Viv is certainly on a roll of bad luck. She doesn't seem to confide in anyone though. I get the impression she bottles a lot of stuff up, and makes it a whole lot worse for herself. I would like to see her open up a bit more. I think her colleagues genuinely care about her, especially Jack, and he has already sensed something is up. It would be nice if she could confide in Jack. He is a great guy.
I'm not sure Sam & Jack will ever hook up again, but there's something about Sam & Martin that just doesn't sit right. She somehow doesn't seem to have the same chemistry with him that she had with Jack. I sense that she holds back with Martin, which makes me wonder if you are right with your hunch. She maybe still holds a torch for ole Jack!
If they need someone to step in as Danny's G/F, you best be ready for handbags at dawn girl, because I will fight you for that part!
I haven't seen Law & Order, but everything stops in my house for Without a Trace, Lost, Grey's Anatomy, The Shield (when it's on) & The 4400. I'm not a fan of soaps, but I do like my drama!!!!
Oh, I just had a thought... What about Jack & Viv? possible? how would that change the office dynamics?? *ponders*
