I expect some massive plot armor in favor of Kilihito. There is really no way of winning here in a "plausible" way. Or... the author could simply make Kilihito lose.
To be fair, Kilihito's 7th Gen did betray their leaders and lost everyone's trust. It only makes sense everyone's at least wary of them. It's just that previously we've been only presented with their POV (via MC).
