It's not unbelievable to me, because it's fundamentally who Alicia is--that's not the kind of thing you can change, because it's too essential. Alicia is someone who (a) represses her emotions, even to the point where she doesn't confess to herself what she's feeling without prodding--and since we haven't been allowed to see anyone prodding her, that's why we're finding her frustrating; and (b) operates by inertia, so unless something really earth-shattering happens to her, she's just going to drift along. She's always done this--it was just more pleasant to watch when the outside forces acting on her (Kalinda looking out for her and being a good friend; she herself getting more and more successful at her job, etc.) were forces that we could cheer for. Now that they're not, she's still drifting, but she's drifting dark instead of light.
Since we are on the topic of inertia, here are the decisions Alicia has taken this season:
- having an affair with Will
- breaking it off when it wasn't working
- putting Jackie in her place
- drinking with Diane
- Martha instead of Caitlin
- setting up that trust fund and consulting David Lee
- firing David Lee
- thanking Kalinda
- putting her children in private school
- not mellowing in terms of her separation with Peter
- walking out of the WSC grand jury thing
Some of them are pretty darn big decisions.
So what are the decisions Alicia hasn't taken, NOT counting anything in the WSC arc since it was specifically about every adult character in the show deliberately keeping Alicia out of the loop? 1.) Whether or not she wants to sacrifice more of her time with her children in favour of a future partner position; 2.) pushing through for the divorce; 3) mending things with Kalinda. The first one is a dicey one, since she herself does not know how much Diane truly meant it - this is the same firm where she is effectively shown to be powerless (Martha and Caitlin); she did, however, drink with Diane. The second comes with a mountain of issues - the future of her family, for one, and her children; her own emotional investment in Peter's political career and her awareness that without her, he might not make it very far - and the last one, a mountain of hurt. I think - no, I KNOW things would be a lot easier for her if she made up her mind on #2 and pushed through #3, but how does a person - especially one as fond as status quos, as pragmatic, as isolated and without ANY sounding board whatsoever as Alicia - just go ahead and do it?
I get the point about losing viewership, but I seriously doubt the show is in a position to suffer massive damage from this storyline - I think it's the irregular scheduling that the showrunners + network need to figure out immediately. We like our heroes to be heroi and do hero things, I know, but this show has seldom been about such things - even Alicia's greatest 'hero' moment last season, speaking for Peter in the interview, was undercut by the knowledge of Kalinda's betrayal. She ended her night in tears.
