@NoNickNeeded. Well it's wasn't much since Motherglare didn't have any injury from Natsu attack and later emerged unharmed after being attacked by Atlas Flame.

Yeah, guess you are right it was Wendy magic that was responsible for the damage on Eileen scales, just like it was Wendy before who managed to wound Eileen stomach before Erza even hit her mother with the swords. But still Wendy was unable to harm Zirconis a weaker Dragon yet her magic was able to harm the former Queen of Dragons.
