It seems she now consideres Danzig a monster kind of opponent who needs to be eliminated.
But it's strange, after Glyph 'death' she felt totally powerless but now her attitude changed quickly or indeed Glyph attack did to Danzig more than we see and he is slower, maybe some internal bleeding so Bern now just takes care of injured monster remowing all his claws.
But since Danzig is one of the people who created Mary and with that May los an arm, then Danzig attempted rape on Bern, 'killing' Glyph without any remorse or anything and telling he would do the same to Bern originally, that needs some retribution.
