So, after a long struggle, the Big Bad has been defeated. He has been sent to a jury, found guilty of his evil deeds, finally sent to prison, and good riddance. Unless it's a Cardboard Prison, we'll never meet him again. However, that was not the grand finale. The story continued, and a new big bad emerged. At some point, either the new big bad or the hero himself is sent to prison as well. This time, we can see in full detail how they get into prison, how he walks to his cell with the other prisoners insulting from the nearby cells, and finally, his cell. Guess what, you'll have to share it. Meet your new cellmate! Oh, wait, you already knew each other? If it's the hero, being in a cell with his former enemy will simply makes things even worse than simply being in prison would be. And if it's another villain, the old villain may work as a mentor of villainy, or how to do things inside of prison, or even plan a escape ploy together (which may be followed by a Villain Team-Up). This trope is a specific form of The Bus Came Back.
