not sure how to increase corruption or get any scenes. The journal says to train them and wait, but its not working and i can't see any mechanics i haven't used yet.
You need to advance their personal level too. In the interact/talk menus, you will get a few special choices there to progress with their story. Once that is done, you will get a corrupt option available in the training menu. I will improve the information in game to clarify this!
