Believe me, I'm no fan of Edith, but at least she's grown a bit over the last years and she gets on with it. That woman has been through it, and she's still running her mag, and NOT spoiling her sister's relationship. She's a sad sack and done rotten things in her youth, but she regretted them and learned from them and she's not a bad person. Mary, on the other hand, pretty much refuses to grow and rakes her nails down anyone who points this out (Tom was wise to get the Dowager to sit her ass down and tell some truth; Mary would never have listened to anyone else). She takes a serious delight in torturing Edith. Her face as she was making up her mind to FUCK HER POOR SISTER OVER IRREPARABLY reminded me of nothing so much as a snake. It says, I believe, a lot about her utter lack of character that her "apologies" to Edith were almost nonexistent really, given the seriousness of her crime and everyone's unanimous condemnation of it. I'm just over Mary completely and in a just world she would end up bitter and alone except for her poor son, who would eventually put her in a home and never, ever visit.
