Last year, when the final four happened, same case senerio, Cowboy was told to he had to use the veto to save one person, in which case sending the next person home. That was also the only way he was safe, to get the veto. Unless they chance the rules this year, which I don't think they've mentioned, Ivette would be safe. Plus, it seems, especially to spare April's emotions, Maggie would put up Ivette next to Janelle.
