This show doesn't know where it's going in anyway, so it's just pulling bizarre tangents out of nowhere.
Do they really think that dementia is what they should be spending their screen time on on a show about a zombie apocalypse ?
I mean, they could, and indeed have focused this episode and Daniel's character on it, but is it really a good plot point to move things forward and keep the show entertaining. Was it a good use of Daniel's character, his known history and character arch, a guy who tortured people in Mexico for a living, loved and lost his wife and daughter, and was a cold a focused 'get things done despite the costs' guy, and all the potentially interesting directions that could go, but, to have him develop mental problems,.... is that smart plot writing?
It seems like the show is treated like a collection of children's toys and each new writer can come in and make up a whole new behaviour for a character on a whim, ignore who they were and how they're shaped and just go off on a whole different and incongruous tangent with them. I'm surprised the actors don't say something. The number of loops Strand has been though that don't fit together at all, and Daniel. If anyone has watched the whole show, they'll be scratching their heads.
Their best actors are gone and going. This ship is underwater and everyone is drowning. John Dorie said it. "I don't want to be here any more", and Garret Dillahunt knew he had to get as far away from the show as possible.
I feel sorry for those left behind, well not the writers and the b grade filler characters they pull off the work experience queue, but the others trying their best to follow the directions of the directionless pilots of this aimless juggernaut.
