I suspect the "fatal" consequence of Gothel and Anastasia's relationship will likely be Anastasia failing to be the Guardian -- either by her own death or by killing someone else (though I can't even begin to speculate who). It seems too early to have the Guardian not only identified but being trained as the Guardian, since the Guardian fulfilling their destiny means Rumple is leaving the show.
