Don't know. They lost their goal of taking Eugene to Washington DC, or Tondc as the grounders would call it. And they failed their goal of saving Beth. This latest episode they made taking dumbass Noah home their new goal and all that accomplished was getting Tyreese killed. Now it looks like they have decided to go to Dc after all just in hopes that there will be survivors there.
So, looks like we are back to pointless wandering just like after they left Herschels farm and the prison. At least we know there are surviors in Mt Weather and on the space stations... wait a minute are these two shows set in the same universe? They almost could be. The 100 just takes place a hundred years after the Walking Dead.
