Yeah, but she was doing all that sticking by stuff while holding her nose and keeping Walt as far away as she could before, just fine.
Now she is actively comforting him, which is not required, it is entirely optional. Feels like a strange transition to me, unless Walt really went the extra 500 miles to convince her he had changed and given up everything about being a meth lord.
This abrupt transition from "I hope your cancer comes back" to this new, friendlier wife role is quite jarring. I can't say I find it totally believable at this point. And there's no way, to the point of the NYT article she wrote, the "ladies should always stand by their man" crowd could be pissed off about her behavior in the latest episodes!
I mean, Walt pretty much bet 100% on her turning on him in the conversation with Hank. It's fine that she didn't, probably not legally practical to do that even if she still hated Walt .. but her newfound empathy for Walt as demonstrated in the bathroom scene really shocked me. I just don't understand what Walt could have done to earn that since we saw him last, because she was (understandably!) so adamant that he was a monster. You may begrudgingly keep a monster in the basement if you have to, but you don't hug the damn thing.
