As tough as the story is to see unfold - even for someone like myself who doesn't have any experience with addicts or alcoholics - I'm glad to see it continue, and not have cutaways to overly cutesy dates or gag strips or the like. That would just be some serious Mood Whiplash, and pretty choppy storytelling. Unpleasant, difficult, and confronting as this arc may be, it's one of the most important and serious ones in a while. It needs to play out.
I'm sure if Faye does end up having to go to hospital, it's not going to do much to restore Dora's image with readers who are already upset with her. For my part, I still think her hand was forced, and she was justified in the firing. I also think some people might be misinterpreting the "insubordination" speech; to me, it sounded like she was saying "Look, I put up with your quirks, I even eat up your (metaphorical) shit and call it ice cream, but you broke the one rule I asked everyone not to break under any circumstances."
At the end of the day, Faye is an adult, and whether this is truly a sign of a deep problem or a case of the blues that got way out of hand, she needs to take responsibility for her actions. One can sympathise with her, but that doesn't hand her a Get Out Of Jail Free card for anything and everything she does that's hurtful or objectionable.
I sympathise with Faye, but I also sympathise with Dora, who had to make a tough decision, and wasn't out of line given the circumstances (prior warnings, an understandable zero-tolerance rule, plenty of rope, assistant manager...it's all been covered in previous posts). I sympathise with Faye, because she's going through an awful time, quite likely has a serious problem, and is hitting rock bottom. I sympathise with Dora, because Faye can be extremely difficult, crossed the line here, and forced her hand.
It's natural to pick sides (especially when both characters are polarising among the fanbase), and nominate a good guy and bad guy in fiction. But honestly, I don't think there's a villain here.
Well, except Steve, of course. A friend he's known since the beginning of the strip is spiralling out of control, and all he can do is sit at home and eat cereal. What. A. Jerk.
