Carina really has a death wish doesn’t she?  Let’s go underwater, see the hole in the wall where the water is escaping, (how, pray tell, with no light…) swim into it (underwater) and see where it goes, all with the current, which will make it impossible to return from whence we came when it’s clear that this move leads nowhere…

But remember!  Mark, “Full of faith” and “This strip is named for me” and “I’m James Allen’s meal-ticket” Trail hasn’t lost hope here…  and Carina I guess is rising to the bait.  So stay there, Gabe, molder and rot and become cave-food while Mark and Carina fulfill their destiny!
