In my hypothesis, both Delita and Ovelia die. Delita would either have died by Ramza's or Algus' sword, or he would have been killed by the Death Corps in an attempt
(SPOILER)to rescue Teta. Either way he'd be dead. The original plot Dycedarg had
(SPOILER)to kidnap Ovelia and blame it on his enemies the Nanten would have gone ahead as planned without interference from Delita or Ramza. So she would have died by the sword of Nanten's Orlandu (really Gaffgarion) in a very public way
(SPOILER)so as to put the blame on his enemies. Then, Gaff would be silenced (killed) by someone from the Hokuten. I am only theorizing of course. I totally agree that all of this would be very unlikely or even impossible because Ramza is an honorable and pure-hearted person.
