Yeah, I definitely figure out the metaphor a few years ago. Whether it came late or not, it was an apt time for them to say it, considering how they'd basically been walking and travelling without a home for a whole seasons worth of episodes by the time they said it. Between The Farm/The Prison, they'd spent so much time being stationary and holding their ground, it wouldn't have really worked as well. At least by this point they've actually been walking for awhile lol
