CBBC has a cute little kids gameshow titled Raven, where the titular shapeshifting host guides a group of ten to fourteen year olds through a series of sometimes quite gruelling outdoor challenges. Each contestant has a number of lives, and every time they lose one Raven brings them back with a bit of Conspicuous CGI, no harm done. Then came the Spin-Off Series', where contestants had far fewer lives. Once they "killed" they disappeared altogether (well except for their Final Words in their send off). That these kids vanished and were never seen again was a bit creepy... but the third spin off The Dragon's Eye, took this up to eleven and turned it into Fridge Horror. Not only did the contestants vanish, but they reappeared in the final week... as a bunch of screaming, savage Feral Children, trapped and destined to wander the Forbidden Kingdom in the shadow of their failure. And if they really were meant to be the contestants (they probably just didn't want to employ a bunch of extra child actors, but still, they seemed to make a point of focussing on a couple of Ferals who they knew would be recognized) then they had clearly lost it, trapping the contestants (who can be taken as their former allies), threatening and jeering at them, and eventually locking them up probably with no intent of ever letting them out, the whole time they were together.
This also adds another layer of horror to Raven's enraged reaction to his warrior's imprisonment... those are his former students he's threatening.
