Five Previews for Terra Nova Episode 9 “Vs”

Don’t get me wrong, I really like this show, but there seems to be too many writers having different opinions within the same show, like how could the kids at the Harvest Festival know enough about a one armed General Richard Philbrook to know how he was friends with the Terra Nova commander. When he said to Shannon that the only ones around when he arrived was him and his son and they immediatly got into a gun fight and he killed the general, then hid the body for five years by burying it. There must not be an overall producer of this series to tie up loose ends and make the viewer question idiotic sub plots. Even in the last show, the fake professor killed the real professor and was about kill Shannon’s daughter before he got caught. Well what happened to him since then?
