Like having debt or deal with her would save Gilbert's ass if he happens go relief himself in woods alone while not in presence of Rose and others :P. When taking it from that point of view I am surprised she did not continue attacking Gilbert out of revenge against all abyssal kin. Altough she may have gone bit confused if even after she teared Gilbert's magical hat off to reveal his form and then go maul him, Rose would had then raised arms against her. Not sure would it had led Kiju consider Rose a bad person because she associates in friendly terms what she sees as evil.
