Caleb finally meets Trent again, all these years later, and is forcibly reminded of how Trent sometimes combined reward and punishment in ways Caleb never liked, but was told he was lucky to recieve.

Any pairings, filler's choice on whether Trent only (let's call it what it is:) abused Caleb, or the other two students as well.

+++ if Caleb still can't quite name it for what it was
++++++ the rest of the M9 get Caleb out of there, even if they can't face off with Trent yet (or if they can: they kill Trent but GOOD)
+++++++++ Caleb tells the rest of them his story.
++++++++++++++++++ He tells them for Yasha's sake.
