[1.0.50] Maniacal slaves cannot be freed

[Shidan]

The dialogue "is freed by someone" has a dead end for maniacal personality characters. They are locked out of the "...What?! WHAT!?!?" branch, and so must take the "I'm free..." path. But they have no valid lines after that one, preventing them from triggering the AI contract for escaping, despite appearing to the player as ready to escape.
