I actually like all of the new "tribe" members and I think they are trying for more realism in the story lines. It is interesting that they are trying to show how PTSD impacts the spouse. Just because he gets some help does not necessarily mean he will stop having flashbacks and nightmares. He is getting treatment ... but SHE needs to go to a support group and understand what's going on. Nobody really explained it to her and they are talking about sleep reintegration. His problems are more than sleep deprivation.
I think Gloria is very conflicted and just by the way,Jackie Clarke set up the meeting with Patrick and Jordan and that seems to be her preference. Jordan definitely seemed interested in Patrick. She said she was liking the Army "more every day". I am not sure about the fraternization between ranks.
Gloria needs to understand that Hector is also going to have some residuals from this combat experience. It could very well increase his rage ... and he is also now beholden to Tim ... and this works in his favor with Gloria. I don't know who she'll choose .. but in my opinion ... she needs more time and needs them to both agree to lack of exclusivity.
I have always really liked Catherine Bell ... since JAG! But ... I think I lean toward agreeing with you on the diminishing depth of her character.
I thought Denise was going to take over the FRG and all, but there is something off about her. She is now the last of the original "tribe" and maybe she is being written out eventually as well. Holly was in crisis, and she just left "for work" and that may be her exit route. Frank broke his ankle deplaning (?) and he is really just a non-essential character. We'll see I guess.
I do NOT like "Kat "Young with Michael at all. I see no chemistry whatsoever ... and all the acting regarding that (Michael, Kat, Denise) all felt very fake to me. icky!
