Lady Mary urges her to not lose hope. Things will work out. When Mr. Murry does finally meet with her, Mrs. Bartlett changes up her story.
I'd also like to give a special shout out to Mrs. Patmore for calling Ivy a hussy because she was wearing blush.
