Navier did hurt her indirectly because trashta hired assassins to kill navier's parents, so she blows up a news about donation (i'm not sure about this since i mtl it, but it seems trashta made a donation in her name with navier's money, which navier prepared right after the divorce). Because trashta's reputation has been pretty bad, this news shocked her and she had premature labour. Navier didn't expect it to turn this way, but the news really had great impact on trashta.
