Yes, the water has run into a wall- a “dead end” as Gabe would put it… sort of like this story line. But remember kids, it’s always darkest right before the dawn… (is it, really?)
“It’s always darkest before the dawn” is like asking “How far can you run into the woods?” The answer is “half way”, because then you are no longer running into the woods (you’re running out). It is always darkest before the dawn, because the first moment it begins to get brighter, is by definition, the beginning of dawn (though it may be several hours before full daylight). Unfortunately, the aphorism doesn’t tell us how dark it will be before things turn around.
So let’s hope (or not) that this is not the literal end of the line… otherwise the water is going to fill up the cave and everyone drowns… or maybe that is the end. Quick cut to Cherry, “I wonder why Mark hasn’t called… it’s not like him” (at least under the Allen Regime…)
