[Renegade 13]

I, for one, fail to see any inconsistency in the way the plot is going. Everything that has been done thus far is a logical extension of what came before. People had been cooped up on those ships for a long time, it was natural for them to want a place to settle down, whether or not that place was Earth. They didn't care, they just wanted solid ground beneath them, and so the writers wrote in a smallish storyline to go with the settling down and then the eventual relocation back up to the ships.

To me, it makes a lot more sense for people to want off the ships after a year or so of being stuffed in like sardines, than to be perfectly happy to stay on the ships, regardless of which choice would make more sense when it comes to the survival of humanity.
