A Noah for our modern times, Mark heads into the rapidly draining swamp to find a way to save its inhabitants. Positive vibrations all around.
Mark said he would arrive in time for dinner. Which means that Pop's pre-dinner sojourn to the swamp had less to do with looking for Mark than it did with violating God's law. From behind. On top of Andy.
Mark never showed up to eat, but that didn't stop Pop from enjoying his dinner, as well as a cup of joe afterwards. Pop vows to search for Mark, as well as Andy (who's already taken the initiative to search for his friend), soon.
"Soon" has yet to arrive 8 hours later, and now Mark has been unaccounted for overnight. Pop makes the responsible decision to spread the worry around but remains uninclined to actually go out and look for him.
Will Pop actually stick to his word and head out to the swamp? Hard to say. There is lunch to be eaten and staring to do. Other people may call about Mark as well. Who else is going to take that call? His reverse-bottomed daughter? Unlikely. Stay tuned.
