I know from the music that plays whenever she's on screen that I'm supposed to see Clemente as a b-tch, but so far, she's the only person asking the questions that should have been asked all along. I really like the scenes where Mark is being questioned. I like watching him squirm and buckle under the questioning and I liked the shots of Stan's face as Mark dangles in the wind. I also liked the showdown between Stan and Mark in the bar-- but I was appalled by everything that happened between them afterward. (The whole "just keep your mouth shut" conversation.) It's a real problem for me when I find myself trusting one of the show's villains more than two of its key "heros." Mark should have been canned after his admission. Though it may be true that he never intends to drink again, he still lied (through omission) about being drunk during his flashforward-- then based an entire investigation on that lie.
I've been trying to figure out throughout this show why I don't like Mark (or Joseph Fiennes) as the lead. A flawed lead character can make an interesting lead character, and often does. (I'm thinking of Sipowicz from NYPD Blue) But Mark doesn't even seem to question himself or his actions at all. He's so arrogant about his flashforward being the key to everything. Some other posters have said his character isn't the lead character in the book (Simco is, I hear-- though I haven't read the book.) Maybe that's it. Maybe I'd like him and his flawed, sort of anemic yet arrogant FBI guy character as a secondary role. I don't know.
Apparently, despite my problems with the lead character, I'm still following the show closely enough to get angry about stuff like this. And maybe I'm being too impatient. Maybe Mark's flaws and screwy motives will begin to be questioned more and more as the series progresses. I hope so. I'll keep watching awhile longer to find out.
